When life gives you explosions, you make Explosionade. Someone gave Mommy's Best Games a huge pile of explosions, and they made this.
For a mere 80 Microsoft points, you too can have this much fun running around a mutant-infested warehouse with an extremely powerful prototype mech, collecting gold and kick ass. Explosionade is what we get from Mommy's Best Games while we wait a potential Xbox Live Arcade release of Grapple Buggy.
It's well worth the dollar. Just ignore that whole middle, not being able to make the jump bit, and go download the demo.
