Left 4 Dead 2: The Sacrifice
So a new DLC came out. It's basically a new short campaign that ends with one of the original survivors sacrificing themselves so the other 3 go on. You meet up with the 3 survivors on the bridge if you have The Passing. They also reboot the No Mercy campaign, just adding everything that was new in L4D2 (chargers,jockeys,melee). You can also get it for L4D but you won't be able to use the additions from L4D2. It's 560 points. I'll let you know how it is when I play it later.
