Edge Invaders

A 4-player twist on Space Invaders in full 3D: aliens drift in the center of the arena while up to 4 players fly the outer edges, all firing inward, with the camera always keeping your edge at the bottom. Grab power-ups, take down boss waves, and revive teammates with an assisted kill. Race to the target score versus, or share a lives pool in co-op. Plays solo too, and an agent can join in.
