History VideoGame / TwentyXX

* EmergencyEnergyTank: Surprisingly averted for a Mega Man-esque game. There's nothing even similar to an E-Tank or Sub-tank in this game.

''20XX'' exited Early Access on August 16th, 2017 and the full version can be purchased on Steam [[http://store.steampowered.com/app/322110/ here.]]

* A third character, Hawk, was released as DLC on February 12, 2018.

* ArtEvolution: Compare the old game banner: [[http://i.imgur.com/eBHu3Gq.jpg here]] to the current one [[http://i.imgur.com/lpluuwv.jpg here]]

** Attacks from Repros won't trigger the nastier effects some of the enemies have like Maintcores' shield reflect against anything.

** As of the August 3rd update, 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.

* 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 Rock challenge skull is active sometimes the player can forget most stage hazards are now are instant kill and end up getting themselves killed too.

''20XX'' is an {{Indie}} {{Platformer}}/{{Roguelike}} hybrid that takes heavy inspiration from the ''VideoGame/MegaManX'' series.

** '''The Tank:''' ''Armatort, the Unstoppable''. Gives several defensive abilities that allows Nina and Ace to have much better odds of surviving.
** '''The DPS:''' ''Dracopent, the Foul''. Focuses primarily on normal attacks which allows Nina or Ace to be ''Ranged [=DPS=]'' or ''Melee [=DPS=]'' respectively.

A third character, Hawk, was released as DLC on February 12, 2018.

* 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 (the Omega Model has a health bar of lights underneath his cockpit).]]

** A Job 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.

* 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 and their weapons deal halved damage. Oh, they cannot swap it and cannot get Core Augments. The only, erm, positive trait about them is that prototype augments will have their positive benefits doubled, they can potentially become [[LethalJokeCharacter Lethal Joke Characters]] because of that.

* SuckingInLines: The effect indicating that Nina or Ace are charging their weapons. It goes from yellow, to blue, to (if you have the right Core Aug) [[PurpleIsPowerful purple.]]

** 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's also the Mushroom augs which boost all stats, made complete with the face painted on the stalk.

* {{Expy}}: Nina is one of X, down to the blue armor and long-ranged buster weaponry. Similarly, Ace has red armor and melee weapons just like Zero. Subverted with Hawk, who has her own unique play style that doesn't resemble any character from the ''Franchise/MegaMan'' games.

* {{Expy}}: Nina is one of X, down to the blue armor and long-ranged buster weaponry. Similarly, Ace has red armor and melee weapons just like Zero.

* GatlingGood: The special weapon Vera.

* HomingProjectile: 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.

* InexplicableTreasureChests: They always contain goodies. Diamond chests always give primary weapons, Core chests always contain armor pieces (unless a skull challenge denies them) and the rest contain regular augs and/or cash, energy, and health.

* CloseRangeCombatant: 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.

* EarlyGameHell: The beginning of runs, especially in Defiant with challenge skulls, can be very rough until you start finding augments.

** 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 and so on. If you can work around the drawbacks, though, you can tear through your enemies.

* InexplicableTreasureChests: They always contain goodies. Diamond chests always give primary weapons, Gold chests always contain armor pieces (unless a skull challenge denies them) and the rest contain regular augs.

* MightyGlacier: The Mass Concerntrator increases Max HP and attack strength, but reduces runspeed.

* PrivateMilitaryContractors: Nina and Ace 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, a run of the game is called a Job, and the in-universe lingo for the types of robots Nina and Ace are is a Contractor.

* SpreadShot: Nina's Forkalator and Scatterblast weapons.
