The gameplay premise of PixelJunk Shooter couldn't be more simple. With everything based on what's basically a 2D plane, picking up the controller and getting started couldn't be easier. The game has you moving your ship with the left analog stick, and rotating it with the right. Missiles are fired from the ship by simply pressing the R1 button, and holding it will charge a barrage of homing missiles. But the game isn't as simple as it appears on the surface, not exactly just about blasting baddies in its subterranean caverns and tunnels.
