The Firearms: Source Website has the debut release of the Firearms: Source modification for Valve's Source engine. Here's a portion of the description that conveys what this is all about: "Wondering what some of the key features of our mod are? Firearms: Source is a fast-paced, quasi-realistic, action-oriented, warfare-centric modification for Valve's Source engine. FAS doesn't keep you waiting around to respawn or running forever to get into the action; our whole focus is on keeping you in the midst of the most brutal and violent firefights you've ever seen in Half-Life 2, period." Thanks Elden.
