Appearance/discussion of Inferno units.

As Necrofill rightly pointed out, Cerberuses are a mix of reptile and mammal. Moreover, the designers didn't spend much time thinking about its model; they simply took the image of an animal that went extinct 250 million years ago. It was called INOSTRATSEVIA and was a reptilian, mammal-like creature. It's almost identical – a massive tail, legs on the sides of the body, a head... It was about 3-4 meters long, and like a mammal, it was warm-blooded and had a small coat of fur... in short, those who are interested can check this out themselves. I'm not lying:)
they really copied the image; the designers just tweaked it a bit.
