1. Download Options
GnollHack's Linux version has the following download options:
- Steam — Recommended download option (also covers the Steam Deck).
- AppImage — A single self-contained file available on GitHub that you can use without Steam.
1.1. Steam
1.1.1. Auto-Update Can't Be Disabled
You can't disable auto-update in Steam, but if your saved games become invalid, you can revert to a compatible version of GnollHack as follows:
- Contact the GnollHack Dev Team and ask that the previous game version will be made available. They will give you a code.
- Go to GnollHack Properties in Steam.
- Go to the Game Versions & Betas tab.
- Enter the code to Private Versions and click Check Code.
- The requested game version should become available for choosing.
1.1.2. Steam Platform Features
- Save File Synchronization — Sync your saved games across multiple PCs.
- Revert to Old Version — You can revert to an old version using the Game Versions & Betas tab in the GnollHack properties in Steam (see above).
1.2. AppImage
- The AppImage package has the .AppImage extension (
GnollHack-<version>-x86_64.AppImage). - It is a single self-contained file that runs on most 64-bit (x86-64) Linux distributions without installation or administrator rights.
- Install and run the game using these instructions: Installing the AppImage on Linux
- The AppImage version of the game doesn't have built-in auto-update. You update it manually by downloading a newer version (or using an AppImage updater).
2. System Requirements
- A 64-bit (x86-64) Linux desktop with a working graphics driver (Mesa for AMD and Intel, or NVIDIA's driver). X11 and Wayland desktops both work.
- Sound through PulseAudio or PipeWire, which most desktops use.
- In-game web pages, such as this wiki and Gnoll Overseer, use the Chromium engine built into the game, so no web browser components need to be installed.
