Chimeras definitely won't be shooting. The problem is that there are no textures for the upgraded chimeras. In general, right now, only the Pseudogiant and Pseudodog are ready in the form I want them to be. The Bloodsucker, which has three texture variations, has mismatched texture maps, and I don't know how to edit them.

P.S. I just remembered... will the Swamp Doctor be included?
