Cortex Command
A 2D physics sandbox where you mine gold, build bunkers and throw expendable soldiers at the enemy cortex. Every wall crumbles pixel by pixel, every plan falls apart, and that is exactly the point. Best with friends on one couch, and endlessly replayable thanks to mods.

Besiege
Besiege is a physics building game about medieval machines with one job: annihilation. Bolt together cannons, spinning blades, wings and far too many wheels, then send your creation off to flatten castles and armies. When it works, it is glorious. When it falls apart, that is usually funnier.

Totally Accurate Battle Simulator
Lead red or blue wobblers from ancient lands, spooky places and fantasy worlds, then watch the wobbliest physics decide who stays standing. With 100+ silly units, campaigns, sandbox, possession and multiplayer, it is strategy that keeps collapsing into comedy.

They Can't Stop All Of Us
A joke that became a real game: a meme-fuelled attack and defense battler where one side builds wild bases and shoots from them, and the other sends swarms of autonomous minions to tear it all down. Co-op and PvP, silly on the surface, surprisingly tactical underneath.
