Easter Eggs

Doom reference

On the last level before you go through the portal to fight the boss. Their is a stone tablet somewhere in the last room. If you look at it you can see the picture of the original Doom cover.

Special PDA from the ID developers

Right at the end of the game, just before you fight the final boss, as you are walking through the underground hall with all the fire and brimstone there will be a small space in one of the corners you encounter that you can duck under and there will be a brick with the ID symbol printed on it. Press action on the brick and it will open the wall allowing you to get the PDA of the ID developers thanking you for playing the game.

Super Turkey Puncher 3

Go to the first level in Co-Op mode and proceed through the level until 'Command Access Junction'. There you can find two Super Turkey Puncher arcade machines made by 'Nabcon'. On the screen is the face of the original Doom Guy and also makes the same faces when you punch the turkeys. First player to 3000 points wins.

Hidden movie

Once you kill the first scientist who gets turned into a zombie, look at the main control panel. One of the screens right near you should be blinking red. Click on it to watch a little movie.

Machine Gun in Underground passage.

After you get you shotgun and reach the security area, go in side and unlock the door. After the door is unlocked, on the same screen, look at the botom of the screen and click on one of the 2 choices. One should bring up the lockers, showing one is locked and the other open. Click on the one that says locked. Now head out into the elavator room and kill the imp that jumps down. Look at the lockers now, the other one is now open, allowing you to have the machine gun and more shotgun ammo. (Note: After you grab all the goodies in the locker, an imp will come out of the door you just came out of to get the goodies.)
