Agree 100% with @raspatan. This map looks fantastic, but is a little miserable to navigate. Also there are too many items on the map, and the locations are poor. It's like the author(s) didn't spend any time actually playing the map. Some beta testing and feedback from players might've really made this something interesting.

We couldn't find a way to get the invisibility. Anyone know how to get it?

Fun map but lacks more openness. Main rooms are too intricate and full of obstacles. Mobility across the map is impeded by lots of steps, water, pipes, and so on.
Map is a beauty though. Sfx are supernice. Bots play fine. Like it for a while but not a keeper.

Looks like an intersting map. Is it inspired by some Unreal Tournament map?
