The Left 4 Dead Blog outlines this week's new Left 4 Dead 2 mutation, Lone Gunman. No grassy knolls to hide behind here, as word is: "You and your Magnum against the deadly horde and Boomers. So you have your Magnum pistol and… well you do have your Magnum pistol. You better be counting bullets because four swipes by a common and you are dead. Getting boomed? Forget about it." Steam News announces the mutation is live, and another update has word on a bug fix in the zombie shooter sequel, saying: "Fixed versus servers sometimes shutting down before both teams have fully connected."
