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!
With all nine weapons and all three perk upgrades you will lay waste to the robots of the junkyard; you still have to be careful though...
