Duke Nukem 64 Cheats

Dark Duke

Start a game in single player, co-op, or deathmatch mode. Enable all codes except for invincibility. Arm Duke with the plasma rifle or gun. Charge the gun to full power, then shoot it near a wall next to you or shoot the charged blast on the ground. Die, then quickly press Start and enable "Invincibility". REMEMBER: This must be done before the "Press Start" message appears. Resume game play as a darker almost ninja-appearing Duke.
