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 FlameBot is the first enemy with a proper projectile that tracks after you, but it's no joke, it's 50% larger than your projectiles...that is, unless you have the FlameShot yourself.
