Works great Wakka! Had allot of fun playing it and it's a great custom map! Just the navmesh needs to be worked on a tad bit more, and I encountered this odd glitch where, I knifed a zombie then went into prone in the robot room where the zombies jumped up and I... fell under it? I was pretty much invincible there and had to die to restart because I was stuck under the ledge. And about the navmesh, I'm sure you're aware of it as I watch your videos I think you mentioned it in one of them that there's no navmesh under the train in the water and on the steel above it, I uploaded a screenie as well.
