The Passing to include "new game modes"
Left 4 Dead 2 add-on sounds substantial.
Valve has said to expect "new game modes" in The Passing DLC for Left 4 Dead 2, which is now listed as "spring" rather than March.
That's according to an update to the Left 4 Dead blog which lists some of the pack's new features.
These also include a "Wicked Witch Bride", an M60, a golf club melee weapon and "The Fallen Survivor".
Plus there's the chance to rendezvous with the L4D1 survivors. A separate L4D1 DLC pack will be released later that shows some of those story elements from the first game's perspective.
