Other skeleton types#759

I remember you guys having concept art of 2 other skeleton types, or rather just the legs: one with 4 legs and one with backwards knees. What even happened to that? I was looking quite forwards to the idea frankly, I love the mech options right now but I would really like it if I could do some of the other ideas I had in the game. For example, things like this are simply not possible in the game right now. So to put it shortly: What happened to the Rex and Spider skeletons?

Rex and Spider are post 1.0 content which require a lot of work to do. Mainly new animations and creating armor sets for them.
