Assassin's Creed doesn't have guns. If anything, it's either a sneak attack with a knife to the neck, or it's bow and arrow, which Altiar can easilly evade. If you want to see what the game is about, go on gametrailers.com or check out YouTube on this game. There's some good videos up online, but when I finish this game, I'll be uploading my own videos.
Since you never claimed the hill, I take it.
