DM-Wizard is designed for up to 8-players and seems to play fairly well even though the author, FrameR-A-T-E aka Adam Coggin, warns of slowdowns in his Readme file.
The architecture is comprised mostly of 4-sided towers, ramps, and lots of water. The structure sets in water, and waterfalls abound (coming out of nowhere), plus a splash here and there on the floor. (No pun intended. Well, maybe a little punning.)
The bots make use of the facilities, and the items were not overly done. The Keg-O-Health and Shieldbelt were somewhat difficult to own, which helps to please those looking for a challenge.
A custom texture package is included, augmenting the wood and stone default game textures. I noticed some texture quirks here and there, but you'll probably be too busy bloodying up the place to notice. An ugly, orange sky looms overhead, with 90 m.p.h. clouds that make you dizzy if you stare at them long enough.
Lighting added some much-needed color, while music and ambient sounds chimed in to round out the level.
