Did you know? Update 1.4.1 has just released today (26th March), which includes Crew Skins as one of the newly added features. When applied to a crew member, these skins will alter his/her appearance accordingly.
The skins do come with their own personas as well, which makes you wonder: are your crew members just wearing a different skin (literally), or have they been banished to another dimension for the time being while another entity takes its place? Some questions are better left unanswered...
