Mods
Mods (often called modlets) go into a Mods/ folder in the server root, with one subfolder per mod containing ModInfo.xml. Upload the mod folder, restart.
- XML-only modlets (balance, recipes, loot) run server-side; players need nothing.
- Mods with new assets (custom models, sounds, UI) or DLL code (Harmony patches) must be installed on every client too. The mod's page says which.
- Overhauls (Darkness Falls, Undead Legacy, War3zuk) are full packs that both sides install; expect 12+ GB RAM.
The mod load order is alphabetical by folder name; prefix folders with numbers if order matters.
Updates
AUTO_UPDATE=1 checks Steam on every start. After a game update, restart from the panel. Mods that touch XML usually survive minor updates; DLL mods break on major ones (each new alpha/version) until the author updates. Until then, disable them by moving their folder out of Mods/.
Experimental branch
To run an experimental build set SRCDS_BETAID to the branch name Steam shows (e.g. latest_experimental) and reinstall. All players must opt into the same branch in Steam.
