Firearms: Source is a team based first person shooter, rooted in the traditions of the Firearms mod for Half-Life. Firearms: Source brings the best aspects of Firearms to the Source engine, and then takes them a step further. You'll see a host of familiar weapons and maps, but you'll find the streamlined game play to be faster, focusing on aggressive, skilled play. From nearly the moment you spawn you can expect to be engaged in furious action.
Good mod. Lauch of the first public version was awesome. Some bugs and some one map was poorly balanced. Most of these issues has been already fixed as of now. An old school Firearms player should like this mod. The only downside is that nowadays the player count has dropped a bit drastically.
