Contract Rush is a 2D animated Run-and-Gun platformer created by Figburn and Melon and published by 2 Left Thumbs. The first version of the game (now labeled as essentially a demo) released on Newgrounds on June 24th 2020. A full version of the game branded as Contract Rush DX would come out on Steam on July 30th 2025. The original game consists of the tutorial level for the DX version and nothing else.

Cynthia is a Bounty Hunter working for a mysterious man called Renzo who used to be a part of the Mob Empire, carrying out hits against his old partners so that he can bring back his deceased son Xel from the dead. Operating out of an unassuming cafe, it's your responsibility to complete every single contract— and definitely not to ask any questions.

The central gimmick of the gameplay is that you have very limited lives and start out very weak, but by killing enemies and exploring levels you can gather upgrades that improve your character until you reach the boss. Beware, though; the stages get tougher and tougher as they go on, so you'll need to be competitive with finding upgrades lest you find yourself underpowered for the boss at the end.

A Gaiden Game/promotional bonus level called Contract Rush: Mission Sin was released on April 27th, 2025, exploring what Sin was doing during the events of the Sod City level.
