Modern Windows (x86) port of the ZGloom engine that reimplements the classic Amiga FPS Gloom and its successors for contemporary PCs.
Play Gloom, Gloom Deluxe, Gloom 3 and Zombie Massacre on Windows with a fixed renderer, widescreen support, post-processing overlays and save/load position – while staying faithful to the original Amiga gameplay.

ZGloom-x86 is the Windows edition of the ZGloom source-port family. It focuses on a clean software-style renderer, extended in-game options and subtle post-processing while preserving the original feel of the Amiga release.
For other platforms, see the companion projects ZGloom-Android, ZGloom-Vita-Vita2D (PS Vita / PSTV) and ZGloom-macOS.
Gloom was a 1995 Doom-like first-person shooter from Black Magic Software for the Commodore Amiga. It featured very messy and meaty graphics and required a powerful Amiga at the time (an A1200 with 030 CPU was still on the low end). The engine later powered several related games and successors, including:
- Gloom Deluxe / Ultimate Gloom – enhanced graphics and effects
- Gloom 3
- Zombie Massacre
- Various full-game conversions of other 90’s Amiga titles
ZGloom is a modern reimplementation of this engine.
-
Modern source port of the Amiga Gloom engine
Runs the original Gloom data files on modern Windows PCs (x86) using the modern ZGloom C++ engine. -
Supports multiple official games
Play Gloom, Gloom Deluxe / Ultimate Gloom, Gloom 3 and Zombie Massacre (plus selected mods where available). -
Built-in multi-game launcher
If more than one game or mod is present, a simple launcher lets you pick what to play at startup. -
4:3 and 16:9 display modes with FOV control
Switch between the classic 4:3 Amiga look and a widescreen 16:9 mode and adjust the field of view to match your display and taste. -
Improved renderer, lighting and effects
Uses the fixed ZGloom renderer with cleaner perspective, fewer glitches and subtle lighting tweaks, including dust particles, dynamic muzzle flashes and colored floor reflections under projectiles and weapon upgrade orbs. -
Atmospheric post-processing overlays (optional)
Enable vignette, film grain and scanlines for a more gritty, CRT-style presentation without changing gameplay. -
Save/Load position and extended options
Save your in-level position (including health, weapon and ammo state) and tweak many more options than in the original Amiga release.

Get the latest Windows (x86) build here:
Each release contains the ZGloom.exe and required libraries.
Game-data is included.
Gloom was made freely available by its developers.
Download the game and extract it somewhere on your drive.
Then simply double-click ZGloom.exe to start the game and the launcher appears.
Keyboard controls in ZGloom:
- WASD – Move and turn
- Left Alt – Strafe
- Left Ctrl – Fire
- Left Shift - Run
- F1 – Skip level
- F12 – Toggle fullscreen
- ESC – Pause and open the in-game menu
The extended menu offers more options than the original game and port.
You can change values with the left/right arrow keys (for example for fullscreen, vignette, film grain, scanlines, and other display options).
This repository is currently set up to be built with Microsoft Visual Studio 2026 on Windows.
Linux, macOS, CMake- or make-based builds are not tested at this time.
The project is structured around the MSVC toolchain and Visual Studio project/solution files, so the recommended workflow is:
- Install Visual Studio 2026 with the “Desktop development with C++” workload.
- Clone this repository to your PC (working SDL2 and SDL2_Mixer are included in this repo).
- Open the provided Visual Studio solution (or create a new one and add the sources from this repo).
- Select a configuration (for example
Release/x86) and build the solution. - Copy your original Gloom game data next to the compiled executable as described above in the Getting Started section.
If you want to experiment with other platforms or compilers (e.g. gcc/clang on Linux), you will currently need to:
- create your own build system files (CMake, Meson, custom Makefiles, etc.),
- and handle any platform-specific fixes yourself.
Clean, optional contributions that add a portable build setup without breaking the existing Visual Studio workflow are very welcome.
This repository is a fork of Swizpig/ZGloom.
The goal of this fork is to:
- Fix the renderer using improvements from the PSVITA SDL version
- Enhance menu navigation and keyboard usability
- Add post-processing overlays (vignette, film grain, scanlines)
- Provide a polished Windows (x86) build with its own executable icon
If you enjoy retro Amiga FPS games and want a modern Windows port of Gloom, this fork aims to be a convenient, visually enhanced option.
The licensing situation around the original Gloom sources is a bit unusual:
The Gloom source release says only the
.sand.bb2files are open source, but the Gloom executable bakes in some maths lookup tables (generated by the.bb2files), bullet and sparks graphics, and the title screen for Classic Gloom.
This fork follows the original release and does not add the Classic Gloom executable assets (title screen etc.).
Instead, it uses alternative imagery such as the Black Magic image.
