Just went through it, using Dukeplus, completed it in about less than a hour I'd say (I forgot to check the timer at the end of the level) but then again I love getting lost in maps and exploring. I thought it was good, on other forums I've seen people complain about the gameplay but I personally thought it was well-balanced, with more ammo than needed and enough health to deal with the monsters during the firefights, and it was always pretty obvious where to go next, I didn't have a problem with it (besides spending a few minutes trying to find out how to get into the last building after activating the last switch - I even managed to get into the little room, before I realized I had to stay outside and shoot at it). The fireifights were all good except the last one that was way too easy, I managed to kill the boss by just staying in the main room and shooting RPGs through the door strafing back and forth without having to step outside once. The design was pretty outstanding, excellent in a lot of places, with a fairly unique style throughout. Definitely a hot map I enjoyed playing.
