I recently found this video of a custom map in Left 4 Dead. The map seems to recreate Level 1 from the Legend of Zelda. The map even includes a giant 3D Aquamentus! (derp) Unfortunately this one only has one head, but you can see this creature at the beginning of the video from YouTube user EggyandMe. In an earlier video (here; about 5 minutes in) you can see wall masters moving around the room. They don’t behave quite like the Wall Masters we know and love, but it’s a decent 3D recreation. In addition to that, the traditional enemies have all been transformed into zombies! The video slows down after they retrieve a piece of the triforce, but the earlier videos are rather entertaining. Let us know what you think of this video in the comments.
