10 maps, some conversions from M2 maps, one extension of a TI level, and a few new maps. All in all, a superb package. Everything from death in small places for 2 to huge, sprawling levels capable of supporting 8. Kree Nakorie, a level I hated when it was first released for M2 (it was so hard to figure out what was going on, and the aliens never gave you a chance to look around) is now a superb strategy level. Wow. Everything tastes better on a Nardo bun. Update fixes a couple of small errors on one level.
