Conflict: Vietnam Cheats (Xbox)

At the beginning of the level, get all the ammunition in the weapons room (to your left at
the very start). Then, move on to the Major. When he tells you to go to the bunkers, take
Ragman and the Doc and crouch down next to the Major. Then, take Junior and put him in the
first bunker to your right and up the stairs. Then, take Hoss and put him in the next
bunker down. Whenever someone dies, the Doc will heal them.
