The Thing Cheats

Beat the second boss
You can get the Medic to follow you in by pushing him up against the big door then telling him to follow you and then open the door.

You don't need the medic just get the grenade launcher from behind the wooden boxes by using a frag grenade and use the flame grenades you will get with the launcher to burn the boss up.

Keeping Williams
On the level where you are chasing the norwegian with radio and he locks himself in the building, well you know how when you run into the other building to get the key to the other building and Williams turns into the thing? I have a solution! Instead of running into the building go to the door an when Blake says "It reaks of fuel here it must be all over the place" throw a flare and grenades at door and it will blow up! It will also save you alot of health. And then you go in and get the key and you get to keep williams the rest of the level. But dont get in the building or he will change into the thing!
