Campaign/Story Creation
This is currently a work-in-progress, but will be documented soon. Here are the current specifications:
1. Whatever Half-Life 2 uses already works
2. For transition support, your map must have an info_landmark, trigger_transition, and trigger_changelevel. Check out the Valve Developer Wiki for more information
3. Information about round setup and other basic rules

Recent gmod updates have fixed several issues with the gravity gun, including mega mode during the citadel parts. Do you think we could see that being reworked to use the engine variant instead of the lua version? I just noticed that it creates a projected texture for everyone that's currently using it, and it lags my game out hard.

Far as I can tell no I think it's dead which is very unfortionate cause that means pretty much both gamemodes for Hl2 levels are well dead. About the only coop gamemode that is still updated is the one for Hl1.
