Dual-stick shooter with auto-combining weapons. TripleShot + DrillShot = Triple Drills. Add BombShot and IceShot to that: Triple Exploding Freezing Drills. On top of the hundreds of weapon-combos, Breakers Yard also has procedurally generated levels, built-in global leaderboards and a ton of robots to crush. Xbox360 gamepad supported, but not mandatory!
The latest perk added to Breakers yard is one the shrinks the player down to half their normal size.
