Hmm... L4D dlc a little underwhelming. I was hoping that they'd announce a new campaign. It will be free DLC for PC, not sure about x360.

Also, did anyone watch the l4d footage in the video? Those were some awful x360 players.

Hopefully free for 360 too!
Extra versus levels were expected really.
Horde mode should be good.
But yeah nothing much new otherwise!!
Still I'm really looking forward to this whenever it gets released!

Can't wait for the Left 4 Dead DLC.

They need to release the patch to fix some of the issues in versus. They have already released a couple on the pc version. I look forward to the survival mode, but enabling the other 2 "maps" for versus should not cost much.
