Inside Xbox has confirmed the price of Left 4 Dead 2’s add-on The Passing: it’s set to cost 560 Microsoft Points when released.

We still don't know when The Passing will be out, though spring is the last date we were told.

We know the DLC will be bringing “new game modes” a golf club and some other stuff.

The Passing shows what happens in the time just after the first game, including a point where the two teams of survivors meet up with each other.
