'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...

That is indeed an impressive changelog. Looks like you listened to all the feedback, I like that :) I can't wait to try this in versus, Valve needs to support campaigns like this so there can be more versus games.
