Ya, I haven't gotten that far yet. I'm in Acre right now. Attacking from the horse is easy, I hope they have some knights on horses or something to make it easier.
As for the fighting guard thing, am I the only one who finds enjoyment in running from the guards throughout the city? I enjoy making them chase after me going up ladders, leaping building to building, jumping off buildings, climbing them again, LOL, and it goes on. Also when they come up the ladder, it is too easy to kill them.
