Duke Meets Doom

Duke Meets Doom, or Duke Nukem 3D Doom II, is a Duke Nukem 3D total conversion that gives the game a Doom II feeling. Aside from a Doom feeling, the TC also gave the game a Shadow Warrior feeling.

Gameplay and features
The game has many weapons taken from Doom and Doom II, but it also took some weapons from other Build engine games. It also featured Doomguy talking. The enemies are from Doom and Doom II, too. However the music isn't from the Doom games (the title screen uses Doom II music, while most of the music in the levels is from Blood using the MIDI format).

The gameplay differs depending on whether or not a specific .con file (titled "doomgame.con" in version 3.0, titled "DOOM.CON" in version 3.1) is activated. With the .con activated, the following changes occur: Without the .con activated, the previously listed changes are not present (the projectile that the Revenant uses will shrink the player, enemies and bosses will use Duke Nukem 3D sound effects and voices, etc).
 * The player starts off with 110% health by default instead of 100%
 * Uzi can hold 400 bullets maximum
 * The Uzi ammo pick-ups give the player 50 bullets instead of 12
 * Double-barreled Shotgun can hold 40 shells maximum (version 3.0 only)
 * Double-barreled Shotgun can hold 20 shells maximum (version 3.1 only)
 * The Double-barreled Shotgun ammo boxes give the player two shells instead of 10 (version 3.1 only)
 * Chaingun Cannon can hold 400 bullets maximum
 * The Chaingun Cannon ammo boxes give the player 100 bullets instead of 50
 * BFG 10000 can hold seven shots maximum (version 3.0 only)
 * BFG 10000 can hold one shot maximum (version 3.1 only)
 * Cursed Expander can hold 120 shots maximum (version 3.0 only)
 * Cursed Expander can hold 100 shots maximum (version 3.1 only)
 * Plasma Cannon projectiles use a new sprite (version 3.0 only)
 * Plasma Cannon projectiles do not bounce off of walls or doors (version 3.1 only)
 * Some of the items are named differently
 * The Plasma Gun/Plasma Rifle functions similarly to the Plasma Gun/Plasma Rifle from Doom in that it doesn't freeze enemies
 * The Hell Knight "statues" (Hell Knight sprites that just stand still and are incapable of being killed) have been removed; Hell Knights appear as actual enemies instead
 * The Doom health bonus and armor bonus sprites are able to be picked up and give the player 1% health and armor, respectively (version 3.1 only)
 * Some of the enemies and bosses have Doom enem voices (the Cacodemon sounds like it does in Doom rather than using Octabrain sounds) instead of Duke Nukem 3D enemy voices
 * The Doomguy's movement speed is slower (version 3.1 only)
 * The mod doesn't use Duke Nukem 3D music and instead uses music mostly from Blood using the MIDI format
 * Revenants use projectiles that function like rockets (although the projectile looks like a Mancubus fireball) instead of shrinking the player

To activate the specific .con file, do the following:

(Version 3.0): Double-click the "dukedoom" application (it is a .bat file), then left-click and drag the "doomgame.con" file into the main .exe.

(Version 3.1): Left-click and drag the "DOOM.CON" file into the main .exe.

Story
The forces of Hell has invaded the Earth, and the Doomguy is trying to stop them. The Doomguy battled his way through demons and zombies, reaching a portal where he confronted the Spider Demon. The Spider Demon is killed, and the Doomguy teleports to a city where the Mancubus is hiding. The city is secured, and the Mancubus is killed. The Doomguy teleports to Hell, where he defeated both the Arch-vile and the Cyberdemon, thus ending the invasion.
