Plazma Burst 2

Great action game. The story isn't so important because you have to save the Earth because of blablabla, fighting blabla. What is so great about this game is its action. In several missions (but the main is multipayer) you must clean the map from all the enemies. They aren't stupid at all and can be very annoying. After finishing some level you get money and possibility tu upgrade or buy new weapons. The price is very high so you have to fight the multiplayer to earn more. The graphics and sound is really great and the bullet-time is fantastic.
