Freeware 2D platformer with RPG elements. Seven different stats can be upgraded that allow you to do different things, including but not limited to kicking in doors, cracking locked doors, cracking security boxes, cracking your own weapons to modify them into “hybrids”, cracking other people’s weapons so they explode when fired, kicking people in the face, and shooting them with shotguns, machine guns, rocket launchers, pulse cannons, nukes, or their own reflected projectiles.

This is the part where you go “I gotta get me some of that”.
