Dumb antagonist idea: sewer gators

[Noah Buttes]

Personally, I don't feel that the sewer aesthetic fits SS13 in any capacity. We could keep something that utilizes the same gameplay concepts (scooting around vents, ect.), but just has a more space-like appearance to it.

You could just have them be highly mutated abominations warped into their current forms as part of a syndicate bioweapons research project.
