Experienced level design is very evident here. An impressive map with solid gameplay and an original theme which is consistently applied throughout. Texturing and lighting are excellent and there are some original sound files which really add to the atmosphere. Item placement is superb. A faultless map.
This map is definitely a keeper, though you will need 8 or more players to really enjoy it.
Update: 1st April: ha ha
Update #2: A short demo is available with about 30 Nightmare bots in dm_68 format (supports version 1.32 of Q3A) or with 32 bots in dm3 format (original, unpatched Q3A release version - thanx Zero Cool!).
