After being rescued from the Blood Harvest you find the driver of your rescue vehicle has become infected, and has crashed behind a massive asylum. The Trans-Allegheny Lunatic Asylum.
The main asylum sketchup models is mostly complete. I still have to model the backside. Then more work to import this into Hammer.
Awesome, and you saw my post, that you can import it! Yay! Can't wait for this, i love the skin :D
The only reason I started a L4D map is the SketchUp importer.
