Guitar Hero 5 sales not exciting enough for you? Here’s an Xbox Live Deal of the Week we can really sink our teeth into: The Harvest is going on sale for $4.99, down from $6.99.

The Harvest is an action-RPG set in a distant future in which aliens have conquered humanity. Thanks to the development of armored mech suits, the remaining pockets of humans finally have a chance to fight back. Our review praises the game’s beautiful 3D graphics, easy controls, multiple playable characters, and diversity of upgrade options.

The Harvest is that rare thing – a really impressive Windows Phone-exclusive game. But many gamers passed over it or don’t know about it due to the dreaded $6.99 price point. The sale price should help Luma Arcade’s action-RPG finally get its due.

The Harvest’s $4.99 sale begins Wednesday and will last one for week. Buy it or try the demo here (Zune link) at the Marketplace.
