HyperTankz for Mac

From Sector3:

HyperTankz is a fast paced 3D arcade styled single player hover tank fighting game where you control one of four futuristic hover tanks in a non-stop battle against enemy gun towers, laser towers and tanks, while you search for and collect all of the flags to complete each level.

You get the choice of playing one of four futuristic hover tanks, each with differing speed, weight, armour and damage strength.

HyperTankz consists of three general play themes, VALLEY, ICE & DESERT, and each of these themes has five arenas to play (four in each need to be unlocked) as well as a five part campaign level called The Bunker, that you must play from start to finish in one session to complete.
