The game itself tells you what to do. It's just kill kill and kill. The soundtrack is really nice and totally make your imersion great. The weapons are nice (but you can't undo any "mistake upgrade) and you just update your style of playing every time you upgrade it. The graphics are incredible good and if you spend one hour playing this, you will be crying, because the flashs and speed are so intense that you literaly cry. Levels are nice, with some keys around to get, open doors, kill more weird stuffs, get more keys and treasures, points... Everything to level up and upgrade for next stage. If you are thinking to buy or not, i can tell you: Totally worth it.
