->''"What a strange, mysterious island! And what's this? The shore is riddled with little friend-sized footprints! Guess the tide brought them to land! How utterly CONVENIENT! But where have they gotten to? Who knows? I don't! [[CloudCuckoolander Do you? I don't! Do you? I dont!]] Do-[[LargeHam WELCOME TO BATTLEBLOCK THEATER]]! Go inside... the door."''

'''''[=BattleBlock=] Theater''''' is a 2D co-op style puzzle-[[PlatformGame platformer]] created by [[VideoGame/AlienHominid The]] [[VideoGame/CastleCrashers Behemoth]] for the Xbox 360 and Steam. The gameplay revolves around 'stages' in the decidedly gruesome prison/theatre that the game takes place in, where your character is currently locked up in, and the blocks that they are made up of. The game's co-op component is described as [[VideoGameCrueltyPotential "co-optional"]] (screwing each other over might as well be encouraged, or even mandatory), and there are many versus multiplayer gametypes, such as capturing tofu horses and shooting soccer balls into... basketball hoops. Based off their ''Alien Hominid'' PDA Games.

----
!!''[=BattleBlock=] Theater'' as a whole is an example of:

* AbnormalAmmo: Weapons and tools can be a bit strange. Perhaps the toppers are a cannon that fires suction cup darts and the bubble blower... thing that shoots some sort of highly corrosive bubble.
* BittersweetEnding: [[spoiler: You make it off the island! However, no one is the happy, cheery person they were from the beginning, and Hatty seems to have become permanently vegetative.]]
* BuffySpeak: The Narrator indulges in this.
* CatsAreMean: Cats are the ones running the theatre, responsible for keeping you locked up, and watching you traverse the dangerous obstacles they set for you. They are sticklers for yarn, however, and you can make shady trades with the security to give you extra weaponry or tools.
* CharacterCustomization: You keep gems you earn, and you can spend them to let security free some prisoners. These prisoners are actually what consists of your customizable appearance, and each one gives you a head as a prize. That's as far as it goes, however. The Narrator lampshades that much.
-->'''Narrator:''' Maybe you should invest in some clothes. You're awfully naked.
* CherryTapping: Most attacks performed with the X button don't do damage, and just push people around. That being said, it is effective for, say, moving enemies into the insta-kill trap directly behind them...
* ColorCodedMultiplayer: Teams have self picked colors. Players and other team related assets use those colors.
* CosmeticAward: The only thing you can spend gems on are prisoners that give you extra heads. There are, however, many, many of these. You'll likely have purchased all of the weapons well before finishing the story mode, while your head collection won't even be a quarter complete. You can also trade these with other people, so if people are willing, they also have potential extra value too.
** After completing the game, your character will walk around with a trophy on his back at all times (well, unless you toggle it off, anyway.)
* CrapsaccharineWorld: Everything's so bright, colorful and [[WorldOfHam ridiculous]] that its almost enough to make you forget that you're trapped on an island run by [[ANaziByAnyOtherName fascist]] cats that force you to throw yourself into horrific death courses for the entertainment of the public.
* CrossPromotion: Not only do you gain additional bonus heads for having saves from both Castle Crashers and Alien Hominid with at least one achievement, the game itself provides a character for Castle Crashers.
* DeathCourse: Pretty much everything outside of arena mode. Most of the stages have you running from point A to point B, all while saws, spikes, lasers, and numerous other things try to take you out.
* DeathIsASlapOnTheWrist: During single player, death plants you at the latest checkpoint with no lives to consider. During co-op, it is even less of an inconvenience, as dead partners tend to respawn on nearby safe surfaces. It is ''not'' a slap on the wrist in two instances, when you are finishing a level against the clock, and when it is on insane mode, where checkpoints do not exist.
* DepartmentOfRedundancyDepartment: A favorite of the narrator.
-->'''Narrator:''' Will you uncover the [[ShapedLikeItself mysterious mystery]] of the island?
* DoubleJump: The game includes one for extensive platforming. What's notable about this particular iteration is that dropping off an edge of a climbable object does not consume the first jump, allowing for you to cross a major distance without touching the ground.
* EmptyShell: [[spoiler: Hatty is reduced to a seemingly permanent vegetative state by the end of the game.]]
* GainaxEnding: The stinger. [[spoiler: Hatty is dumped overboard, and that infernal top hat lands on his head. It glows red, then green... and then a laser shoots upwards from it, apparently knocking the boat away and destroying numerous other things in its path.]] This is even touched on by the narrator, who says "It all makes sense now!"
* GenreSavvy: The Narrator, once again. When touching upon the top hat on Hatty's head, the Narrator makes mention of the fact it glows red. As everyone knows, glowy red stuff is ''always'' bad.
* GoombaStomp: Not present in the main game, but is present in others in the multiplayer. In some it only counts as a non-lethal hit, in others it is an instant kill.
* GottaCatchThemAll: Not a major part of the game but something many players feel they should do. Not too hard as on the PC heads are cheap (except for a certain summer sale exclusive one). The Xbox in contrast has repeat runs periodically for any head (even the one that's summer sale exclusive on steam)
* GoshDarnItToHeck: The narrator tries to avoid profanity when possible.
-->'''Narrator:''' They're sick of Hatty's bullsh- be e- NONSENSE!
* HollerButton: Left Trigger allows you to cry for help (like a little baby). While it has the hypothetical purpose of alerting co-op partners to your presence, it can be used to call horses towards you if you need them and they are not nearby.
* HeroicBSOD: [[spoiler:Hatty appears to have been so deeply traumatized by his endeavor by the end of the game that he has given up on attempting to move from his seat, and remains unresponsive even in the presence of any of his friends.]]
* HeyItsThatVoice: The narrator of the game is played by Stamper of Newgrounds and Youtube fame.
* HyperspaceArsenal: Gems and yarns appear roughly around the same size as the player character. At most, they can collect seven gems and one yarn per levels, and then they can carry so much more in the lobbies. This also includes the weapon they are currently using, which can also be as large as the player.
* ImprobableWeaponUser: Both the prisoners and the cats can utilize an arsenal of unconventional weapons, ranging from exploding Frisbees to poisonous air bubbles to paper airplane bombs...
* IncendiaryExponent: There are a few ways to set things on fire: With the fireball weapon, or if [[MakesSenseInContext toast and lasers get involved]]. You live for a short amount of time after being ignited, and are still capable of fighting to your last breath, or even beyond if you find water, which launches you back into the air extinguished.
* ItsPronouncedTroPAY: The Narrator's description of the game's content rating in the trailer.
-->'''Narrator:''' Rated T for Blude, Veowlunce and Crud Hoomaw! Crud Hoo... what's that - like French, or something?
* LargeHam: The Narrator loves to be ridiculously over the top and hammy.
* LemonyNarrator: [[{{Cloudcuckoolander}} Extremely lemony.]]
* LudicrousGibs: Exploding weapons are the quickest way to take you enemies out. Careful, as the same applies to the player.
* MoodWhiplash: The final cutscene goes from bittersweet to peppy to weird all within the space of a few minutes.
* MotorMouth: The Narrator. All the way.
* {{Narrator}}: There is only one person who talks, and ''boy'' does he talk.
* NiceHat: Say nothing of the possible hats wearable by the player, the story revolves around a magnificent but cursed top hat possessing a friend of yours. [[spoiler:Though he doesn't seem to move very much after wearing it.]]
* NintendoHard: Furbottom's Features are always very difficult.
* PressXToDie: You need to press a certain key to enter doors in the HubLevel. If you press it anywhere else, it will make your character start trembling and eventually explode. It actually comes in handy in the Insane Mode if you want to quickly restart the level.
* ProjectilePocketing: The boomerang weapon has this trait.
* PungeonMaster: The narrator.
-->'''Narrator:''' I see them lurking in the shadows. . . lurking hard! Or Hardly lurking, see?
* SignificantAnagram: "Even the word 'hopeless' has 'hope' in it! And if you rearrange the letters, you get 'peeslosh'! ...The last part was probably unnecessary."
* SuddenMusicalEnding: [[spoiler: First comes the moving tribute to Hatty... and then an upbeat song about buckling your pants.]]
* SuperDrowningSkills: To a point that they're basically puddles, yet they're still deadly should you fall in.
* ToiletHumour: [[spoiler:Purham Furbottom, the man who created Battleblock Theater (In-Universe, of course), died because he couldn't reach the bathroom in time to take a dump, due to an illogical hatred of intermissions.]]
** The Narrator is also fond of making such jokes.
--->'''Narrator:''' [[SuperDrowningSkills Careful not to fall in that water.]] I saw somebody peeing in it.
