HoMM VII Haven Units – Haven faction units from the seventh installment of Heroes of Might and Magic.

There's a suggestion on how to "fix" the movement animation for creatures.
Set any standard creature that can walk as the main model, then make that creature invisible. Attach the model of a pikeman or archer from Heroes 7 as an effect and make it walk. The main invisible model is responsible for the movement, and the effect will make the legs move.
