Totally Accurate Battle Simulator (T.A.B.S. for short) is a ragdoll physical game that looks not entirely unlike Gang Beasts but with cannons in it. The title is in early production but developers Landfall Games need you to help.
The game is available for free to all comers in an alpha form. This means that if you want to play the game, all you have to do is ask, and the indie developer behind Clustertruck as well as this title will be happy to oblige. You can sign up at the game's website.
