While having the code for Half-Life 2 out in the wild before the game was finished wasn’t a super positive experience for the team finishing the game, it's pretty cool to see what the mod community could get working with that unfinished codebase. I do remember there being a pretty significant, and somewhat underground, mod community that was working off of the Half-Life 2 source code leak from 2003. What's it like being a citizen under the oppressive thumb of the Combine on a Garry's Mod roleplaying server? We went undercover to find out.Įrik Johnson: The specific point in time is a little tricky to pin down.
