Well,
here's my first entry. At first I was just going to send this map along to you with several others, but it's probably one of my favorite maps I've ever made... So I decided to release it alone as a "complete" map, as well.
All you'll have to do to is set up the TWHL emblem in the small black box the player is placed in at the end of the sequence. You'll have to enlarge it somewhat into a hallway, and make the emblem transparent with env_renders until the very end. Otherwise, you'll be able to see glimpses of it when the cameras change angles.
Oh, and that other map I was working on is still in progress. This one was just easier to get ready, so I went ahead with it first.
