The my Doom Weapon Mod replaces the pistol, shotgun, machinegun, rocket launcher, pipe bombs and shrinker in Duke with the Doom pistol, shotgun, chaingun, rocket launcher, plasma gun and BFG-9000 from Doom. The HUD weapons and the weapon sprites have been changed as have the weapon sounds, effects and projectiles. Also the HUD itself has been replaced with the one from Doom and so have the med kits.
