There's no back-story to Light Wars. You simply jump in to one of the game's two modes, Wave and Survival, and shoot away. Wave provides pre-set groups of enemies to take down, while Survival throws everything but the kitchen sink at you. You maneuver your ship with the left analog stick, placed in the bottom left corner of the screen. To fire, you use the right analog stick to shoot in any direction. The controls work well, although gamers used to playing with actual sticks in the Geometry Wars games may need to adjust.
