Nuclear DOOMmare

DOOM's arsenal breaks into Nuclear Nightmare. You play Nuclear Nightmare as usual, but DOOM's weapons, pickups, sounds and music are in it, all read from your own DOOM + DOOM II while you play.

What's in it

• Seven DOOM weapons: Pistol, Shotgun, Super Shotgun, Chaingun, Rocket Launcher, Plasma Rifle and the BFG 9000. They use DOOM's sprites, firing frames, muzzle flashes and sounds, and they deal real damage to Nuclear Nightmare's creatures.
• DOOM pickups across the island: shotguns, chainguns, clips, shells, rockets and cells, drawn as the original DOOM sprites.
• Two modes, picked when the match starts:
  • [Y] DOOM mode: you start with the Pistol and 50 bullets. The rest of the arsenal is out there.
  • [N] Normal mode: no starting gun. DOOM's weapons and ammo are loot you have to find.
• DOOM music: Nuclear Nightmare's ambience, search and chase music is swapped for The Healer Stalks, Shawn's Got the Shotgun and At Doom's Gate.
• DOOM.EXE: walk up to any facility computer and press K. Real DOOM (E1M1, from your DOOM.WAD) opens on its screen while the island keeps going around you. Clear E1M1 to earn the BFG 9000.
