''Bad Rats: The Rats' Revenge'' is a physics based PuzzleGame made by [=Invent4=] Entertainment. The player must place various pieces of junk along with the eponymous rats to construct a RubeGoldbergMachine with the goal of setting off a DeathTrap and murdering a cat, [[ExcusePlot presumably]] as revenge for some past grievance.

It was the first Brazilian game to be published on Steam. Due to its SoBadItsGood consensus, it got a sequel named ''Bad Rats Show'', released in June 2016.

!!This game contains examples of:
* ActionBomb: The bomber rat blows itself up as soon as it's touched.
* BlackComedy: The microwave oven has a "cat" setting.
* TheChewToy: Those poor cats.
* KillerRabbit: One of the traps unleashes a frenzied chihuahua.
* LuckBasedMission: The physics library contains some randomized values, potentially [[SpannerInTheWorks screwing up]] an otherwise correct machine, or getting an "incorrect" machine to function. Sometimes, the ball falls off the front, effectively removing it from play and requiring a level restart.
* LudicrousGibs: Happens to the cats, at least when they're not being burned alive or vaporized. The rats can also be gibbed by explosions.
* PasswordSave: The player can start a specific level using it's password. It starts with no score.
* RefugeInAudacity: The Bomber rat is dressed as a Middle Eastern terrorist.
* RubeGoldbergMachine: The gameplay premise, where you need to get the ball to touch the objective.
* TimedMission: There's a limited amount of time in a level to complete the objective - game over if it expires. The timer is paused while the simulation is running, plus the player could still save the game ahead of time.
* TwoPointFiveD: The actual playing field is only [=2D=], but objects can and often do fall into the foreground, sometimes from random collisions.
* VillainProtagonist: The titular rats trying to kill cats.
