Base Busters is a tank battle game with a good mix of both strategy and action. The aim is to lead a convoy of tanks into battle in a series of different missions.

Alternatively you can just go head-to-head or team up with someone in multiplayer mode, although the community of players seems to be very small.

You must destroy your enemy's base to win medals but you can only get so far before need to buy bigger tanks to move up the leader-boards which can only be done with in-app purchases.
