At its core, Heavy Mach 2 involves accepting missions from the Command Center, outfitting your Mach's "arms" with crazy weapons, blasting enemies to smithereens, collecting various parts, earning credits and experience points, and continuing to upgrade your rig until you're the baddest on the block. There is a strong RPG-element to this version, as you are basically questing and earning points to level up. The Equipment Shop allows you to purchase various upgrades to your body, feet, and arms for maximum strength, speed, and butt-whooping. A quick trip to the Maintenance Shop allows you to play fashion show until you're satisfied with your configuration. Even the new environments are reminiscent of the various RPGs that have popped up within the iDevice landscape.
