X-COM - Mutons in human fashions

Archons appear as enemies but I haven't seen what they do in a civilian capacity, if anything. Andromedons appear to have found a niche in heavy lifting and combat sports; you don't see them as actual civilians in gameplay but you can encounter a boxing ring with two dead Andomedons in the ring during some missions (presumably the crooks you're there to apprehend killed them).

Berserkers probably had to be put down. They seemed more like mutated animalistic monsters than regular mutons.
