It’s been six weeks since the infection began; the Survivors have made their way to California and are enroute to an extraction point when their bus crashes at the beginning of an expansive bridge. The quartet are forced to continue on foot without knowing they are heading to a dead-end and ultimately their doom. How long can they hold out?

The Cold Springs Bridge, a survival map available at L4Dmaps.com, has been released. Simply click “Download” and open the containing ZIP file. Once downloaded, installation is as easy as double-clicking the VPK file or dragging it to your left4dead/addons folder.

I’m very happy with the way this has turned out and look forward to building more survival maps in the future. There are many I’d like to thank, most notably: Mobilla, Luigi30, thedaian, Irish Taxi Driver, Rectus, Blazing Ownager, everyone on the Valve SDK forum and everyone in the SDK thread at Something Awful.
