Appolicious – As an old-school Mech Assault player, I’ve spent more hours than I care to admit playing Heavy Mach. 2 HD on my iPad. Recently, IndieApps released a follow-up: Mach Defense. This newcomer offers the same mech action as its predecessor, with the feel of a base defense game. Add a combination comic book/casual game to the mix in Imaginary Range HD (from Square Enix), plus a fresh take on solitaire and Frisbee tossing, and you’ve got yourself our must-have iPad games of the week.
