Kill Them All II is a short but intense scenario for Marathon Infinity. It is a collaborative project, wherein the challenge for each mapper was to make complete, high-quality levels with 100 or fewer polygons.
KTA2 features 11 maps from five mappers: screamingfool, Drictelt, Hangar96, shadowbreaker, and myself. It's difficult, with loads of carnage -- very fun.
