The thing that really threw me off was that Altair can't swim. He can assassinate people, he can sprint away from trouble and he can free run up buildings. But he can't SWIM! If anyone has any info on why please tell me.
kool first comment, just writing to ask about the second level. Under the water there is a cave , in the cave there is a table with a handle thing on it. then you put it in the circles on the walls, but i cant seem to find the other handle thing. Where is it???
