Vietcong Easter Egg - Zombie

In your very first mission, the one where you arrive in Nui Pek, go directly to your bunker and try to open your door. It won't, but keep on trying. The tenth time you try to open the door, you'll hear someone's evil laughter; the thirteenth time, you'll get the grenade launcher. Keep on trying to open the door and a VC zombie will approach you. His arms will be in front of him (like he's sleepwalking), his head cocked to one side, with his eyes all going mad. Voodoo chile, baby ! Oh sure, go ahead and try to kill him. You can't. He will follow you everywhere you go. Also, you can now access the jeep and drive around the camp.
