Gridfire (AppID: 3787980)

A top-down shooter with action packed PvP combat.  Engage in FFA or team based combat with game modes like capture the flag, control points, or team deathmatch.  

You can play in a full on free for all quest for the highest score and the most kills.  But you can also play on maps with 2, 3 or 4 teams with different team based objects.  Capture all other teams flags and bring them back to your base.  Control all the points on the map.  Or engage in good old fashion team death match.

You don't have to sit up straight and use your keyboard to get competitive.  Gridfire gameplay compatible with controller based input. 

Make sure you don't just fly directly into the line of fire.  Gridfire is all about strategy.  Use a variety of weapons to force enemies to move out from under cover.  Take advantage of strategically superior positions on the map.  Some walls only allow fire through them in one direction.  Other parts of the map will speed you up in certain directions or slow you down in others.  If you play with teammates, you'll have to coordinate attacks to achieve your goals.
