I don't get Viper design... the concept art start looking like they wanted some sexy scaly lady but when they go to the face they went all SUPRISE MOTHERFUCKER and gave her a hideous snake face.

Or maybe it's the creator fetish?

Still, I like the class because it remind me of the original Snakeman, which was one of the few classes not present in the XCom 1. Yeah, I know about the Thin Man but they don't count because they looked nothing like the Snakemen.

I'll probably try to make a cute Viper for the next cheesecake on my patreon.
