Set in the immediate aftermath of the zombie apocalypse, Left 4 Dead's survival co-op mode lets up to four players blast a path through the swarming zombie hordes and terrifying mutant monsters. Guide your survivors across the rooftops of an abandoned metropolis, through rural ghost towns and pitch-black forests in your quest to escape a devastated Ground Zero crawling with infected enemies.
Valve spills the beans on custom content for the popular game, Left 4 Dead.
Posted by Henley on Jun 20th, 2009
Some more news has been released via the Left 4 Dead blog about how exactly the new user created custom content is going to be implemented into the game. This will all be done by using an add-on platform and the new VPK file system.
It's nice to see that Valve has decided to make installing and playing custom content as easy as possible, and with the update to the matchmaking system if players do not own the VPK files needed for the custom campaign then it will be offered to them to download.
On my quest for answers on what exactly the VPK file is I managed to find that everyone's favourite Source SDK development program GCFScape now supports VPK files too. It turns out VPK is just a another variation on the GCF file that populates most Valve games, so being able to use others work looks like its possible, not sure what the copyright would be on that either. The last piece of news from this update is that as of this patch going live the L4D Authoring tools/SDK will go live as well. I would still like Valve to give modders access to a full SDK for L4D as the director in modding hands could see some great things be developed, but as of right now it does not look like it's going to happen. A shame really.
