The third add-on for Left 4 Dead 2, a four-chapter campaign called ‘Cold Stream’, has been released today for the PC version of the game (through Steam). Xbox 360 owners will have to wait a little longer, as Valve states it is “working with MS on a release schedule“. As usual, the PC version will be free, while the Xbox 360 one will set you back $7.00 USD (560 MS Points).
Cold Stream distinguishes itself from previous campaigns by having every single one of its four chapters end on a ‘gauntlet’ event (think ‘The Bridge’ from The Parish campaign in the original game).
The final chapter, Cut-Throat Creek, is a panic event through the entire level.
The ‘Cold Stream’ update also comes with ports of Death Toll, Dead Air, Blood Harvest and Crash Course from Left 4 Dead, so now you can play through them in the sequel and see how Coach handles zombie airport security.
