Half-Life Bubble Mod

Bubble Mod is a server-side-only modification for Half-Life. Players do not need to download or install anything to participate—simply join a server running Bubble Mod. While these servers are now rare, Outpost 42 still hosts Bubble Mod for fans of this classic Half-Life gameplay.

This mod significantly alters the standard Half-Life experience, making it more challenging and skill-intensive:

High-damage weapons are weakened for balance.
Critical gameplay exploits (like tau/grenade/RPG binds) are countered.
New weapon modes and runes encourage team play and variety.
These settings can be enabled/disabled depending on the server.

How to Install Bubble Mod

Ensure you have a working HLDS server installed.
Back up your original valve folder (e.g. copy it to valve_bu).
Download Bubble Mod from the link above and extract it into your valve directory (e.g. C:\hlds\valve on Windows).

Next, configure Half-Life to run Bubble Mod instead of the default game by editing the liblist.gam:

//gamedll "dlls\hl.dll"
gamedll "dlls\bubblemod.dll"

Linux:

//gamedll_linux "dlls/hl.so"
gamedll_linux "dlls/bubblemod.so"

Note: If the server fails to load, try renaming the Bubble Mod DLL/so files to hl.dll or hl.so and update liblist.gam accordingly.

Save liblist.gam and start your server. If installed correctly, Bubble Mod will load. Test it in-game — for example, right-clicking with the crowbar lets you throw it!

Configuration

Once Bubble Mod is running, customise it via bmod.cfg in your valve directory. Options include enabling/disabling runes, tweaking weapon settings, and adjusting gameplay balance.
