Thanks to Hellbent for some slight but much-needed modification.
Updated with some last-minute changes.
Screenshots are a little outdated. There's a ledge with a medkit in the area in screenshot 3.
Don't know why it doesn't work, but it seems not to work for s3 servers only.I'm not really familiar with how s3 works, but it's not http, so I'm not really surprised.
Updated. Really wish the image linking systesm wasnt retarded.
Really? Excellent. I've added to it a little since uploading this, obtaining the blue and yellow keys is now a little more complex than "go into locked room with another key".
One hell of a map! Absolutely perfect! - both architecture and gampelay-wise.
I'm definitely voting this one in.
