RTF is a global modification that replaces all towns in the game.

How would I describe it... I think the animation is a bit clumsy, as if a yeti is afraid of falling, but is in a hurry somewhere) so it looks like it's running, but with small steps. It's cool, I would describe such a unit as a good fighter, but more for defense, with high health and speed, but low initiative and attack, possibly with infinite retaliation.

Now I'm watching the looped animation of a demon) he also jumps a little, you could say uncertainly, but he runs without pausing, that is, when all 4 paws land, he continues to move forward with his body and simultaneously starts a new step - he pulls his left arm forward and bends his right leg, and then pulls himself up with his arm and pushes off with his leg.

It's interesting, I should see how Skyrim trolls run, but I think their hind legs are too short to compare with the yeti.
