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 kicking arse. 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 not being able to make the jump bit, and go download the demo.
