Here are three films you can watch if you get stuck
On the first one, its a fairly straight-forward game of "A Debt Repaid". I win with one casualty on Heroic.
The second is a bit more exciting - I win on Heroic but with only a handful of survivors. There's a lot of bloody melee fighting in this one.
The third is strange in that iu'Shee dies, but before the game can end in a loss, I kill the shade with my remaining archers, so it counts as a win. But thats beside the point as I do demonstrate how to effectively hold off Gor'Ash final assault, one of the most challenging (read: almost impossible) things in this collection of maps.
