5 maps, again... all great maps (some of the best of the M1s), but again, the textures will hurt your eyes. (They're still fun, though...we hit 12 dpm again on a 2 player game on Cylinder...)
3 levels. These didn't thrill me as some have... and Circle Jerk has a bit of smearing if you're looking at the platform next to you as it moves (somewhat unavoidable, given the Marathon engine). Still fun, though...
