Crewmate designs in Among Us are instantly recognizable and extremely simple at the same time. That's what adds to their charm! That said, some other designs for the crewmates were toyed with during development, and they're quite a bit different from what we got.
The Among Us team shared a look at some of these designs via an official Tiktok video, and you can see the reveals for yourself above. There's a wide range of options to check out, but most of them are pretty strange, if not unsettling in some cases. I think the team made the right choice with the version we have in game now!
