L4D2 - Sacrifice
DFC played their first game of the new Sacrifice campaign last night. It brings together the characters from the original L4D with the map first seen in The Passing
in L4D2. The campaign is pretty short, but the final part is tricky until you work out exactly what you have to do.
No doubt it'll feature at the LAN in 3 weeks time :)
L4D2 - The Passing
The first expansion for Left4Dead 2 has been released this week. Here's a quote from the Steam News article...
The first game add-on for Left 4 Dead 2 (L4D2) brings the original Left 4 Dead Survivors down south for a meeting with the L4D2 cast, while delivering new single-player, multiplayer and co-operative gameplay for the PC and Xbox 360.
"The Passing" features 3 new maps, new weekly game modes (Mutations), a new "uncommon common" zombie class (the fallen survivor), melee weapon (golf club), firearm (M-60), support for infected bot play in Versus, 10 new achievements and more!
This is a free update, and no doubt will feature in our next Friday Night session :)
Left4Dead 2 Details
ShackNews have posted some details of what L4D2 will contain. Melee weapons will include a cricket bat and a chainsaw, and there will be 5 new campaigns. It is slated for release in November, so we'll not get to see it at a LAN until next Easter.
