My first two battles: one naval and one siege. Naval battles works well, boarding too, it's a 2 vs 2 battle, as the siege one. Siege battle is quite interesting, in my second video you can see how the katana heroes slaughtered all a ashiguru unit at the level of the dungeon. One bug: one of my unit that climb a wall stayed stuck into it!!!
to see the video: it's very simple: put them into your own replays folder (if you don't know where it is, do a research with windows "replays")
ADVANTAGE OF THIS METHOD (instead of a youtube video), you can zoom everywhere and see all details you want )
