'One 4 Nine' is a four-level campaign for Valve Software's Left 4 Dead 1. The setting is the Nevada Desert. The U.S. Army have built a Military base around an ancient 'alien tomb', and after years of trying have finally managed to open it. The four survivors - Francis, Bill, Zoey and Louis - have heard rumors of a fortified safe zone located in the U.S Army's base, but have no knowledge of the tomb, nor what will await them upon arrival...
Great mapping.
The ending was sort of annoying with all the lighting effects and there was not much special leading up to it. It was not well explained. (Yes I know it's from 2001 but how that fit in with the story I don't know how.)
