This map had real potential... level construction is fun, the new hunters give you a serious adrenaline rush, and the potential for future maps in the series is great... but it's too easy to lock yourself into a dead end. (I did it.) Most of the switches have delays... so it's easy to close a one-way door and still get through it, but you won't be able to come back. Oh, well... If you're careful what you open (and close), you should have fun.

As the title implies, five levels. These are generally large, wide open, rambling levels, mostly well-lit. Aliens abound, and weapons range from plentiful to meager. A cool trick I don't think I've seen before was used on Doors of your Mind.

This is one big map. Some nice lighting effects, and sound is used well... but with fewer than about four, you'll feel lost. Textures are nicely spread out... you can pretty well place yourself by the walls around you. (This is a good thing, on a map this big...) A few nice secrets, for those with the time to find them.

A whole bunch of platforms that are invisible, except from above... set in space. Really tough to figure out where your enemies are... especially if you play with the motion sensor off. There's a catwalk around the outside for those of you who get queasy.
