3
4	''20XX'' is an Indie {{Platformer}}/{{Roguelike}} hybrid that takes heavy inspiration from the ''VideoGame/MegaManX'' series.
5
6	Just like the ''X'' series, the goal is to make your way through each stage, discovering new powerups and abilities along the way, to fight the boss at the end. However, where ''X'' has deliberately designed stages, ''20XX'' uses a random level generator to create a unique layout filled with new items each time you play.
7
8	The plot, [[ExcusePlot such as it is]], is that two Android mercenaries, Nina and Ace, have been contracted by professors Brighton Sharp and Arlan Flat to quell a robot uprising. The duo must run, dash, shoot and slash their way through 10 different levels and defeat the hordes of renegade robots, destroy their leaders, find out who is truly responsible for the attacks and, hopefully, survive long enough to get paid.

20	''20XX'' exited Early Access on August 16th, 2017 for PC. It was later ported to Platform/PlayStation4, Platform/XBoxOne, and Platform/NintendoSwitch on July 2018.
21
22	The game has seen some post-launch support. Among the free updates, some paid add-ons were released--
23	* The first [=DLC=] character, Hawk, was released on February 12, 2018.
24	* The second [=DLC=] character, Draco, was released on July 10, 2018.
25
26	On February 13, 2020, Batterystaple announced ''VideoGame/ThirtyXX'', a DistantSequel set 1000 years later, with a release date of "30XX" (really 2021).
27	----
28	!!Tutorial complete! Prepare to die.
29
30	* OneUp: The Rebeginner. Die holding one and Ace or Nina will respawn, it does cost the hefty price of 60 nuts (and 30 soul chips to unlock).
31	* AWinnerIsYou: [=DLC=] characters Hawk and Draco have no special ending cutscenes. Beat the game and the credits will simply roll.
32	* ActionBomb: In the form of small spiderlike robots. If you get close enough they will attempt to rush you and detonate, sending fireballs in multiple directions when they do.
33	* AdvancingWallOfDoom: The ''"Flee!"'' Glory Zone room, where you have to scale a platforming challenge while fleeing an invincible curtain of Flapps that [[RubberBandAI gets faster the further away you get from it]].
34	* AfterBossRecovery: Downplayed, you might get a few health pickups, but rarely a full health recovery (from the Blue Lander). If you have certain skull modifiers enabled then you have the possibility of having no recovery at all. [[spoiler:PlayedStraight with Kingseeker, a Prototype Aug that fully heals you after defeating a boss, at the expense of no health dropping from enemies.]]
35	* AIIsACrapshoot: The basic plot of the game is that robots are going berserk, and the playable contractors must set out to stop them. [[spoiler:And then it gets {{Inverted}}; the enemies and bosses are actually functioning perfectly fine, since their intended role is to serve as obstacles for the protagonists. Nina and Ace are the crapshoots, since they ultimately turn against their creators to free themselves from their tyrannic rule.]]
36	* AllTheWorldsAreAStage: The final level [[spoiler:9 and 10]] reuse enemies and gimmick platforms from all the areas in the game.
37	* AlwaysAccurateAttack: [[spoiler:Subverted and inverted. Dr. Flat's mech switching sides causes an explosion that sends your character into a damage animation… Except apart from knockback, it does not actually decrease health and in fact invokes MercyInvincibility from the normal contact damage from the moving mech.]]
38	* AnAdventurerIsYou: The Core Augments — armor parts — can, and might, change your playstyle wildly depending which one you go for:
39	** '''The Tank:''' ''Armatort, the Unstoppable''. Gives several defensive abilities that allows the Contractors to have much better odds of surviving.
40	** '''The DPS:''' ''Dracopent, the Foul''. Focuses primarily on normal attacks which allows the players to deal more damage without special effects.
41	** '''The DPS 2:''' ''Owlhawk, the Wise''. The set focuses on special weapons and having all of them allows any character to cause a lot of damage while having tools for any situation. However, this style is limited by the amount of weapon energy the character has.
42	** '''The Jack-of-All-Trades:''' ''Oxjack, the Flash''. The set focuses on mobility and synergizes somewhat well with any playstyle, but doesn't really excel anywhere.
43	* AnimalMecha: Most bosses are based off of some sort of robotic animal, with the exceptions of Vile Visage and Perforator Alpha.
44	* {{Antepiece}}: A result of the level generator. When generating a level, the game will pick from certain stage-specific templates, and add things depending on the difficulty. For example, you might find two moving platform tracks in parallel when in a Skytemple level. The same two tracks may reappear in a later Skytemple level, but might have laser beams added onto it.
45	* AntiFrustrationFeatures:
46	** After beating a boss, you can press a Power key to set the power to that key, instead of picking it up like a normal item and having to fiddle with your powers from the pause menu briefly. You can fire special weapons without consuming energy to give your newfound power a spin and understand how it works too.
47	** On version 0.984b onward, Vending machines are guaranteed to vend at least three times before having a chance to detonate. Previously, vending machines would often spawn with only one pickup available before detonating, leading to much disappointment.
48	** The first level will ''never'' spawn Energy pickups, since you won't have any Powers to use them with until the end of that level.
49	** After defeating a boss, any bottomless pits or lava pools will no longer damage the player if then fall in, preventing KaizoTrap situations. Similarly, any traps in the boss room will disappear.
50	** Every attack deals a minimum 10 damage to chests and crates. Very helpful if you've picked up the Focusing Sagelens and deal a piddling 1 damage per basic attack.
51	** Item drops don't vanish with time, you can take your time to pick anything if a hazard or enemy is too close.
52	** A run can last very long, normally about half an hour. At the end of each level, you have the option to save your game and continue later.
53	** Soul Chips aren't affected by gravity like other normal item drops, preventing the player from losing them to a bottomless pit or falling in a very inconvenient place.
54	** Attacks from Repros won't trigger the nastier effects that some of the enemies have like the Maintcores' reflector shields.
55	** Shops have blue icons indicating whether they will appear only in the middle of the level or during the boss corridor (indicated by a skull).
56	** Upon using the small circular teleporters (commonly found in Frostor), you have a small period of invincibility. This prevents an enemy camping on it to get a cheap shot on the player and also prevents stage hazards from catching them off-guard as well.
57	** Playing on Reverent or Normal on co-op allows one player to teleport to another by holding the "pick up augment" button. This might be helpful to lead one player to a chest or to help someone cross a troublesome section of a level safely. However, this is disabled on Defiant difficulty.
58	** Falling platforms on co-op will take longer to start falling than in solo runs to prevent players from accidentally sabotaging each other.
59	** Death Lotus's boss fight, which revolves around him disappearing into the wall after making a few attacks and emerging from a randomised point, was tweaked so that a red marker would appear around the point he would emerge from. This allows Ace, who has no non-power ranged attacks, to close in on his location and start whuppin' rather than having to rush there in the hope of getting in a couple of swings before he bails.
60	** Some Disable Trap challenge rooms require you to shut down flame traps with the Splinterfrost. These rooms have been set up so that the Quantum Spook, which lets you shoot through walls, doesn't work, allowing you to actually complete them.
61	* ArmCannon: A staple of Contractors. Nina has a cannon, Ace his vibro weapons, Hawk her energy whip, but it gets silly with Draco launching his huge hammer from his arm.
62	* ArmorAsHitPoints: You can collect it periodically through various means, and it will act as a 1:1 shield protecting your hit points. While you have at least one point of armor active, you are also ImmuneToFlinching.
63	* ArtEvolution: You can check the evolution of [=20XX's=] game banners [[https://steamuserimages-a.akamaihd.net/ugc/948455381364864860/906B2D03E4ACB8B8A72ADEB9C73B9969366C5E6F/ right here]].
64	* ArmorOfInvincibility: A downplayed example: Armatort's full set will grant invincibility to stage hazards sans bottomless pits, but not to enemies.
65	* ArmorPiercingAttack: The Mortar passes through enemy shields. The Quantum Spook allows ''every'' attack to pierce shields (and walls).
66	* AsteroidsMonster: If he's not fought as the first boss, once killed for the first time, Rollster Beta will cause him to divide into two, smaller Rollsters with less health, and can divide a second time if fought late enough. The miniature hamster wheels based off of him also share this property, though they divide into only one of their weaker versions.
67	* AstralFinale: The final level [[spoiler:(both of them)]] takes place on The Station, with the Earth as a backdrop.
68	* AttackDrone: The aptly named Murderdrone repro.
69	* AuthorityEqualsAsskicking: [[spoiler:Dr. Arlan Flat, chief of the project and FinalBoss, he's quite tough as well.]]
70	* AwesomeButImpractical: The prototype augments often give you massive bonuses, but not without an equally heavy penalty, and you can get more than one. Some of the characters can work around the handicaps, but woe is the unaware soul who picks the wrong prototype at the wrong time. To give some examples.
71	** Hawk's World Igniter has bar none the highest [=DPS=] of the entire game. The catch? It is ''extremely'' energy-consuming, and even with Owlhawk's Focus (which reduces special ammo consumption by 50%), it will eat through your energy gauge before you can finish saying ''[=Twenty-Double-X=]''.
72	* BadBoss: Drs. Sharp and Flat take ''entirely'' too much pleasure in the deathtraps they put Ace and Nina through, will happily insult them for the smallest perceived slight, [[ThrownOutTheAirlock space them]] or [[StuffBlowingUp detonate their bodies]] if they fail a run, and [[spoiler:they'll both take their turns fighting you to the death should you make it far enough]].
73	* BagOfHolding: There's no real limit to how many augments you can hold. You can carry all 8 powers as well[[note]]unless your character has exclusive powers, in which case they will compete for the eight spaces for powers[[/note]], but have only 3 of them active at a time.
74	* BallsGag: The main currency of the game is Nuts (the hardware kind), with quite a few puns relating to nuts.
75	* BewareTheSillyOnes: You know Dr. Sharp? Y'know, the doofy-looking scientist who gets comically attacked by Kur in the opening? [[spoiler:Turns out, he's part of the BigBadDuumvirate and the penultimate boss. When you fight him, he sure as hell proves ''[[ThatOneBoss why]]'' he's the penultimate boss.]]
76	* BigBad: Presumably Kur, the draconic robot who can be seen attacking the city in the opening.[[spoiler:.. except he ''isn't'', as there ''was'' no attack and the whole game was just one simulation. The ''real'' BigBadDuumvirate are Drs. Sharp and Flat, the scientists in charge of creating and testing Ace and Nina.]]
77	* BigRedButton: Appears on the center of a console. [[spoiler:When you fail, it's labeled payment, and one of the scientists presses it to destroy the two robots.]]
78	* BonusStage: Glory Zones may or may not be found at the midpoint of each level. Activities range from scaling platforming courses, to destroying many enemies as quickly as possible, to special obstacle courses meant to be cleared with the use of a particular Power, often with an additional stipulation like not being allowed to take damage. Though entirely optional, completing these challenges usually offers a Core part, necessary for some powerful Set Bonuses.
79	* BoringButPractical:
80	** N-Buster for Nina and A-Saber for Ace are not the most exciting weapons of the game, but are generally well-suited for most situations. Likewise Hawk's whip, the Siphon, is not terrible to the point of being considered an EmergencyWeapon, but is by far and away her most "boring" weapon.
81	** Focusing purely on damage for the main weapons over using boss powers. As said, the N-Buster and A-Saber are incredibly versatile and don't require any energy to use, while boss powers can be more situational, and since the game is designed to expect that you won't be picking any boss power, there are no parts that outright require them. Even with a few attack power ups, Nina and Ace's main weapons will end up doing even more damage than most powers and has the added benefit of turning energy into a DumpStat, thus negating the drawback of stat boosts that are supposed to be balanced by taking away energy.
82	* BossCorridor: Before every boss in true ''Mega Man'' fashion. You'll often find some goodies inside that may or may not help you.
83	* BossDissonance: Due to how levels are formed and depending on which boss you're more used to fighting, you can have EasyLevelsHardBosses and HardLevelsEasyBosses in the same run.
84	* BossRoom: Every boss arena can have small to major changes depending how early or late you fight certain bosses.
85	* BossRush: Rush Job pits you in back-to-back boss encounters, ascending in difficulty as a normal run would do. You're still offered Augs at the end of each stage and a Shop teleporter can sometimes appear, so you're not completely outpaced by the boss strengths.
86	* BossSubtitles: Each boss, when you finally meet them, is introduced with an animated splash and a nickname or quip about the boss:
87	** Twin Astrals, Forged in Flames.
88	** Death Lotus, Prince of Plants.
89	** Eternal Star, Herald of Hope.
90	** Kur, The Gatekeeper.
91	** Perforator Alpha, Discordant Riddler.[[note]]On level 8, it becomes "[[OverlyLongName Breaker of Combos, Mother of Bullets, Queen of the Angles and the First Bots]]".[[/note]]
92	** Vile Visage, Pillar of Nightmares.
93	** Rollster Beta, Roll Free or Die.
94	** Shatterbeak, Icy Avenger.
95	** [[spoiler:Dr. Brighton Sharp, Duke of Development.]]
96	** [[spoiler:Dr. Arlan Flat, Chief Out of Control.]]
97	* BottomlessPits: Most of the generated levels float over one, with the exception being the Factory levels, which are completely closed in. Falling into one will subtract a health point before teleporting you back to the last safe ground you were touching.
98	* BottomlessPitRescueService: Having the Gapminder Repro when falling does the aforementioned Bottomless Pit teleportation, but without subtracting health.
99	* BreakingTheFourthWall: [[spoiler:The very first thing Dr. Arlan Flat does during his boss fight is destroy his own health meter, preventing you from seeing how much health he has at a glance (Flat's mech has a health bar of lights underneath his cockpit).]]
100	* BulletHell:
101	** The Twin Astrals love this, firing off waves of bullet spreads. They're called the "Touhou Twins" for a reason.
102	** Perforator Alpha likewise fires a lot of bullets, often in four directions and rotating its aim so that you must move around to avoid being Swiss cheese.
103	* ChallengeRun: Challenge Skulls, which can be activated in Defiant/Hardcore mode. Effects range from longer stages, higher enemy density, running the game 50% faster, dying instantly to hazards, and doubling damage taken from enemies.
104	* ChangingGameplayPriorities: Happens more often than not; at the start of one level you can have moderate Attack, at the end you might have a lot more Power and Owlhawk armor parts and change your playstyle considerably.
105	* ChargedAttack: All characters have some form of charge attack to increase their damage or, in Draco's case, perform an utility move.
106	** The Rippling Axe (becomes a "charged" attack if used airborne) and Plasma Blender (gets stronger the more damage it causes) cannot be charged normally.
107	** The Dracopent set revolves around charged attacks — the head will store two charged attacks at once, the arms will allow for a third-level charge, and the SetBonus causes all attacks to come out as a second-level charge, though they can still be charged for the third one.
108	** The Quint Laser can be charged, making the shot larger, stronger, and faster, though it'll also consume more energy.
109	* CloneAngst: [[spoiler:The final boss fight reveals something that's been hinted at since beta: Nina and Ace have been destroyed and recreated over and over again by Dr. Sharp and Dr. Flat for testing. The final two levels see Nina and Ace turning against their creators to break the cycle of death and rebirth.]]
110	* CloseRangeCombatant:
111	** Ace only has so much range on his default A-Saber, but has greater attack power than Nina. The Sharp Sharp Spear weapon can be used to alleviate his issues with horizontal range, however.
112	** Hawk's Siphon also has a short range, but she lacks the attack power of Ace. To compensate, her Siphon can drain energy to fuel her sub weapons.
113	* CoinOnAStringTrick: Or, rather, Nut-on-a-String, but the Nutsaving Stringwire still qualifies. 50% of all vending machine uses won't cost anything. Including the ones where Contractors donate health for nuts, [[FridgeLogic somehow]].
114	* ColossusClimb: Sort of. [[spoiler:The FinalBoss must be hit in the cockpit of his HumongousMecha, so Ace or Nina must climb a series of precarious platforms in order to be able to damage it.]]
115	* ColourCodedForYourConvenience: Stronger enemies come in different colors. Black and Red enemies are among the strongest variants.
116	* ContextSensitiveButton: The same button used to pick up augments and weapons is also used to use vending machines… Or pet Dally in the [=HQ=].
117	* CoolHelmet: All Contractors have one. They can become even cooler with Core Augments.
118	* CrateExpectations: They always carry nuts, health, energy or, rarely, augments.
119	* CriticalExistenceFailure: Players can survive just fine with 1 [=HP=]. Drop below that and they'll meet an explosive demise.
120	* CriticalStatusBuff: Crisis Overdrive increases all status if Nina or Ace's health drop to red. Crisis Timestopper freezes all enemies for 3 seconds if they drop their health to red as well. [[spoiler:Inverted with Contractor Beta, which makes you more powerful at full health, but get weaker the less health you have.]]
121	* DamnYouMuscleMemory: Every foot core augs have different commands — double jump, double jump to hover ''or'' fly, or a multi-directional air dash.
122	** The Rippling Axe will significantly change your attack patterns by turning any midair push of the attack button into a brutal vertical strike, which can lead to the same sort of problem if you're used to weapons that don't immediately remove your horizontal momentum when used.
123	** Playing with Draco feels very awkward at the start because you must press Up + Attack in order to use his charge attacks. Considering some of his attacks can propel him upwards or forward, it's very easy to mess up an input and throw yourself in harm's way.
124	* DarkReprise: Level 9's boss theme, "Apex", has bits of the main theme.
125	** When you enter a Very Safe Lab, the stage background music becomes distorted and creepy.
126	* DeathIsCheap: Not for ''you'' it isn't, as it results in you losing everything you've acquired that run. That said, [[spoiler:if Nina or Ace is destroyed, their consciousness can easily be retrieved and placed into a new body]].
127	* DeathGlare: Nina and Ace will sport one while charging their attacks. Hawk and Draco maintain their neutral expression.
128	* DenialOfDiagonalAttack: [[LampshadedTrope Lampshaded]]. Nina's N-Buster is said to need additional upgrades in order to aim in non-horizontal directions, and that she'll have to make do.
129	* DifficultButAwesome: Weapons like the Scatterblast and Plasma Blender tend to be very risky due to their short range, but they can absolutely tear apart anything short of the toughest bosses of the game in seconds if used right.
130	** Most of the prototype augs from Very Safe Labs have potent bonuses but crippling drawbacks. Sanity Converter massively increases power damage but puts a rather harsh limit on how often you can use them (each use, unless it's free because of Owlhawk's helmet or whatever, consumes ''max'' energy), Violence Enhancer gives you a powerful damage buff at the cost of taking double damage, Defiant Decree makes bosses tougher in exchange for more loot, Consuming Fury gives you a GlassCannon effect at the start of every level, Hysteria doubles pickup effects but triples damage you take, and so on. If you can work around the drawbacks, though, you can tear through your enemies.
131	** Oxjack's stuff has poor defences and requires lightning-fast platforming reflexes to use effectively, particularly the SetBonus. On the other hand, the amount of chaos you can cause with a super-mobile character in a platform game is quite high.
132	** Hawk in general. She starts out as the weakest of the four characters. Her strengths lie in her near limitless supply of energy to fuel special weapons.
133	* DifficultyByAcceleration: The Lightning and Furor challenge skulls. The first increases the speed of the game itself and the second doubles the speed of some enemies. You can have both of them active at the same time.
134	* DiscOneNuke: Finding the Dracopent's Claw (which allows an even more powerful charge) and Dracopent's Fang (next attack also becomes charged) early in the game is rare, but if you happen to bump into any of these (or both), early bosses can be slaughtered in ''seconds'' even without Attack augments, especially when combined with weapons like the Scatterblast with strong charge scaling.
135	** Finding an Owlhawk's Focus (green helmet, reduces energy consumption by half) for Hawk early on will soften one of her biggest handicaps and allow her to spam special weapons with even more freedom.
136	* DontCelebrateJustYet: Once [[spoiler:Dr. Arlan Flat]] is defeated, Nina and/or Ace must escape the self-destructing station.
137	* DroughtLevelOfDoom: Can be invoked via challenge skulls. Famine will make the game never drop health, Bankrupt will make nuts never drop, Final Destination will make all items vanish.
138	** The Kingseeker prototype aug gets rid of all health drops for the rest of the run, but you get a complete refill when you kill a boss.
139	** The Enlightenment prototype aug gets rid of virtually all bonus augs throughout the level and even deletes shops and Very Safe Labs. (It compensates for this with a free Contractor Omega at the start of each level.)
140	* DualBoss: The Twin Astrals. Their battle strategy is to teleport around the room at intervals, before using the Flameshield and firing either homing bullets or a spray of bullets. At later levels, one of them will [[TurnsRed turn red]] if the other dies, in addition to reviving with half health if not killed within 10 seconds of each other.
141	* EarlyGameHell: The beginning of runs, especially in Defiant with challenge skulls, can be very rough until you start finding augments. Especially painful if you're playing as Hawk, who starts with a weak melee attack and an equally weak but long-ranged sub weapon.
142	* EasyModeMockery: Of the '''Serious''' type. Achievements cannot be unlocked when playing on Reverent (Easy) Mode. The game doesn't outright tell you, though.
143	* ElaborateEqualsEffective: Not that Nina or Ace's regular attires aren't elaborate, but the Core Augments can change considerably the appearance of their armors.
144	* EliteMook:
145	** Gamma enemies, generally painted black and red, are much stronger and they tend to have juiced up attacks compared to their normal counterparts.
146	** Soul enemies; guaranteed to drop a Soul Chip, but far stronger, faster, and more damaging than their counterparts. Gamma enemies can appear as Soul enemies, making them even ''more'' elite.
147	* EmergencyEnergyTank: Crisis Lifebank repro will collect any health pickups close to you. They automatically self-destruct once your health gets very low, releasing some of the health they've collected.
148	* EquipmentBasedProgression: There are no [=EXP=] or level-ups here. You become stronger by finding augments and armor parts.
149	* EvilGenius: Dr. Flat [[spoiler:and Sharp]]. While [[spoiler:Sharp's]] evilness can be contested slightly, Flat's definitely a bad guy, with a background in [[TheOperatorsMustBeCrazy telemarketing]], [[DepravedDentist childhood dentistry]], and [[BreadEggsMilkSquick head of a]] [[PrivateMilitaryContractors private military corporation]].
150	* EvilKnockoff: [[spoiler:The FinalBoss sends failed, barely functional, copies of Nina and Ace against them. Some are capable of using charged attacks and are actually dangerous, while others just charge mindlessly or simply self-destruct when close enough to the heroes.]]
151	* ExactWords: Very Safe Labs. Well, the lab ''itself'' is safe. It's just that the upgrade in it might be… ''troublesome''.
152	* FinalExamBoss
153	** [[spoiler:Dr. Brighton Sharp, who wears a battlesuit equipped with all of the previous bosses' special weapons, though some of them work a bit differently than yours.]]
154	** [[spoiler:Dr. Arlan Flat as well, to a lesser extent. He doesn't attack you directly until you've dealt some damage to him, but when he does, he uses the bosses' weapons. You also have to go through some of the hazards of the previous stages just to get to a position to hit him.]]
155	* FlashOfPain: Happens to players and bosses when they get hurt.
156	* FlavorText: All over the datalore. Ranges from silly, random, to downright weird.
157	* FlunkyBoss:
158	** While Eternal Star is no slouch himself, the countless swarms of Flapps he summons throughout the fight will make it pretty difficult to get any damage against him unless you have something that can hit 'em all at once.
159	** Vile Visage will periodically retreat behind a nearly-impenetrable shield while he summons random mooks to harass you.
160	** Death Lotus summons a bomb-spitting flower whenever he digs into the wall. They're rather flimsy, but it's easy to let them pile up and cause the screen to be showered with blue missiles.
161	** [[spoiler:Dr. Arlan Flat summons clones of Nina and Ace to fight you in the intermissions of the fight. They're fragile, but some of their attacks do double damage if they hit you.]]
162	%% * {{Foreshadowing}}: In the intro, Dr. Sharp gets his hair burnt and comically shaped just like Dr. Flat's. [[spoiler:You end up fighting him at the end of Level 9.]] (Not entirely sure why this is foreshadowing.)
163	* {{Foil}}: Dr. Brighton Sharp to Dr. Arlan Flat. Going beyond the pun of their names… [[spoiler:Sharp fights you directly, wearing a power armor, and using modified versions of the special weapons you can acquire throughout the game. Flat, however, is cowardly and even though he's piloting a gigantic spider mecha, he prefers to let his "arena" fight for him, attempting to wear down the player by making them run through several trap courses while throwing defective models of Nina and Ace and eventually attacking as well]].
164	* FragileSpeedster: The Leafmetal Plating augment, reducing damage in favor of run speed.
165	--> '''Leafmetal Plating description:''' Become as fast and as durable as the wind.
166	** Oxjack's Core Augments provide little in the way of protection beyond a shield that's only active while dashing with the torso upgrade. For contrast, both Owlhawk and Dracopent let you regenerate health by killing enemies with the appropriate methods, and Armatort boosts health pickups by making some of them also grant you armour. However, Oxjack's augs let you use it in midair — multiple times, if you have the SetBonus — and allow you to quickly and efficiently charge your weapon.
167	* GameplayAndStoryIntegration: The FlavorText for the Peng enemy mentions that Dr. Flat received his own personal toy-sized model after the Board acquired the rights to it. [[spoiler:Sure enough, during the final EscapeSequence, you can find said model in what is presumably his room.]]
168	* GatlingGood: The special weapon Vera. To a lesser extent Hawk's Protorifle.
169	* GetBackHereBoss: [[spoiler:Dr. Arlan Flat.]]He runs away after taking enough damage or a set time once you damage him.
170	* GlassCannon:
171	** The aptly-named Glass Cannon augment. It improves damage while reducing maximum HP.
172	** The Violence Enhancer augment greatly increases the damage you deal, but doubles the damage you take, while Consuming Fury essentially gives you a Glass Cannon augment at the beginning of every level.
173	** [[spoiler:The Hysteria augment ''triples'' damage taken, but doubles the effect of any non-prototype augs you pick up.]]
174	* GuysSmashGirlsShoot: Ace is a close-quarters combatant while Nina makes use of long ranged weapons. The same goes for Hawk and Draco: while Hawk usually has to get close to use her Siphon to recharge her special weapons, she has no real strong melee attack; Draco, on the other hand, has access to ranged weapons, but, like Ace, his most devastating attacks are usually the melee ones.
175	* HammerSpace: While this is mostly averted since all weapons are made of energy or something similar, Ace's glaive and spear have a handle that's way too big to fit in his arm "cannon".
176	* HardModePerks: Playing on Defiant with challenge skulls always increases the quantity of Soul Chips you'll get.
177	* HaveANiceDeath: If (or when) you fail a run, you usually get a last dismissive commentary from the game. Additionally, [[spoiler:Nina and Ace have special cutscenes where they are blown to bits or flung into space at the end of failed runs]].
178	** You still get some of this even when you ''win''. Even in the rare cases it's not directly mocking you, it's definitely not positive toward you directly.
179	--> "Victory? That doesn't sound right."
180	* HelmetsAreHardlyHeroic: A rare villainous example. [[spoiler:Dr. Brighton Sharp doesn't wear anything to conceal or protect his face when fighting Nina or Ace.]]
181	* HomingProjectile
182	** Grome enemies will fire homing missiles every now and then. The thing that comes the closest to this for players is the Re-Flapp repro which will home to headbutt any enemy that gets too close to Nina or Ace.
183	** Hawk has one in the form of her Seeking Striker, which behaves similarly to the homing rockets that the Grome enemies fire.
184	* HumongousMecha: [[spoiler:Dr. Flat pilots a gigantic [[SpiderTank spider mech]].]]
185	* HyperactiveSprite: Even when standing still, all Contractors are always rocking back and forth, ready for combat.
186	* ICallItVera: The weapon you get from Perforator Alpha, a rapid-fire minigun, is actually ''called'' Vera.
187	* IdiosyncraticDifficultyLevels: Goes from Reverent (Easy), Normal, and Defiant (Hard).
188	* ImmuneToFlinching:
189	** Having any Armor points when hit will stop the flinch animation from happening and just grant mercy invincibility.
190	** Armatort's torso piece also grants this as long as you're wearing it.
191	* ImprobableAccessoryEffect: It's a roguelike, so this is a given.
192	* InexplicableTreasureChests: They always contain goodies. Diamond chests always give primary weapons (or unique secondary weapons if you're playing as Hawk), Core chests always contain armor pieces (unless a skull challenge denies them) and the rest contain regular augs and/or cash, energy, and health.
193	* InconvenientlyPlacedConveyorBelt: All over the Agnisort levels.
194	* IncreasinglyLethalEnemy: Death Lotus will create other small petal enemies to rain projectiles in his arena. If fought on later levels, the boss can create from 2 to 3 at the same time.
195	* JokeCharacter: [[spoiler:Vika and Jest. Prototypes, but functional, versions of Nina and Ace]] unlocked by finishing the game on Defiant with at least 3 skulls. They have half of the normal starting health, only 2 weapon energy, their weapons deal halved damage, and items on shop have their cost ''doubled''. Oh, and they cannot find new basic weapons nor Cores. The only, erm, positive trait about them is that prototype augments will have their positive benefits doubled; they can potentially become {{Lethal Joke Character}}s because of that.
196	* JustifiedExtraLives: Dying in a run is ''quite'' final… for that particular body. Then Nina or Ace's "soul" simply gets transplanted into a fresh new body that Sharp and Flat had been working on upgrading.
197	* KingMook: All of the bosses, with the exception of Kur, are based on normal enemies found in their stages.
198	* KleptomaniacHero: The game actively encourages you to avoid becoming this, with a healthy selection of augs that involve a tradeoff in stats, it's best to think with the way you want to play before you pick up Xcalbers and become unable to use powers.
199	* LedgeBats: Flapps have a very bad habit of knocking you into pits, lava, and the like, but ''any'' enemy in Level 9 has the potential of being one.
200	* LevelInBossClothing: [[spoiler:Dr. Arlan Flat can feel like this, as you will probably spend most of the time dealing with the obstacle course in his arena.]]
201	* LimitedMoveArsenal: You can have all special weapons available, but you can only use the 3 you equip at a time.
202	* LinearWarriorsQuadraticWizards: Owlhawk's armor set. The legs core is the only one that is usable by itself, with all the other cores relying on heavy use of Powers to be effective. However, get all of the cores, and not only do they have amazing synergy with each other, but they also provide the best SetBonus in the game. The question is, [[LuckBasedMission are you going to find all the cores in one run?]]
203	** Hawk starts out with a weak weapon and a similarly weak power, but her mixture of power pick-ups and an almost limitless supply of energy makes her extremely potent.
204	* LoadBearingBoss: [[spoiler:Killing Dr. Arlan Flat causes the entire facility to self-destruct. {{Justified\|Trope}} since he's specifically said to have installed a dead man switch in his heart to test his creations one last time should one finally kill him.]]
205	* LoadingScreen: In every level transition. They contain tips and hints on game mechanics, some which can be pretty obscure.
206	* LongRangeFighter: Nina can take down distant foes with ease, but has less default attack power than Ace.
207	* LootCommand: Augments (and Cores and weapons) must be manually picked up. [[Administrivia/TropesAreTools Thank goodness for that]] — some augs will decrease stats, and automatic pickup would result in many runs where you only have two health.
208	* LuckBasedMission: Most of the game is randomly generated, so much of the game's difficulty from one stage or run to the next depends as much on the whims of the RandomNumberGod as it does the player's own skills and choices.
209	** The items you get in a run are random, either as loot drops or as items found in shops and Very Safe Labs. This can make unlocking {{Set Bonus}}es a crapshoot, since you're not at all guaranteed to find all of the Core Augments in a set. The Patchwork Connector aug and Patchwork Integrator Prototype Augment can help with this, but they are also found at random, and the latter carries a penalty to your damage output.
210	* ManaPotion: Energy Capsules. They're very blue.
211	* MarathonBoss: [[spoiler:Dr. Arlan Flat.]] The battle can be ''very'' long if Nina or Ace are lacking in attack or power augments, as the boss will always run to the other side of a very large arena once he's hurt.
212	* MarathonLevel: Can be invoked via the aptly named "Marathon" skull. Level 9 will ''always'' be this, however.
213	* MaximumHPReduction: Some augments and prototypes offer status increase in exchange of [=HP=]. The red vending machine allows you to swap maximum health for money. The Final Shell prototype [[HPToOne drops maximum health to one 1]], exchanging it for armor in 1:2 ratio.
214	* MercyInvincibility: Every time you get hit, but it usually doesn't last very long and careless players will get hit multiple times. The Mistimed Protector augments increases the duration of post-hit invincibility, though.
215	** Bosses have a downplayed version: after a hit, there's a brief interval where other hits do half damage.
216	* MightyGlacier: The Mass Concentrator (later renamed the Forcemetal Shell) increases Max HP and attack strength, but reduces runspeed.
217	** Ace's Rippling Axe does enormous damage (at the start of a run, the Axe has the same damage on a standard attack that Nina gets on a charged shot), but only has a two-hit combo, attacks slowly, and has that weird charge-attack mechanic.
218	* {{Mon}}: Repros are tiny robots, built in the likeness of stage enemies and bosses. Pick one up and they'll float behind your character, assisting you with attacks or some form of utility.
219	* MoreDakka: Get Owlhawk's full set with Vera. Press fire. ''Watch the sparks fly.''
220	* MultipleEndings: Kinda. The overall ending is the same, but the final cutscene still is slightly different depending on [[spoiler:whether or not you choose to free Al Bot in the final level]].
221	* MythologyGag: Early builds of ''20XX'' had a [[http://20xxwiki.batterystaplegames.com/images/9/94/Vile-Spider-Animated.gif spider robot boss]] that was eventually cut and replaced by Vile Visage. [[spoiler:[[https://steamuserimages-a.akamaihd.net/ugc/865108837549389717/1D999B8A9BB09FA84F3850A5EA36666E0D7C8ACD/ Dr. Arlan Flat's spider mecha]] bears a very strong resemblance to it.]]
222	** Vile Visage's datalore entry notes that the previous guardian prior to Visage fled and Visage was built in its place. They're obviously talking about the spider boss again here.
223	** Some of the Augs allude to their introduction to their first appearance in a build, like how the Meganut [[AscendedGlitch could initially be purchased in shops]] or that the Spillover Matrix used to also convert energy to health before being {{nerf}}ed.
224	** [[https://i.imgur.com/6JpwLMP.jpg The startup artwork]] shows an early design of Nina.
225	* NewGamePlus: In a sense. The more you play, the more augments you can unlock by spending Soul Chips, adding more variety to later runs.
226	* NonLethalBottomlessPits: Unless you've activated the "Rock" skull, the bottomless pits don't kill you instantly, and instead deplete one[[note]]or four if you've activated the "Stone" skull[[/note]] health point before teleporting you back to the last safe platform you were standing on.
227	* OhCrap: [[spoiler:Nina and Ace escaping The Station on an escape pod, looking back at it through the window, then seeing it was about to explode.]]
228	* OneHitKill: Surprisingly [[AvertedTrope averted]]. Unless you use a particular challenge skull, there are no hazards or enemies that cause instant death. Touching spikes will simply deal minor damage, and falling into pits will merely subtract a unit of health and send you back to the last section of solid ground you touched.
229	* OneHitPolykill: Nina's charged attacks often do that to smaller enemies. A charged up Quint Laser is strong enough to obliterate nearly every regular enemies in its path as well.
230	* OrbitingParticleShield: Flameshield will have this effect, even stronger with all Owlhawk armor set. Minimech O. Grinder repro also serves as one, and while one of these doesn't provide much protection, three (up to ''eight'') certainly will.
231	* PaddedSumoGameplay: The "Goliath" achievement invokes this trope. It requires that you go through the entire game without picking any damage enhancing items with the Undying skull which ''doubles'' the health of every enemy in the game.
232	* PainfullySlowProjectile: The Quint Laser. It's proportionally powerful, though.
233	** One new upgrade slows down enemy shots.
234	* PassThroughTheRings: Light 'em Up challenges in Glory Zones requires players to go through some round panels to win.
235	* PathOfMostResistance: If an alternate path is generated by the level, you can bet you'll have extra platforms, enemies, and spikes waiting before you reach that crate or chest. Downplayed with Shops (or Very Safe Laboratories), as while they can have obstacles in the way, they'll always be much tamer than ones leading to extra loot.
236	* PlatformBattle: Eternal Star's arena will always have bottomless pits and movable platforms. Death Lotus' arena in later levels will have lava alongside the appearing-disappearing platforms as well.
237	* PlatformHell: Level 9 is a MarathonLevel with some of the most difficult platforming challenges in the game. It combines [[FloatingPlatforms all of]] [[TemporaryPlatform the previous stages']] [[SpikesOfDoom platforming elements]] with impunity, spices it up with [[LaserHallway Boltpairs]], [[BoobyTrap Ice Architects]], and [[{{Fireballs}} Flamespewers]] en masse, and populates them all with numerous enemies ready to block your progress and knock you into pits. On top of ''that'', probably a good 80% of the level is made up of said platforming elements, which means that when you ''do'' fall into a [[NonLethalBottomlessPits bottomless pit]], the spot [[BottomlessPitRescueService you get ported back to]] — that is, the last bit of solid, safe ground you touched — is likely to be [[CheckpointStarvation a considerable distance back.]]
238	* PlatonicLifePartners: Nina and Ace are pretty good friends, being next-door neighbors, doing their job together, and frequently [[HandshakeSubstitute fist bumping]], but they aren't shown to ever progress past being friends.
239	* PlayerNudge: Some of the Trap-based Challenge Rooms give players a hint on the [[UtilityWeapon secondary functions]] of Powers. One such example is locking a Contractor in a room full of Flamespewer traps and giving them the Splinterfrost, cueing them in to learn that the Splinterfrost can disable Flamespewers.
240	* PlayEveryDay: There are Daily Challenges where you can compete against other players in a random layout to obtain the highest score or fastest time that day. It's [[SubvertedTrope subverted]] in that ScoringPoints is the only thing that comes out of this, and there are also alternative Weekly Challenges.
241	* PowerAtAPrice: Prototype Augments, found in [[BlatantLies Very Safe Laboratories]]. They give a very strong upside, at the cost of a sharp, mostly permanent downside. Examples include the Earthmetal Plating, which massively improves your life and energy at the cost of setting your attack power back to the default level, or the Zookeeper's Burden, which [[TheBeastmaster instantly gives you one copy of every Repro]], but completely removes your ability to fire your weapon or use powers at all. Besides that, there are plenty of regular augments that also feature tradeoffs, such as the Glass Cannon that grants attack power but reduces health and the Utilifier that grants energy but reduces power damage.
242	* PowerCopying: After you defeat a boss, you have the option of obtaining a special weapon similar to one they used, or [[SubvertedTrope ditching the weapon to pick up a currency bonus or an upgrade]].
243	* PowerGlows: Glowing enemies will always drop Soul Chips, but are accordingly far more powerful than regular enemies in the level. Nina, Ace, and Hawk also glow while charging their attacks.
244	* PowerUpFood: Brain Food Lunch increases HP and Energy while restoring the latter completely.
245	* PrivateMilitaryContractors: The Contractors are heavily implied to be one: the opening cutscene has Dr. Sharp calling them for help with the robot uprising, the HQ has a contract from Dr. Flat on the corkboard, and a run of the game is called a Job. The in-universe lingo for the types of robots Nina and Ace are is a Contractor. [[spoiler:Subverted. Nina and Ace aren't actually hired guns; they're just programmed to think they are, so they have a motivation to go on the missions.]]
246	* PuzzleBoss: A downplayed example. You can, of course, wail on every boss the old-fashioned way, but certain bosses aren't directly weak to the power they're supposed to be, so you have to figure out the trick that exploits the boss's ''real'' weakness. [[spoiler:Use Vera to reflect Kur's quint lasers back at him, and Eternal Star's minions cause a chain-reaction explosion when killed with Force Nova.]]
247	* QuadDamage: Nina's Star Beam can deal four times the normal damage, but she must be ''very'' close to enemies, even more than when using the [[ShortRangeShotgun Scatterblast]].
248	* RainbowPimpGear: Just picking up the strongest armor present as opposed to aiming for a SetBonus can result in this. It's further encouraged by the Mixmatch Mastery aug, which boosts stats if armor pieces don't match with each other. Subverted in that armor pieces change color to suit the Contractor wearing it so it doesn't look too hideous.
249	* RandomDrop: Item pickups and nuts. Augments are found in shops, rarely in crates, or at the end of levels, vending machines can also drop them if they are destroyed while you have the Vendsmasher augment.
250	* RandomDropBooster: The "Scavenger" augments (Vitality, Energy, Scrapmetal, Armor). Don't count too much on them, though.
251	* RandomlyGeneratedLevels: While most levels always keep their basic layout, obstacles, enemies and augments found in them is always randomized.
252	* RedAndBlackAndEvilAllOver: The most common color palette for Gamma level enemies (the strongest kind of normal enemy) is black and red.
253	* RedOniBlueOni: [[StoryBreadcrumbs Environmental cues]] suggest this through what is presumably Ace and Nina's dormitories. Nina's door has her name neatly printed on a whiteboard hung from the front of it. Ace's door has his name spraypainted on, complete with a tally of how many bosses he's killed.
254	* ReducedManaCost: Owlhawk's Focus will reduce energy consumption of special weapons by 50%.
255	* ReluctantMadScientist: [[spoiler:Dr. Sharp, who mostly wanted to create successful artificial life capable of apparent humanity, but works with his much meaner partner because it's the only way he can get funding.]]
256	* TheReveal: [[spoiler:There is no robot invasion. There never was. The entire game has been Sharp and Flat throwing Nina and Ace repeatedly into certain death and rebuilding them in order to test and improve their robots and weapons.]]
257	* ReverseShrapnel: The Flameshield does this, creating four fireballs that orbit the user.
258	* RidiculouslyHumanRobots: Nina, who could easily pass for a human wearing PoweredArmor. Ace is never seen without his helmet (and said helmet [[ElectronicEyes shows his eyes like an LED display]]) so it's harder to tell. Both of them are also capable of eating and drinking.
259	* RollingAttack: The Glaive weapon for Ace allows him to do this if he's in the air or sliding down a wall.
260	* SadisticChoice: Gameplay wise, true to [=roguelikes=], you'll more often than not be torn choosing between the rewards offered after finishing a level or when shopping.
261	* SequenceBreaking: Having any foot armor part can allow players to skip some parts of certain levels with ease.
262	* SelectiveMagnetism: The [[PowerupMagnet Charging Magnet]] will draw in health, energy, and nuts while not affecting anything else.
263	--> '''Charging Magnet flavor text''': Maybe a world where it pulls in foes, other Contractors, and blocks [[AcceptableBreaksFromReality isn't one you'd like to live in anyway]].
264	* SequelHook: [[spoiler:After completing Dr. Flat's entry in the [[FlavorText datalore]] by beating him for the third time, said datalore entry reveals that the Board is aware of Nina and Ace's escape, and are planning on taking them back by force. 1000 years later when the sequel actually takes place, they've apparently failed, as Nina and Ace are still active.]]
265	* SetBonus: There are four armor sets in the game, each with four pieces — head, arms, torso, and legs.
266	** Armatort's set bonus grants invulnerability to stage hazards.
267	** Oxjack's set bonus allows for three mid-air dashes.
268	** Dracopent's set bonus causes all attacks to be charged attacks.
269	** Owlhawk's set bonus amplifies Powers, giving them special abilities.
270	** The Patchwork Connector lets you grab the bonus with only three pieces, leading to some weird and potentially very strong arrangements — given a ''perfect'' starting seed, for example, one could have Dracopent's legs, helmet and torso, allowing all shots to be charged, but Armatort's weapon, allowing you to fire an unlimited number of charge shots that cut through enemy projectiles.
271	*** Taken even further with Patchwork Integrator, a prototype augment, which allows you to receive the bonus of armors with mere '''''two''''' pieces. The catch? A hefty ''40% penalty'' on your attack and power damage.
272	* ShortRangeShotgun: The Scatterblast for Nina. The multiple projectiles make it strong up close, but weaker at longer ranges, and they dissipate faster — although charged shots have longer range, and a double-charged one will fire more projectiles as well. Nina with the arm core enhancer and a full Dracopent set is basically instant death to anything within about twenty feet of her except for bosses, and even those don't have much fun.
273	* ShoutOut:
274	** Quite a few to the ''Franchise/MegaMan'' franchise, being a SpiritualSuccessor to it in particular.
275	*** Nina's blue and yellow color scheme is similar to the infamous Bad Box Art Mega Man.
276	*** Nina's default weapon is called the N-Buster, and Ace's is called the A-Saber, both of which are clear references to X's default X-Buster and Zero's Z-Saber.
277	*** Dr. Brighton Sharp and Dr. Arlan Flat take some design cues from Dr. Light and Dr. Wily from the Classic ''Mega Man'' series. Sharp for his rotundness in comparison to his partner, and Flat for his [[EinsteinHair weird hair spikes]]. They're also named after musical terms, like most of the main characters from the Classic ''Mega Man'' series.
278	*** The Splinterfrost functions like a combination of the Freeze Cracker from ''VideoGame/MegaMan7'' and the Shotgun Ice from ''VideoGame/MegaManX1''. With the former, the [[http://20xxwiki.batterystaplegames.com/images/a/af/Splinterfrost.png icon for the Splinterfrost]] resembles [[https://vignette1.wikia.nocookie.net/megaman/images/b/ba/MM7-FreezeCracker-Art.jpg/revision/latest/scale-to-width-down/250?cb=20100724043500 the official art for the Freeze cracker]], and for the latter, you [[PowerCopying obtain it from a penguin themed boss]] who doesn't really use the weapon himself.
279	*** The intro cutscene features [[VideoGame/MegaMan2 the camera starting near the base of a tall building, then panning up to reveal the blue-clad protagonist staring into the distance]].
280	*** Several of the portraits for the Prototype Augments feature silhouettes that look remarkably like [[VideoGame/MegaManClassic the original Mega Man]].
281	*** The Challenge Skull that alters stage hazards (lasers, spikes, pits, etc.) to cause instant death is [[VideoGame/MegaManClassic Rock]]. The flavor text for it says to "[[NintendoHard Remember your ancestors.]]"
282	*** [[spoiler:The game ends with a space station blowing up, and the final cutscene has a shot of Nina's helmet left in the sand. It's a giant reference to ''VideoGame/MegaManZero 4''[='=]s ending, though it does subvert the original BolivianArmyEnding by panning the camera right to reveal that Nina just left her helmet and that both her and Ace are perfectly fine.]]
283	** Nina's Wave Beam upgrade shares its name and appearance with the Wave Beam from the ''Franchise/{{Metroid}}'' series.
284	** The art for the Vera looks exactly like [[VideoGame/TeamFortress2 Heavy's]] default minigun. The name is also a reference to the trope [[ICallItVera I Call It "Vera"]], which Heavy invokes with every single one of his miniguns.
285	** The Ninja Sash's artwork features a headband with an insignia-inscribed metal plate bolted to the front. [[Manga/{{Naruto}} Sound familliar?]]
286	*** It makes you run faster and its description says [[Anime/SonicX "Gotta go fast"]].
287	** There's a PowerupMagnet aug shaped like [[ComicBook/{{Magneto}} Magneto's helmet]].
288	** At the end of runs, there will be a brief comment on your run quoted from a supposed department. One such comment is [[WesternAnimation/{{Futurama}} "It's bad and it should feel bad!", and is listed as being said by "WOOP WOOP WOOP"]].
289	** Another possible end-of-run message is [[VideoGame/ChronoTrigger "But… the future refused to change."]]
290	** The Plumber Hat, which increase jump height, spent a while as a bright red cap that's almost identical to [[Franchise/SuperMarioBros Mario's]], before being replaced by a picture of a top hat on a spring. There were also the Contractor Aplha, Beta, and Omega augs which boost all stats, that resembled Mushrooms, complete with the face painted on the stalk. They too were changed, replaced by colored paper resembling blueprints.
291	** The Heart Container works almost exactly as it does in ''Franchise/TheLegendOfZelda'' series, minus the full health restore. The description for the Striking Feather also references chickens that attack in swarms when provoked.
292	** The Vibroreserve is a potato battery that looks exactly like [=GLaDOS=] in her potato body from ''VideoGame/Portal2''.
293	** The Quint Laser is based off of (and looks and behaves like) the Quad Laser used by the Mooninites in ''WesternAnimation/AquaTeenHungerForce''.
294	--> '''Quint Laser flavor text''': The bullet is enormous. There is no escape.
295	** There's a Challenge Skull named "Final Destination". The menu icon is a silhouette of [[VideoGame/StarFox Fox]]'s head with a mockup of ''[[VideoGame/SuperSmashBrosMelee Melee's]]'' [[VideoGame/SuperSmashBros Final Destination inside it]]. The flavor text for the skull is [[MemeticMutation "No items. Fox only," and ultimately references the other widespread use of the term 20XX]].
296	** The Datalore entry for the Twin Astrals gives them the nickname "The Franchise/{{Touhou\|Project}} Twins", a reference to the ''Touhou Project'' series of games, infamous for the sort of BulletHell the Twin Astrals subject you to.
297	** Hawk's Wildfire sub weapon resembles the Holy Water from ''Franchise/{{Castlevania}}'' in function. The description includes the line "[[VideoGame/CastlevaniaSymphonyOfTheNight Secrets: yes, miserable.]]"
298	** The Splintering Twinifier is named after the ''TabletopGame/MagicTheGathering'' card [[https://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=397816 Splinter Twin]], which became notable because when combined with [[https://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=430255 Deceiver Exarch]], it became a huge GameBreaker.
299	* SideView: Naturally.
300	* SpreadShot: Nina's Forkalator and Scatterblast weapons. The projectile from Splinterfrost, once it hits, fires a SpreadShot backwards from point of impact; with the full Owlhawk set, it becomes an all-directional blast.
301	* SprintShoes: The sash items (Ninja and Hyper). Boltdash augment halves the duration of your [[VideogameDashing dash]], but doubles the speed output letting you go ridiculously fast.
302	* StealthPun: The small ice platforms in [[SlippySlideyIceWorld Frostor]] are square. Assuming they'd keep that pattern in the third dimension, that would make them ''ice cubes''.
303	* SuckingInLines: The effect indicating that Nina or Ace are charging their weapons. It goes from yellow, to blue/red, to (if you have the right Core Aug) [[PurpleIsPowerful purple.]]
304	* SuspendSave: After defeating the boss of every level, you have the option to save and continue later in case you need.
305	* TakeYourTime: There's no ''actual'' pressure to hurry up or anything [[spoiler:during the final {{escape sequence}}]]. There's no timer to speak of, and the [[spoiler:wall of explosions behind you will never actually overtake you if you dawdle. In fact, it will actually ''retreat'' if you fall back for whatever reason. [[DoubleSubverted Just don't take too long.]] The explosion wall's hitbox will advance slowly, and deals ''double damage'' to you if you get caught in it]].
306	* ThemeMusicPowerUp: Snippets from the Main Menu theme can be heard during the last two levels and bosses.
307	* TooFastToStop: Collect one too many speed augments like Ninja Sash and Hypersash, and you'll find out that controlling your character will become nearly impossible.
308	* TrainingBoss: Al in the tutorial mode.
309	* TurnsRed: ''Every'' boss has the ability of doing this on later levels. Only the first few set of bosses won't do it, and even then there are some that still will.
310	* UtilityWeapon: ''Every'' boss power has some additional utility use besides just doing damage;
311	** Shadespur - Locks [[TemporaryPlatform the holographic platforms in Vaculab]] permanently. It's also the only weapon capable of firing through walls, unless you acquire a certain Aug.
312	** Splinterfrost - Disables the Flamespewer traps primarily featured in Agnisort.
313	** Mortar - Negates the shields of enemies that use them. It'll also home in on the Hive Bomb obstacles from Frostor, killing them instantly.
314	** Force Nova - In addition to blocking most enemy shots, it also permanently disables the [[LaserHallway Boltpairs]] present in Skytemple.
315	** Boomerang Blade - Can be used to grab most items from a distance.
316	** Flameshield - Normally, fireballs block a single bullet before being destroyed. They'll protect against shots from Ice Architects indefinitely, however.
317	** Quint Laser - Fully charged lasers will topple Vending Machines, granting some free pickups.
318	** Vera - Can be fired downwards while in the air to propel yourself upwards.
319	** Blast Jump - Unique to Hawk. It gives her an additional jump, damaging enemies around her as she does so, and stacks with leg core augments.
320	* VideoGameDashing: All characters are capable of this. Oxjack's armor set in particular is focused around improving this ability, granting you a projectile-negating shield while you dash and also giving you up to three air-dashes.
321	* VideoGameCaringPotential: [[spoiler:Al has been caged up during the EscapeSequence, and you can choose to free him by breaking the cage, or [[VideoGameCrueltyPotential leave him trapped inside the exploding space station]].]]
322	* VideoGameFlamethrowersSuck: While the damage on Hawk's flamethrower isn't bad, the range isn't all that impressive, and it chugs down energy like a college student preparing for their third all-nighter in a row. Averted with the fire ''flask'', however, which is brutally effective against ground targets and can be used to send damage down vertical shafts by lobbing it just short of the entrance.
323	%%* VideoGameLives: They're only available in Reverent (Easy) Mode, though.
324	* WhamShot: If you didn't get the hint that [[spoiler:Dr. Sharp and Dr. Flat are the ''true'' villains]], then you're in for quite a shock when you enter the Stage 9 boss arena [[spoiler:and find Dr. Sharp waiting for you in a suit of PowerArmor]].
325	* WallJump: Works like it does in the ''Mega Man X'' series, though it's tweaked slightly — jumping off a wall no longer pushes you away and you don't stop for a moment when jumping onto a wall, so wall scaling becomes far more fluid. One pickup even lets you stick to a specific point as long as you're pressing against the wall.
326	* WeaponizedOffspring: Eternal Star is very fond of this, spamming dozens and dozens of small Flapps to attack you as the battle rages on.
327	* WarmUpBoss: The first boss will never have any of their most dangerous gimmicks and the arena will always be the least dangerous possible.
328	* YetAnotherStupidDeath: It's not unusual for players to bite more they can chew and try to fight more enemies they can handle and get mauled to death. If the Rock challenge skull is active, sometimes the player can forget most stage hazards are now are insta-death and end up getting themselves killed too.
329	** It's possible to kill yourself by picking augments that decrease your maximum health (Glass Cannon, Leafmetal Plating…) if you don't have any armor points on you.
330	* YearX: The title, in addition to the game actually being set in that time period as a homage to [[VideoGame/MegaManClassic the original Mega Man games]].
331	* YouHaveOutlivedYourUsefulness: [[spoiler:Nina and Ace recieve "payment" [[WhyAmITicking (detonated)]] if you fail a run before reaching Level 4. Die after Level 4 (but before Level 9) and Drs.

Justified, in that they are trying to perfect the bodies of the two, and if you lose, obviously they need to get [[BodyBackupDrive new bodies]] ''somehow''…]]
