This is now up to six maps (although two are just the same map with different net options...). One is unstable on 68K macs-use the Ignore Zero Divides program to get around this. A pretty nice mix... small, medium, and large arenas, some nice twisty areas, a bunch of enhancements to take advantage of the new M2 features. Bunch of tweaks (texture alignments, etc.) Now comes with three physics models which make the alien weapon a bit more deadly...
