Does for M2 what the OPE did for M1. Allows simple placement of objects (including baddies and bobs) on any level. Add nasties to Bungie's net levels, so you can play them solo! This version adds a much faster searching algorithm and the Marathon 2 default set.
Based on a literary passage that describes a city with a lake beneath it that doesn't go beyond the city's borders. Well done, but can be confusing figuring out where you are.
A fun level with a few good secrets. You can really surprise your playing mates if you find the good teleporters (and the flamethrower). Watch the big guy at the beginning...
A KOH level. Has a pretty nice secret ammo stash... see if you can find it. (No, scratch that-it's pretty easy to find. See if you can access it before someone wastes you.)
Visually very appealing. As far as I can tell, the pistons are for show only (there's no reason to risk getting on them...). Nice little secret alcoves.
An amazingly engaging map-I found myself saying "Okay, just one more try" at least 15 times. Quite difficult, but satisfying to finish. Would benefit a lot from terms
