Earthshield is a space shooter game where you must protect the earth from invaders with just one tiny spaceship. Press the Triangle, O, Square, or X buttons to shoot in the corresponding direction, and use either the analog stick or directional buttons to move the ship. If you’re feeling particularly bold you can press L or R to increase the number of enemies so that you can rack up more combo points by shooting them in greater numbers. You have three minutes to blast as many enemies as possible unless you’re blown to bits yourself first of course. It’s actually quite fun for the three minutes it lasts, assuming your ship survives that long, but it really is the most rudimentary of old-school shooters and nothing more.
