The Left 4 Dead Survival Pack will include a new multiplayer mode called “Survival”. It will also include two versus campaigns. A re-release of the game will see the new content included. If you’re a PC gamer with a penchant for software development and level creation, the SDK for Left 4 Dead will also see a release.
Valve could have milked this, just as other companies – that shall remain nameless – have done with other DLC. Making the new content free might not be smart in a monetary sense, but from a positive PR standpoint it doesn’t get much better than this. Nice one Valve.
