Lighthouse of the Dead

Disable your enemies by ripping off their limbs, or explode their heads and swim in the fountains of blood. You’ve got an infinite amount of ammo to fight and three doses of drugs in case your heart fails. Kill four enemies in a row without a single miss and you´ll be healed as a reward for your awesomeness. The only way to survive is to light the beacon, board the ship and leave the damn place. Good luck!
