Pick up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people, people he cares about, are counting on him.
What started out as a gimmick, quickly became one of the most popular maps for garrysmod. I completed it in January, 2010, and it's still has the most downloads of any non-rp/build map. It was originally made for a multiplayer mod, known as Zombie Survival, within garrysmod. As of now I'm still uploading old maps in order to build up my Moddb portfolio, there are videos of other maps on my Moddb profile if you're interested, and my youtube channel (Modeststudios)
