A tight, pillar-filled level, with a small open area in the center and a pair of raised catwalks. Lots of attention to lighting detail, to great effect. Not the lowest-poly-count map out there, though... a bit slow on older machines. (Okay, you need a fast ppc to run it.) Quite nice as a solo practice level, due to the repeating baddies... definitely worth the download. Not clear what's new in this version... possibly tweaked weapons placement?
