Tank War 3D from games studio Rival Edge is now available for Windows Phone 8. The game, which has been ported from iOS / Android and is powered by the Unity gaming engine, sees you take control of a minature tank that you drive around various 3D landscapes, with the aim shooting and destroying other tanks as you go. It's a variation on the perennially popular Tank Hero style of game, with extra emphasis on tank and weapons upgrades.

The game is divided into missions, each of which has a specific objective, usually centred around destroying all the other enemy tanks, but sometimes with an extra challenge thrown in. To encourage game play there's also a series of achievements to unlock (e.g. destroy 60 enemy tanks).

You start the game with a basic wooden tank, but this can be upgraded using the coins you earn for completing each of the 60 missions. In order to make progress in the later level you'll defintely need to upgrade your tank (10 different types) and weapons (20 different types) substantially otherwise you risk being destroyed by a single lucky shot from an enemy thank.
