Description

Los Santos becomes Hell on Earth. Play GTA V as Doomguy with the classic
DOOM II status bar, Doomguy face and the original weapons – with Doom’s own
fire rates, spread, ammo and sounds – while every DOOM II demon teleports in
around you as proper 8-angle Doom sprites and attacks you, civilians and
the police.

Please note it’s still buggy in places as porting and old game within a new game has it’s problem

FEATURES

Classic DOOM II status bar, Doomguy face, red damage / gold pickup flashes
Fist, pistol, shotgun, super shotgun, chaingun, rocket launcher,
plasma rifle and BFG 9000 – fired the Doom way, with Doom sounds
All 16 DOOM II monsters as original sprites from all 8 angles: zombiemen,
shotgun guys, chaingunners, imps, demons, spectres, lost souls, cacodemons,
pain elementals, revenants, mancubi, arachnotrons, arch-viles,
hell knights, barons, the Cyberdemon and the Spider Mastermind
Demons keep teleporting in around you; arch-viles raise the dead
Doom pickups: stimpacks, medikits, armour, soulspheres, megaspheres,
backpacks, ammo and weapons
Doom health/armour rules, no falling over, minimap with demons as red dots
Doom cheats (IDDQD, IDKFA, IDFA) and an in-game console

REQUIREMENTS

GTA V for PC (Legacy or Enhanced), STORY MODE ONLY
Script Hook V (latest)
Script Hook V .NET (3.9 or newer)
YOUR OWN COPY OF DOOM II (Steam, GOG, or “DOOM + DOOM II”).

No Doom files are included with this mod. The mod builds everything it
needs from your own DOOM2.WAD the first time it runs.
No Doom II? The free, open-source FREEDOOM PHASE 2 (freedoom2.wad,
from freedoom.github.io) works too, with its own artwork.

I made this with AI help (Claude) for the coding. The idea, design, testing and video are mine.

INSTALL

Install Script Hook V and Script Hook V .NET (follow their readmes).
Copy the “scripts” folder from this zip into your GTA V folder
(the folder with GTA5.exe). You should end up with:
Grand Theft Auto V/scripts/DoomHUD.cs
The mod finds your Doom II WAD automatically. It checks, in order:
- the path you put after WadPath= in scripts/DoomHUD.ini
- ANY .wad file in the scripts folder (any name, e.g. “doom2 (1).wad”)
- all your Steam libraries on every drive, and GOG installs
  If it can’t find it, just copy DOOM2.WAD into the scripts folder.
  Where to find it:
- Steam “DOOM II”: …/steamapps/common/Doom 2/base/DOOM2.WAD
- Steam “DOOM + DOOM II”: …/steamapps/common/Ultimate Doom/base/doom2/DOOM2.WAD
  (In Steam: right-click the game > Manage > Browse local files.)
If BattlEye is enabled in the Rockstar Launcher (Settings > GTA V),
turn it OFF – it blocks Script Hook V.
Start GTA V in story mode. The first load takes a few extra seconds while
the mod builds the “DoomAssets” folder from your WAD.
You start in normal GTA. Press F9 for Doom mode, then F10 to unleash Hell.

CONTROLS
F9 Doom mode on / off – the game starts as normal GTA
F10 Start / stop Hell on Earth (red sky, demons teleport in)
F11 All weapons + full ammo (IDKFA)
F8 or ` Open the console (type HELP)
1 – 7 Choose weapon (press 3 again for shotgun / super shotgun)
Mouse wheel Next / previous weapon
Left mouse Fire (hold to keep firing)

Type Doom cheats while playing: IDDQD (god mode), IDKFA, IDFA

CONSOLE COMMANDS
SUMMON [COUNT] e.g. SUMMON CYBERDEMON, SUMMON IMP 5
LIST list monster names
HELL ON / HELL OFF
MONSTERS how many demons roam at once (default 12)
PEOPLE how busy the streets are
KILL GOD HEAL IDKFA IDFA CLEAR

SETTINGS
Open scripts/DoomHUD.cs in Notepad. Near the top you can change:
HudSize size of the status bar (0.7 by default)
ShowMinimap true / false
ShowCrosshair true / false
GunRange how far bullets reach, in metres
Save, then press Insert in game to reload scripts.

TROUBLESHOOTING

WAD message after pressing F9: the WAD wasn’t found, or the file found

isn’t DOOM II (DOOM 1’s DOOM.WAD won’t work – it has no Doom II monsters).
Drop DOOM2.WAD (or freedoom2.wad) in the scripts folder, or set WadPath
in scripts/DoomHUD.ini, then press Insert.
