"Damn I'm Good" difficulty level God mode:
Begin a new game at the "Come Get Some" difficulty level. Enable the God mode cheat code and begin a new game under "Damn I'm Good" difficulty level.

Opponent viewpoint:
Begin a modem multiplayer game and enable recording on the options screen. Press K during game play to view the game from your opponent's view point.

Third person view of players 2 to 8 in demos:
Begin a game and hit [F7]. Press [Esc] and select "Quit To Title". You will now see players 2 to 8 from a third person view.

Hint: More guns at final Boss:
If you have a jet pack, fly up and destroy the beer blimp. Guns and health will scatter on the ground, allowing the final Boss to be killed easier. Note: One of the best weapons to use against it is the Devastater.

Glitch: Floating dead:
Enable the dncornholio code and go to the cogs on level 3. Go behind them and continuously run into them, which would normally kill Duke. Keep doing this and you should appear above the cogs, dead but floating and still being able to move, shoot, and fall. Jump to return to normal again.
