Doom 3 single player codes & easter egg's

- In the beginning, when you check in upon arrival to Mars, step behind the guy (who gives you your PDA) and read what he types on his computer. The "supplemental info" is hilarious. (Make sure you set your screen to hi-res and use "zoom" if necessary.)

- Before getting back from the underground, make sure to use the terminal in the security room: it has a hidden menu which allows you to open the display case and get the machine gun.

- Visit the URLs from the PDAs you encounter throughout the game:
These are real web sites, opened by the developers and id themselves. One of them even contains a security code, which you can use within the game to open a storage crate and get an ass-kicking gun.
http://www.martianbuddy.com - 0508

- There is an arcade machine in the kitchen which allows you to play a Doom-inspired game and gain some points of no value.

- At the very end when you get down from the lift and walk down some corridors you come to a T junction. Instead of going right to the end boss. Go left and crouch down. Look for an ID logo on one of the wall bricks and click it (like a lift interface). The wall will open up and you will have a special PDA waiting for you inside.
