--> "In times of darkness... an [[RougeAnglesOfSatin angle]] of light shall descend... to bring peace to cyberspace!"

A war somewhere in Metaspace is raging. The Defiance forces in the domain (dimension in a dimensional cluster) outnumber the Enforcers' defences and outgun them with [[MoreDakka sheer firepower]]. You are an Arc Angle from the Enforcer [[LightEmUp Anti-Virus units]], an entity whose ability is to turn its enemy's shots against them. With this capability, the tides of battle may soon be turned in the Enforcers' favour.

''Arc Angle'' is a group project game in progress by {{Tropers/Ironcommando}} and his two friends, as a [[GaidenGame side story]] to ''{{Metaspace}}''. It's a ShootEmUp where enemies shoot [[BulletHell ludicrous amounts of bullets]]. However, this is one instance where it's a ''good thing'' to have loads of bullets.

Your ship has an "angle" in front of it which damages enemy bullets that fall in between, and turns the enemy bullets into holy bullets when it destroys them. Holy bullets will then home in on the enemy that spawned them, damaging the enemy. All is not easy, though--different enemies will require different tactics to destroy.

----
!! '''This upcoming game displays the following tropes:'''

* TwoAndAHalfD: Your attacks can home in on background enemies, and there are enemies that can attack you from the background as well. There is also a sense of 3-dimensional layering.
* ActionBomb: The Security Mines in Apathy. Touching them or destroying them will cause them to explode. They can also attack, but only if you "look" at them for too long with a strong weapon.
** Crystalls in Lucre and Hunger will explode into shards of shots when destroyed.
* [[spoiler: AllYourPowersCombined: The final boss Xero-Fin has the abilities of the previous seven bosses (Flunkies, ability to change all shots into white ones, homing tendrils, gravity wells, a destructive laser cannon, and a deadly version of the angle weapon that auto-kills you if you stay in it.)]]
* AlwaysAccurateAttack: Your reverser field. Any enemy shot that get in-between those two lines '''will''' take damage and converted once they are defeated.
** Crabburn's [[NukeEm P.R.A.W.N.]], should you fail to destroy it before it hits the ground.
* AnotherDimension: Which is filled with dimensional clusters (each dimension in a cluster is called a "Domain")
* AntiFrustrationFeature: Whenenver you get killed, all bullets on the screen disappear.
** If credits are spawned offscreen, they will move towards you instead of disappearing. Only if the credits moved from onscreen to offscreen will they disappear.
* AsteroidsMonster: Cellivates, which are based off amoebas.
* AttackOfThe50FootWhatever: Crabburn, who is larger than a small city.
* AttackReflector: The main gimmick of the game. Your only method of offense is to convert enemy shots by catching them between your angle.
* BanditMook: Robbirds in "Lucre" steal away your upgrade credits should they come into physical contact with you. The bandits have a long-range version where they siphon credits from you via a grappling hook-like device if they are not destroyed in time. Highwayman has a money-siphoning grappling hook, and Aurum has money-stealing webs. Fortunately, any money stolen will be recovered if you manage to destroy the enemy before they run away.
** "Seduction" has enemies that can drain away your super bar by [[PersonalSpaceInvader latching onto you]].
* BatOutOfHell: Cybats, fought in the second part of Lucre. Nor only do they [[ZergRush swarm]] around you, they can sometimes shoot huge balls of dark energy! Fortunately, they hate being shone at.
* BeatStillMyHeart: Bio-Cardiac, which looks like a large digital heart-thing.
* {{BFG}}: The BountyHunter enemies in Lucre summon InstantArmour that form a large [[RevolversAreJustBetter revolver]] onto them.
* {{BFS}}: Raiders in Lucre wield ''[[DualWielding two]]''. Their sword cannot be countered, but their SwordBeam can. Touching their blades at any time results in instant death.
* BittersweetEnding: [[spoiler: After beating both the Defiance and his own unit, Arc Angle has to leave his "home domain" behind as he is being hunted down for insubordination.]]
* BlackAndGreyMorality: [[spoiler: Neither the Defiance nor the Enforcers are very nice. In fact, ''both of them'' are the antagonists in {{Metaspace}}.]]
* BlobMonster: Cellivates in Seduction. If left alone, they will [[AsteroidsMonster split into two smaller ones]], and can attach themselves onto you to slow you down, drain your energy, and grow bigger. However, they're the easiest way to get rid of any Parasight Spores on you.
* BossFight
** BattleshipRaid: The Highwayman and Crabburn.
** BackgroundBoss: The Sleeping Spire, Highwayman, Crabburn, and [[spoiler: Xero-Fin, in his final phase]]. ''Especially'' [[AttackOfThe50FootWhatever Crabburn]].
** DegradedBoss: The System of Slumber re-appears in the boss fight against the Sleping Spire, but you only fight two of them periodically (and you cannot defeat them as you reflect their attacks back to the Sleeping Spire).
** DuelBoss: Fallen Angle.
** FinalExamBoss: The Sleeping Spire is a borderline case, you have to face off against all the enemies you fought during the level. Including the MiniBoss. Hope you know how to deal with each one...
*** [[spoiler: Xero-Fin has the abilities of all the previous bosses.]]
** FlunkyBoss: The Sleeping Spire isn't even bothered to attack, but it does have defence systems that will appear to attack you. Reverse their shots back to it to damage it.
** PuzzleBoss: Void Warp cannot be damaged directly, you have to destroy the six generators that "feed" it.
** RushBoss: Fallen Angle. His attacks come fast and are devastating, but he does not have much health for bosses of their level.
** MirrorBoss: Fallen Angle, who has an area beam like your character. Instead of reversing shots, it makes homing orbs appear all around you if you get caught in the beam.
** SequentialBoss: The Highwayman's outer armaments need to be dispatched first, after which they will drop off and expose the main generator.
*** Aurum starts off swinging from the ceiling via a web, when its health gets low it drops onto the floor, merges its legs together, and becomes a SpiderTank.
*** Crabburn has you destroying its barnacle cannons, then its outer armaments, and then its eyes. Once all those are down, it opens up its [[AttackItsWeakPoint weak point]] as a last resort weapon, which you strike ForMassiveDamage.
** StationaryBoss: The Sleeping Spire, Bio-Cardiac, and Shoop Da Whoop.
** TennisBoss: Technically all of them, as your only means of offense is to turn enemy shots aganst their attackers.
** WolfpackBoss: The System of Slumber attack in a trio, while the Null Squad is a circle of ten turrets around a main core.
* BulletHell: Though it's a ''lot'' more lenient than others, as you are able to destroy incoming enemy fire. But not all enemy shots can be destroyed...
* BreathWeapon: Crabburn and Shoop Da Whoop.
* CallARabbitASmeerp: Cars in Metaspace are known as Roaders (car-like) and Drives (animal-like with "legs").
* ChasingYourTail: Jaws in Hunger. A drone that drops food pellets will attach onto your character, and the Jaws will start chasing after the food in an attempt to eat them (and you).
** Void Warp also does this once two adjacent generators have been destroyed.
* ChestBurster: Parasight Spores, which latch onto you, drain your energy, and then explode into a Parasight if left long enough, destroying you.
* ColdSniper: The Sniper enemies in Lucre, who are paid by the Defiance to shoot you down. Start moving when their crosshairs tighten unless you want to get shot.
* ColorCodedForYourConvenience: Enemy shot hp is determined by their colour. Your ship's firepower is also determined by the colour of its "angular lines". In order of strength: Grey, Pink, [[RainbowMotif Purple, Blue, Light Blue, Green, Yellow, Orange]], [[LawOfChromaticSuperiority Red]], White/Black.
** As for the enemies themselves, the colours they are comprised of indicate what colour of shots they will fire.
* CollisionDamage: Averted with most of the enemies, although going too close to them is a good way to get shot in the face.
** Played straight in the cyber-organic level "Seduction", where many of the enemies try their best to "touch" you.
** Also played straight in the "Hunger" level, where some enemies will eat Arc Angle (or suck him into a black hole) if they touch him.
** Sorta played straight in "Lucre", the thieves don't damage you if you touch them but they will steal your money!
* CombatTentacles: Bio-Cardiac uses homing tentacle-like energy projections as an attack. Given that it was supposed to represent the sin of Lust, they may have another purpose...
** Many of the enemies in "Seduction" will use this on you. These just kill you outright.
* CompetitiveBalance: The stronger your attack, the smaller the angle it covers. (Note that each attack level is ''twice'' as powerful as the previous.) This makes a strong weapon good against the concentrated slow-moving strong shots, but less useful against the widely-spread out fast weak ones.
* CoolBike: [=KillCycles=] in Fury are motorbikes that chuck deadly firebombs from the background at you.
* CoolCar: Roaders in "Fury" are car-like entities. Drives which appear in "Lucre" and "Fury" are crosses between car and motorbikes.
* CoolTrain: The Highwayman MiniBoss of "Lucre".
* CorruptCop: The Police Drives in "Lucre" are corrupted police cars whose greed overwhelms their sense of justice.
--> "No! The city's greed has corrupted our police! They're no longer our allies anymore!"
* CounterAttack: You main (and only) method of defeating your enemies. See AttackReflector.
* CrapsackWorld: The Defiance are causing terror all over the place. [[spoiler: Even the Enforcers are major bastards too]].
* CrosshairAware: Used by enemies that attack from the background. Get out of the crosshair or get blasted.
* CueTheSun: A villainous variant here. [[spoiler: It occurs when Xero-Fin uses his LimitBreak at [[DesperationAttack low health]].]]
* {{Cyberspace}}
* DeathByMaterialism: The minecart enemies in the second half of "Lucre" shoots bullets that look like flipped money icons. Do NOT touch those.
* DeathIsASlapOnTheWrist: You don't lose any power-ups when you die (as you have none to begin with). The Revenge powerup makes it even more like this- it turns all enemy shots into holy bullets when you die, and leveling it up again causes it to fill your super bar as well.
* DestructibleProjectiles: Almost everything an enemy shoots at you can be reversed. There are some which are not, these are the ones you have to be extra cautious for.
* DifficultySpike: The second stage "Lucre", where you face off against many hard-to-destroy yellow shots. Aurum, the boss for the level is also the game's WakeUpCallBoss.
* DonutMessWithACop: The corrupt cop cars shoot laser rings from the background as one of their attacks. Wouldn't be much of this trope if not for the fact that said attack is ''called'' "Donut Beam".
* DoomedHometown: Averted. "Fury" has your character's home city and main HQ almost destroyed by Crabburn.
* ElementalAbsorption: Crystalls absorb light from your angle that is oppposite of their colour (Sapphire Crystalls absorb anything with red light, Ruby Crystalls absorb anything with blue or green). If they absorb enough energy, they will instantly aim ''and'' fire their WaveMotionGun, killing you very quickly.
* EnergyBeings: Your character, as well as the enemies.
* [[[ThreateningShark Everything Is Even Worse With Sharks]]: Jaws in Hunger, an unholy combination between a shark, a robot, and... ''VideoGame/{{Pac-Man}}''.
* EverythingTryingToKillYou: Squares, circles, polygons, etc.
* EvilCounterpart: Fallen Angle to Arc Angle. He is jealous of Arc Angle, and joins the Defiance out of spite.
* EyeBeams: Used by Parasights and Crabburn. The latter's are more like eye-flamethrowers.
* FallenHero: The Fallen Angle.
* FeatheredFiend: Robbirds in Lucre, which are hawks that swoop down and steal your money!
* FeatherFlechettes: The Robbirds' main form of attack.
* FlashOfPain: Enemies "flicker" in transparency when damaged.
* FunWithAcronyms: Crabburn's P.R.A.W.N. (Plasma-Radiated Atomizing War Nuke).
* GaidenGame: To ''{{Metaspace}}''.
* GemstoneAssault: Aurum shoots jewels at you.
* GiantEnemyCrab: Crabburn, the first MiniBoss of Fury. It's of the Fire element instead of Water, and it attacks with eye flamethrowers as well as plasma heat bubbles. ''And it's the largest enemy in the entire game''- to the point where you have to fly a few miles away from the city just for its body to fit on screen!
* GiantEyeOfDoom [=/=] {{Oculothorax}}: Parasights in Seduction... that use EyeBeams and CombatTentacles on you.
* GiantMook: Each stage has at least one.
** Apathy has the Mega-turret systems, consisting of one big turret and four smaller ones.
** Lucre has the bounty hunters (when they put on their InstantArmor), and the corrupted police [[CoolCar Drives]].
** Seduction has the Parasight Queen, a large eyeball that summon Parasights and Parasight spores, while also attacking you.
* GiantSpider [[SpiderTank Tank]]: Aurum. It shoots out "gold" and "jewels", which also makes it a literal MoneySpider.
* TheGoomba: Guardrons in Apathy are the first enemies you face. They are weak, but they too have a dangerous attack if they are left alive for too long.
* {{Greed}}: Aurum, a spider-like being that ambushes entities that fall into its dimensional portals, kills them, and hoards their gold and valuables.
** The enemies in the first half of "Lucre" also exhibit it. You fight bandits, money-driven bounty hunters, corrupt police cars, thieving birds, and a ''thief train''. All of which are after your credits!
* TheGuardsMustBeCrazy: Apathy has many enemies that don't do anything until you trip their sensors (Security Mines- trapping them in your angle, Guardrangles- getting too near)- you can sneak past most of them in a PacifistRun. Makes sense as the level is based off the sin of Sloth.
** Of particular note are Guadrangles, they will attack you only if you stand in their range for too long- if you move back out before they attack, they'll become idle again.
** Another bad offender is the Mega Turret systems, many of them appear in the background, but only a few will come out to attack you. The rest are too lazy to attack. It's a good thing for you too, as they are the level's resident [[GiantMook "large enemy"]].
* HelpfulMook: Cellivates. While they will nomally attempt to shoot you or engulf you to drain your energy, their favourite prey is Parasight Spores, which they will happily get rid of should you have one latched onto you. They also won't shoot you if you're infected with a spore.
* HitboxDissonance: Your hitbox is a few pixels wide. This will save your bacon against the huge bullet storms, but even then, homing missiles can still get you.
* HomingProjectile: Holy Bullets shots will home in on the Mook that spawned it. Many Mooks will spam these on you too.
* {{Hypocrite}}: [[spoiler: Your leader Xero-fin is one- he says that he had you destroy the previous bosses for the "sins" they commit. Your Arc Angle points out that he's committing the worst one of all-pride.]]
* IFoughtTheLawAndTheLawWon: Happens to pretty much all the bandits, raiders and bounty hunters in Lucre. Subverted when you face off against the corrupt police car things.
* ImprobableWeaponUser: Aurum's shots are essentially HardLight versions of gold and jewels.
* InstantArmor: The BountyHunter enemies summon one that forms a [[RevolversAreJustBetter large revolver]].
* InstantDeathRadius: The enemies in "Hunger" have them. Either because they're void vortexes that will instantly suck you in, tesla-coil like enemies that auto-zap you, or giant mouths that just eat you. The good news is that their radius is visible.
* ItsQuietTooQuiet: The starting part of "Lucre" has your fly down a seemingly-abandoned city... until you see an ''entire swarm'' of bandits rise out of the background and foreground!
* JustEatHim: The enemies in "Hunger" follow this trope- they chew on your character a few times if they get him, instead of swallowing him. Unfortunately, since you only take one hit to die, it doesn't really matter.
* LawOfChromaticSuperiority: Red is one of the strongest colours in the game, second only to white/black.
* LazyBum: The Sleeping Spire.
** Many of the guards in Apathy do nothing instead of attacking Arc Angle.
* LightEmUp[=/=]HolyHandGrenade: Your attack converts enemy fire into homing holy shots.
* LightIsNotGood: The corrupted Police Drives (police car things) in Lucre are holy-elemental, but thankfully they do not absorb holy bullets due to the amount of corruption present in them.
** [[spoiler: The final boss is your superior. It turns out that he worked with the Defiance and was behind all the terrorist attacks!]]
* LimitBreak: Some ''mooks'' can pull this off randomly.
** Bandits in Lucre normally chase after you while shooting you with shots, but there's a chance they will stop and spray the area with a spread of hard-to-destroy shots before chasing you again.
** Even the ''bats'' that attack in a ZergRush can pull this one too. If you see one of them [[SuckingInLines sucking in a lot of circles]], prepare to dodge the HUGE incoming shot.
* LoadsAndLoadsOfLoading: The loading for a level is kind of long.
* KnowWhenToFoldEm: The game tells you that it's sometimes better to avoid powerful shots instead of trying to destroy them. Cases in point are the yellow/orange/red shots that you see in the first stage.
* MeaningfulName: Your character, the Arc Angle. It's an arc with two lasers that form an angle!
** Your leader Xero-Fin is named after Seraphim.
** A Highwayman is a horse-riding bandit, The Highwayman takes it one step further by being a bandit train.
** The final stage is called "Self" because it represents the sin of Pride via [[ItsAllAboutMe self-indulgence]], and also because Arc Angle [[QuestForIdentity finds out more about himself]] in this level.
* MercyInvincibility: Every time you respawn, you get a few seconds worth of it.
* MilitaryMashupMachine: The Highwayman is a cross between a train, a handcar and a pirate ship.
* MiniBoss: Each stage has at least one of them.
** Apathy has the System of Slumber, three bomber-things that attack from the background.
** Lucre has the Highwayman, a train/handcar/pirate ship that attacks you from the background.
** Seduction has Bio-Cardiac. You fight his tentacles, and then he runs away.
** Hunger has Shoop Da Whoop, a giant mouth with eyes that fires its [[WaveMotionGun lazor]] from its mouth and tries to suck in the player when it charges, and Null Squad, a deadly array of turrets in a circle (which encloses the player like a mouth if left alive for too long).
** Fury has the Wreckcar, a car-thing with a large wrecking ball.
* MoneySpider: Enemies drop Credits when they die. This is because the energy data they are comprised of explodes into small fragments, which also includes the credits they carry.
** Lucre's boss Aurum takes this ''literally'', by being a GiantSpider made of money!
* MonumentalDamage: The logical conclusion when you fight the Sleeping Spire.
* MoreCriminalsThanTargets: Avarice City in Lucre, to the point where the bandits are known to steal from each other. Hell, even the ''birds'' there are criminals!
* MultiMookMelee: The fight against Sleeping Spire has you fight all the Mooks in the level, except that reversed shots will target the boss instead of the Mooks.
* NotCompletelyUseless: The grey power-level does piss-weak damage, although it has very large range (and hence one of the best ways to collect credits). It's also the only weapon that will not trigger certain dangerous enemies to attack (e.g. Security Mines) and can deal with some ZergRush enemies (Cybats, Wormicides) easily.
* OneHitPointWonder: Arc Angle is deleted in one hit. Good thing his hitbox is incredibly small...
* OnlyInItForTheMoney: The {{bounty hunter}}s and snipers in "Lucre" are trying to kill you solely because of the ludicrous credit reward that the Defiance placed on your head.
* PersonalSpaceInvader: Cellivates and Parasights in Seduction. Ironically enough, having a Cellivate attach onto you destroys any Parasights infesting you, as the Parasight sticks to them.
* PintsizedPowerhouse: Arc Angle is slightly smaller than half a human, yet he's a OneManArmy.
* PlayingWithFire: Most of the enemies and the boss of "Fury" are city-burning Defiance terrorists.
* PowerOfTheVoid: Void Warp, which is a warp hole to a [[VoidBetweenTheWorlds dimension of... nothingness]]. [[spoiler: You take it down by destroying the devices that "feed" it.]]
* PowerUpMagnet: Your "angle" is able to attract credits towards you. Your character also has a collection radius that will ensure collection of credits that enter it. You can enlarge your collection radius via upgrades.
* ProfessionalKiller: Lucre has {{Cold Sniper}}s and {{Bounty Hunter}}s, who are paid ludicrous sums of credits to kill you.
* PunBasedTitle: The game's name is a play on "arch angel".
* PunnyName:
** The Robbird enemy, which is a robber bird.
** Cellivates are cell-like enemies found in the lust-themed stage. Their name is pronounced as "salivate", which is what a lustful person does.
** Para''sight''s are [[{{Oculothorax}} eyeball parasites]].
* PyroManiac: Most of the enemies in Fury.
* RainbowMotif: Part of the colour strength spectrum, from violet being the weakest to red being the strongest.
* TheRival: Fallen Angle, who defected over to the Defiance side because he was [[GreenEyedMonster jealous of your high rank]] amongst your unit.
* RougeAnglesOfSatin: Invoked by the title. (Arc Angle instead of Arch Angel).
* SegmentedSerpent: Wormicides in Seduction, Warp Worms in Hunger.
* SetAMookToKillAMook: The organic enemies in Seduction will attack and eat their preferred prey before attacking you. Wormicides will attack and eat Cellivates, Raptorflies will grab and kill Wormicides, Parasight spores will infest and kill Raptorflies, and those spores are absorbed by Cellivates.
* SevenDeadlySins: Each of the levels are themed after each of them.
** Apathy: Themed after the Sin of Sloth. A (supposedly) high-security area where the guards have developed their leader's slacking habits. As such, the security is pretty lax in the area. Enemy trait: [[TheGuardsMustBeCrazy Security enemies cannot be bothered to attack until you trigger them]].
*** Boss- [[LazyBum Sleeping Spire]]: A StationaryBoss that doesn't do anything and can't be bothered to do so. It does, however, have an [[FlunkyBoss endless swarm of Mooks that do the dirty work]]. Cyan-coloured.
** Lucre: Themed after the Sin of Greed. A [[ViceCity city that runs on corruption and vice]], where even the thieves steal from each other. The source of this greed can be traced to the nearby "crystal mine", where a powerful being leads the hordes of bandits. Enemy Trait: Enemies drop lots of money, but [[BanditMook they can steal your money]].
*** Boss- [[{{Greed}} Aurum]]: It shoots out hard-to-destroy golden bullets along with "jewels" of varying colour. Capable of converting weaker shots into golden ones. And like many of the enemies in the level, it can [[BanditMook steal your money]]!!! Yellow-coloured.
** Seduction: Themed after the Sin of Lust. A cyber replication of a [[WombLevel bio-organic area]]. Entities in this area have organic instincts, which include the need for pleasure. A giant heart-like being enhances the growth and reproduction of the entities here. Enemy Trait: Enemies attack you with tentacles, or attempt to get "[[PersonalSpaceInvader attached]]" to you.
*** Boss- [[{{Lust}} Bio-Cardiac]]: Fires out a massive amount of pink, and purple blood cells that home in like sex-depraved maniacs, as well as trying to "touch" you with its CombatTentacles. Also, many of its bullet patterns look very suggestive. Pink-and-blue coloured.
** Hunger: Themed after the Sin of Gluttony. A domain that has been mostly devoured by entities with ThePowerOfTheVoid, and is nothing much but rather empty-looking space. The source of this can be traced to a warp hole that leads to a void dimension. Enemy Trait: [[InstantDeathRadius Enemies "eat" you if you get too close]], they can also eat bullets.
*** Boss- [[VillainousGlutton Void Warp]]: Eats up weak enemy shots and spews out much stronger ones. Also has a move where it tries to suck you in. Orange-coloured (the devices, not the warp).
** Fury: Themed after the Sin of Wrath. The Enforcer capital city of the domain is under attack by violence-loving terrorists intent on burning the city down. Destroy them and their leader before it is too late. Enemy Trait: [[PlayingWithFire Enemies attack with destructive fire-based moves]].
*** Boss- [[UnstoppableRage Crabburn]]: Attacks the player with very destructive moves, such as warheads, {{Wave Motion Gun}}s and incendiary missiles. Red-coloured.
** Spite: Themed after the Sin of Envy.
*** Boss- [[GreenEyedMonster Fallen Angle]]: MirrorBoss. Another Arc Angle member of your unit who was jealous of your position and achievements... so it [[FaceHeelTurn joined the Defiance]] just to get back at you. Green-coloured.
** Self: Themed after the Sin of Pride.
*** FinalBoss- [[spoiler: [[{{Pride}} Xero-Fin]]]]: FinalBoss. Has abilities of the above six (flunkies, conversion of shots into white ones, energy tendrils, bullet eating, {{Wave Motion Gun}}s, your bullet converter). Plus, he's a MagnificentBastard. White-coloured.
* ShoutOut: The "angle" weapon was inspired by ''ThunderForce V's'' [[http://www.youtube.com/watch?v=teeJ8Ej3R0w Free Range]] weapon.
** One of Aurum's phases attacks in a manner similar to [[VideoGame/MegaManX Morph Moth's]] coccon form.
** Checking the "do you have arachnophobia?" box under the options section will allow you to skip the fight against Aurum, as it appears dead on the floor with the text "[[MonsterParty Sorry, I'm dead]]." when you encounter it.
** [=NullSquad=], the second MiniBoss of "Hunger" is very similar to the "turret circle" from the first level of ''VideoGame/{{R-Type}}''.
** The MiniBoss of the "Hunger" stage is a vector-graphic [[MemeticMutation Shoop Da Whoop]]... When it charges his lazor, it also tries to suck you into its mouth!
** The BountyHunter enemies in Lucre can summon an InstantArmor that resembles a handgun, not unlike [[VideoGame/GunstarHeroes Seven Force's]] Blaster Force. It's also a [[Film/TheManWithTheGoldenGun golden handgun made of multiple parts]].
** The Crystall enemies come in two variants: [[VideoGame/PokemonRubyAndSapphire Ruby, and Sapphire]].
** The Raptor Fly enemies attack the Wormicides in a fashion similar to the bugs in ''VideoGame/{{Galaga}}''.
** Spawners in Seduction are an organic take on the MookMaker enemies from ''VideoGame/{{Gradius}}''.
** Jaws in Hunger follow and eat a trail of "food" pellets that a drone drops, similar to ''VideoGame/{{Pac-Man}}''. Unfortunately, the drone is directly attached onto you!
*** Also, the drone may drop a large pellet, which temporarily makes the Jaws larger and slower, and then it will head directly for you!
** [[spoiler: In the final stage, you fight against your own unit, and the FinalBoss is your superior, similar to ''VideoGame/{{Einhander}}''.]]
* SkippableBoss: Aurum can be skipped if you checked the "Do you have arachnophobia?" option under the options menu. However, it's better not to do so, as it is a ''literal'' MoneySpider that drops a lot of credits.
* SmartBomb: Holding down the left and right mouse button for a few seconds will allow you to use one, in which case your "angle" widens up to cover the whole screen while instantly destroying all enemy shots. It also makes you invulnerable to damage for a short period.
* SmashingSurvival:
** Getting engulfed by a Cellivate will require you to mash the buttons to get them off more quickly.
** Getting infected by a Parasight Spore will require you to mash the buttons to shake it loose before a Parasight explodes out of you, killing you. Or, just get engulfed by a Cellivate- their favourite meal is Parasight Spores.
* SpawnBroodling: Parasight Queens send out Parasights spores that attach onto you and kill you by exploding into a Parasight when they grow big enough.
* SpreadShot: It's easier to list the instances where this ''doesn't'' happen.
* StealthPun: Aurum is a spider-like being made of a gold-like HardLight. It also throws said gold-like substance at you. In other words, it's a ''literal'' MoneySpider.
* ThemeNaming: The levels (Apathy, Lucre, Seduction, Hunger, Fury, Spite and Self) are named after aspects of the SevenDeadlySins.
* UnrealisticBlackHole: The Void Warp, which is more of a miniature warp hole to a void dimension rather than a black hole.
* [[spoiler: UnwittingPawn: Your Arc Angle is this in the Enforcers' plan. When he finds out, he isn't pleased...]]
* VideogameSettings: All of which are [[CyberSpace digitized versions]].
** Apathy: EternalEngine
** Lucre: 1st half- ViceCity[=/=]WretchedHive, 2nd half- UndergroundLevel
** Seduction: WombLevel
** Hunger: SpaceZone
** Fury: Capital City (Enforcers')
** Spite: Nowhere
** Self: Capital City (Enforcers')
* WakeUpCallBoss: Aurum, who regularly shoots out yellow shots (near-impossible to destroy even with your current strongest weapon), and can turn all shots on the screen yellow. And he's only the ''second'' boss.
* WantedPoster: Giant ones are present in Lucre, on the city buildings. They have a picture of the Arc Angle on it, as well as a staggering bounty of $100000000000. Every time you see one of these, you will be attacked by a BountyHunter.
* WarmUpBoss: The Sleeping Spire. It doesn't attack, and its flunkies' shot patterns are relatively easy to counter.
** The System Of Slumber is also like this, even though it's a [[WolfpackBoss three-against-one]], their attacks are preceded by [[CrosshairAware crosshairs]] that tell you where they are about to attack. Plus, you can beat them with one well-timed SmartBomb.
* WaveMotionGun: Used by some of the enemies, such as Crystalls. And Crabburn.
* WeakenedByTheLight: Some enemies are harmed by the light.
** The Raptor Hawks in Fury will lose their stealth ability for a short while when shone at, allowing your shots to home in on them.
* WeakTurretGun: A lot of them appear in the first stage, Apathy.
* WhatCouldHaveBeen: Due to time constraints, the entirety of Spite had to be cut out except for the boss.
* WrapAround: The middle of the System of Slumber trio has this.
* WretchedHive [=/=] ViceCity: The first half of "Lucre" takes you through a city filled with [[BanditMook thieves]], [[BountyHunter head hunters]], [[DirtyCop corrupt police]], and a train that runs on money and greed. Beware the bandits- they can steal away your credits needed for upgrades!
* [[spoiler: YouCantGoHomeAgain: In the ending, Arc Angle has to leave his home domain behind, as he is being tracked down by the Enforcers for insubordination.]]
* ZergRush:
** Lucre has the Cybat enemies which you fight in the mine area.
** Seduction has two- Wormicides and juvenile Raptorflies, the latter of which really swarm the screen.
