[Edit] Qwertyus has brought to my attention that a bug with the engine could cause problems for some people due to the dead scientist model I had used. He was nice enough to give me a fixed version which shouldn't cause it, so the file has been edited to include it. For some reason TWHL doesn't seem to want me to update the download, so the fixed version can be downloaded here: https://www.mediafire.com/?69as20pt2aae4da
Seeing as he was willing to extend the deadline a little, I thought I had better make some nicer surroundings rather than just having it in a bare room. Whether that should count towards the tree decorations is up to CT to decide.
I also made use of some mapping techniques in this map that I hadn't really used before, which is nice.
