What will be your possible reaction when you realize that you are in the ship infested by unknown and hostile creatures? You would probably scream and cry for help. But let me tell you, you are your only hope and so the only choice for you is to use the available weapons and whatever little skills you possess to eliminate each of the evil ones. Your main objective would be to survive and keep going neutralising them all, deck after deck. Use WASD keys to move and use the mouse to aim and shoot. There are useful things that you should collect while exploring the areas always expecting to encounter the evil ones who will show no mercy whatsoever.
