It is set in a dieselpunk universe where humans live predominantly inside enormous mega towers to escape the pollution that rendered the rest of the planet uninhabitable. You control a team of three agents tasked with storming the titular Tower 57, whose unseen Supervisor had suddenly shut down Grutin Incorporated, the largest manufacturer in the world, whose continued output is critical to the stability of the society.
Notably, the player controls one agent from a team a time; if they die, you are down to selecting one of the remaining two. The game must be started over from the checkpoint if all three are killed.
Tropes present in this game:
- 1-Up: Played with Amber Balls, which will resurrect already fallen characters if brought to a fortune teller, and are the only way of doing so. However, they can also be sold for a hefty amount of cash instead, thus letting you buy more upgrades and creating a risk-vs-reward dynamic.
- Artificial Limbs Are Stronger: Replacing agents' normal limbs with mechanical ones boosts their health and damage. However, these replacements can also be destroyed during combat in the way normal limbs cannot, leaving the agent crippled.
- Attack Drone: Flying drones are a frequent enemy, especially towards the end.
- Awesome, but Impractical: The minigun may have the highest damage output, but runs through ammo very quickly and only has one clip of ammo unlike other weapons.
- Bottomless Magazines: The sidearm carried by all of the characters is a weak Emergency Weapon that'll never run out of ammo, unlike everything else.
- Boring, but Practical: The Tommy gun; Its a automatic weapon like what one would expect and isn't particularly exciting, but it still serves as a good weapon and for crowd control when surrounded.
- Cassandra Truth: What "The Supervisor" explains regarding the situation can ultimately become this if the player character chooses not to believe him.
- Checkpoint Starvation: Often, the only checkpoint on the level occurs right before the boss battle.
- Damage Over Time: Shotguns can be upgraded with poisonous shells that do this.
- Decoy Antagonist: "The Supervisor"; seeing that I.T.G shut down years ago and the player is nothing but a programmed clone created by "Mother" for her amusement, its evident that he was nothing but a pawn in her games as well.
- Die, Chair! Die!: Most of the objects on the level are destructible.
- Difficult, but Awesome: The musket starts off as a slow semi-automatic weapon that can be troublesome when against multiple enemies, but when upgraded, gets a higher rate of fire and can fire 3 shots. This also applies to the revolver; a slower and more powerful version of the musket found in the third level.
- Expy: The "diplomat" character is essentially a spitting image of Abraham Lincoln.
- Fire-Breathing Weapon: Said diplomat also always carries a flamethrower.
- Hollywood Hacking: A hacking minigame is activated whenever you deploy a hacking glove.
- Limited Loadout: The player can carry a maximum of two extra weapons in addition to their default gun and a secondary item slot.
- Obvious Beta: Even two years after its release, the game still regularly receives Steam reviews complaining of the numerous bugs in the co-op mode.
- No OSHA Compliance: Played for laughs: there are work safety signs...which tell employees to stop reading signs and get back to work!
- Regenerating Health: Upgrading a character with a second torso will allow their health to recover on its own.
- Shock and Awe: The scientist character's default weapon is a lightning cannon.
- Shoot the Shaggy Dog: If the player is unable to kill "Mother" in 5 seconds, essentially what she says about the player being a clone meant for her amusement is true and the player will immediately die, rendering all their battles pointless and allowing her tyranny to continue for the foreseeable future.
- Spikes of Doom: Spike beds are a frequent trap on the Tower's floors.
- Surprisingly Happy Ending: If the player somehow manages to kill "Mother" before 5 seconds passes, the player will not die, declare "Mother" to be full of crap, and will instead end up ruling Tower 57 and beginning the possible cloning of pets.
- Suspiciously Cracked Wall: There are plenty of false walls on the tower's floors that'll crack when shot at, and reveal secret rooms with loot when blasted through.
- Whole Plot Reference: The game's premise of morally gray law enforcement agents of a dystopian state storming through a huge tower block full of hostiles is clearly inspired Dredd.
- You Will Not Evade Me: The policewoman character can grab enemies with it and pull them up close, so that they can then be blasted with her shotgun.
