Comments on map design:
Unv maps tend to be abandoned or derelict space-stations with combinations of long hallways and twisty passages. Vents and pipes provide places to hide for aliens. They tend to have one or two levels. They can be complex and esoteric, or highly simple. However, there are few maps that deal with other environments. There are a couple maps that do subways. (Metro and Transit). These are generally balanced, as the subway topograph mixes long spaces with twisty. (Transit has problems with the twisty tho). There are also some city maps. Both of them (city-overrun and 1984) have balance issues. (There are too many open areas, the aliens can't get an edge. They are also small. Neither is larger than a block or so. I think that we should have more urban maps. Something along the lines of an alien-infested city would be nice. I just get tired of eradicating aliens from space-stations. We need more different environments.
