Thursday Is A Bad Day To Be A Left 4 Dead 2 Infected

Two teams of survivors means twice the trouble for the ravening hordes of infected in Valve's Left 4 Dead 2 this Thursday, when The Passing downloadable content finally shows up on Xbox Live.

Originally scheduled for late March, The Passing's release date was narrowed down to this week last Friday, and now Microsoft's downloadable content schedule narrows that down to the 24 hour period between Wednesday and Friday.

That's Thursday, in case all of these clues I've been dropping stumped you.

As of this writing we're still waiting on official word from developer Valve, but we assume the PC version will hit Steam around the same time.
