If your are any good at models and coding then you could make a working boss powered by a bot.
With of course looped
Like run over here hit this part, run over there hit that part, he's down now hit him, he gets up shoots off a combination of attacks then he's open for attacks, repeat.
That would make this overkill of awsome.
Best of luck to ya.
(If you can't do this get someone else to do it for ya.)
(I could do the model.)
