Super Password!
Enter the following password: W93M 7H2O BYCO PSVB. This code will give you 100 health, 200 armor, all the weapons, full ammo, the backpack, levels 29-31 finished, and takes you to the last level. Also, it gives you three pentagram items that make your laser three times as powerful as the BFG9000. You will be able to kill the last boss in four seconds. The three pentagram items also let you use the three switches in the last level (closes the gates that spawn the monsters), and the laser now shoots faster and stronger.

Taunts
After you've died in Doom 64, text-style taunts will appear on your screen direct from the Midway developers. Wait about 25 seconds after dying to see them. Some of these "taunts" are very amusing.
Getting to "Level 32: Hectic
To reach Level 32: Hectic in Doom 64, you must start a new game. Go through Level 1: The Staging Area, and destroy ALL the barrels, except the one to the right of the start. There are a total of 10. Remember the secret areas, the room with the exit, and the alcove in the hallway leading to the exit. Be sure to collect the Soul Sphere and Combat Armor for a better chance at surviving later on.
Once you've destroyed all of the level's barrels, take the teleporter that you can access from the secret area behind the Blue Door. When you reappear, destroy the barrel ahead of you on your right and enter the door behind you. A secret area will temporarily open on the left wall that leads to Level 32: Hectic.
Walkthru for Obtaining the Three Keys in "Level 32: Hectic
At the beginning of Level 32: Hectic, enter the door to the right for the Red Key. Once you pick it up, you'll be dropped into a room with three Arachnotrons. Quickly go left or right to get the Rocket Launcher. Destroy the Arachnotrons and return to the door that leads to this room. Beware of the crushers that come down from the ceiling, search the wall to lower it and let it raise you back to the main room.
Enter the door on the other side of the room to get the Blue Key. As soon as you get it, run back to the door you entered from. The ceiling will crush you if you stay in the alcove where you find the Blue Key. Four Hell Knights will appear and the door you came in from will be closed. Destroy them with your Rocket Launcher to be able to leave the room.
Enter the door on the left side of the room, at the opposite wall is the Yellow Key. The floor rises in different parts of the room, and darts will fire from the faces in there. Try your best to avoid damage while getting the Yellow Key.
Exit the room to return to the start. Directly across from you is a switch you will now be able to access. Having the keys, you can now remove the bars and press the switch to exit Level 32: Hectic.
Once this is completed, you will gain access to the "Features" cheat menu in the Options. In that menu, you will find the following items:
1.Warp to Level: This is the ONLY
way you can access Level 25: Cat and Mouse, Level 26: Hardcore, and Level
27: Playground. Three secret levels in between Level 24 and 28.
2.Invulnerability: Turn "God Mode" ON/OFF using Button A or B.
3.Health: Use Button A or B to restore your health.
4.Weapons: Use Button A or B to get all weapons and full ammo for each.
5.Map Everything: Turn Map Everything ON/OFF using Button A or B
