Unusual experience making in difficult to categorise. Players must have solid knowledge of the game of paper, scissors, stone and move horizontally across the screen dispatching the correct projectile to defeat the oncoming hordes. Only the correct shot will take down the enemy making for some very tactical shooting. Thankfully its possible to use tactical freezes to be able to get to grips with who needs what projectile dispatching, though these are strictly limited. Very pleasurable (at least at first) to become highly addictive.
