Yep, it's hard to win, but... It's a challenge! :) Hint: wipe out black rangers. Again. And again. The main goal is to eliminate rangers and step by step remove Witches and Elders. Also rearrange upgrades and use appropriate units and abilities. Place as much units as you can. And also there's some good combinations of skills that help to disable enemy casters and rangers.

You are playing historically accurate medieval archery sim. And you know, explosion proof vests were invented much, much later.
