Indoor HL2DM map for 2-8 players.
Four rooms on two floors around an open courtyard-like center
under a glass dome (or spire...).
Specials:
Motor driven rotating door (with switch) - you can go through it while it's running, if you're lucky...;-)
In the center: A huge motor driven fan (with switch) mounted below the ground, blowing you up the spire to a circular tire shaped platform with goodies (like rocket launcher and crossbow).
Around the fan place: A "moat" like water barrier. There are two bridge plates - but they can be pushed or carried way!
