A video showing early work-in-progress footage from battles in Gratuitous Tank Battles, the RTS/Tower Defense/ Sim strategy game by Positech Games (1:29)
Positech Games has released a trailer and three more screenshots from Gratuitous Tank Battles, an RTS/Tower Defense hybrid with online elements and customisable units. The player can take the role of the defender or the attacker in a series of top-down explodey fun. A built-in map editor will allow easy sharing of custom maps and defensive challenges with other GTB players in a similar fashion to Gratuitous Space Battles's challenge system. Gratuitous Tank Battles is currently under development for PC and Mac with an expected D-Day sometime before Christmas 2011.
