w00t! L4D is finally getting a decent content patch which is going to add Survival Mode. This new mode sets your team in a locked down area and spawns waves of infected. As the horde and specials continue rampaging through the level they will open up new rooms that have items and weapons. Apparently this new mode is going to be very difficult and Valve expects short games of massive epic pwnage. awesome! Check the link below for all the details:

Also, I'm definitely going to be on tonight, hopefully immediately after the patch is released. Hop on vent and hopefully we can get a couple teams of 4 to play together.
