Plazma Burst: Forward to the past

The whole game is not simple at all times. Scientists have sent you to the past to get things in order, but things have gone terribly wrong and now were back for shooting action. The story is pretty stupid but the game is better and thats what matters. It is a kind of a platform shooter with cool weapons, good gameplay and very clever AI. Move with W, A, S, D and aim and shoot with the mouse. You can improve your equipments as you pass through levels and then continue fighting.
