Tyrant

   Tyrant is the very last boss in the game. A HUGE monster created by a large ammount of the T-Virus. Very pwerful and fast. Has huge sharp claws and when it swipes you it takes your health down quite a bit. He runs very fast and swipes his giant claw at you. On the helipad i suggest you run in a circle around him but not to close or he will swipe you. Brad will throw you the rocket launcher to kil him. In the lab i suggest you use the magnum and when he walks over the wires on the floor shoot him with it.
