Animal Revolt Battle Simulator

Animal Revolt Battle Simulator is a physics-driven battle sandbox that asks one question and then lets you answer it in as silly a way as possible: what happens when you collide multiple armies of ragdoll creatures on a map and let the simulation run? Up to seven opposing forces can take the field at once, composed of more than seventy creature types with new additions roughly every two weeks, and the fights play out as the engine flails everything together until somebody wins.

The creature builder is where most of the long-term play sits. You can stitch together custom monsters from individual body parts, bolting on as many appendages and as many weapons as you want, anywhere on the model that you want — there's no requirement that anything you make remotely resemble a functional animal. The Steam Workshop is full of player-built monsters, custom maps and buildings; you can grab someone else's six-legged sniper crab or upload your own for the next person.

Beyond freeform sandbox, the campaign mode tests whether you can actually field a coherent army. Each unit has strengths and weaknesses, point budgets force tradeoffs, and the most expensive squad doesn't reliably win against a thoughtful counter. First-person mode lets you drop into the same battles directly, armed with various ranged weapons, and contribute personally to the carnage rather than just watching it unfold.
