Category:1. Installing FA:S

Game Requirements: You must have Steam installed and own any Source engine game that allows you to download the Source SDK Base. If you do not own a Source engine game and are low on cash, you can buy Half-Life 2 Deathmatch on Steam for $5.00.

Installation: First, you must download the game from one of our many mirrors on the Downloads page. After you have downloaded it, you must install the game in your SourceMods directory (..\Steam\SteamApps\SourceMods\). Then you must restart steam if it is currently running, and if everything worked, you will see Firearms Source on your games list. If you are having difficulty, you can seek help in the category Tech Support of our forums.
