The liver is under attack! Only you can stop ominous viruses and turn them out of here! There are 3 missions in the game. At first missions you must reach the liver. In is not easy because enemy is around. At second mission you must kill the boss. But his sequrity will prevent you. The third mission is logical. If you will be very lucky you could see an impressive ending. If you are overbold and persistent I advise you to play this game. The fact not everyone will remain from beginning to end. Good Luck & Have Fun!
