With the release of Left 4 Dead 2
just on the horizon, Valve is making good on its promise
to keep up support for the first game ... on Steam, anyway. Valve has flipped the switch
on a new update, which adds Team Versus 4 on 4 competitive matchmaking to the mix -- something Valve has been promising was in the works since April
of this year.
The update also fixes a pair of bugs in the game, dealing with a nasty game-crashing glitch that would occur as a result of a certain 'Crash Course
' achievement (there's a joke in there) being unlocked and an issue where bots and computer-controlled special infected were being reported in the 'View Game Info' screen.
