You should also add how you should kill the Scientist, the easiest ways so far are, using a pack-a-punch gun, saving a instant kill/death machine or on one player get a quick revive, when you go down you will have akimbo pack-a-punched something and you can kill him really quickly, also include locations to the pack-a-punch machine for those who dont know. Aswell as power locations..
Hope i helped
