Valve has shown off a new poster for upcoming Left 4 Dead 2 DLC: The Passing, and it features a rather revealing tagline.

There’s still no news on when the add-on will be released, though March has been mentioned before.

The tagline is vaguely spoilerific, so don’t read on if you’re bothered about this kind of thing. The tagline reads “Nobody Survives Forever”…

The Passing goes into what happens after the events of Left 4 Dead 1, showing what happens when the survivors from both games bump into each other.
