The Passing is up there with the other Left 4 Dead 2 campaigns for fun, horror and great gameplay moments, as you would expect from a Valve release, and is also great value even on the Xbox 360 for the Mutations feature, which brings new L4D2 gametypes, updated weekly.

This adds a new campaign in which the characters of the sequel bump into the original cast of the first Left 4 Dead on a terrible stormy night down in Georgia. Of course, your first port of call for a new custom campaign for Left 4 Dead 2 should be Valve’s own release, The Passing, free for owners of the PC version and available from the Xbox Live Marketplace for Xbox 360 players.
