Stuck in Arsuf
The worst glitch in Assassin's Creed.
Description: Exit the game at the end of Memory Block 6. When you restart, you will be alone and stuck in Arsuf with no way to advance.
Solution: There's no known solution other than to start a new game.
Prevention: After the Arsuf scene there are two "Saving Game" notifications just seconds apart. Do NOT exit the game in between them. The best time to exit the game is after Desmond wakes up from bed and gets on the Animus. This marks the beginning of the next Memory Block.
If you found this video because you're stuck in Arsuf, I highly recommend playing through again. Assassin's Creed is even better the second time. Try stealth assassinating all the targets, fighting with the Hidden Blade only, or playing without the use of the map and GPS. On Xbox 360, make sure you get the Conversationalist achievement. Don't despair about the glitch. You're not alone:

Okay, so I tested this out. Beat Arsuf normally and exited after the first save. Played through again unable to progress and exited. Plugged in the second controller and got to the end with both Altairs and... nothing. Desynched a few times to see if anything interesting would happen; still a mostly empty Arsuf.
Myth busted. I think Steve Adams is confused by what you mean by "stuck in Arsuf", as in, "the guards keep killing me before I reach the end".
Myth busted.
That's disappointing. Thank you for looking into this, Aurel.
So what you're saying (or what Steve Adams is saying) is, if you're stuck in Arsuf, restart the memory with the Altair clone glitch and you should be able to complete it? Worth trying if I get free time soon.
From the Fighting Glitches with Glitches department comes a comment from the linked YouTube video. Steven Adam suggests that if you find yourself stuck in Arsuf then you can become unstuck with the Double Altaïr Glitch.
I finish the mission with two assassins and I don't think it is possible to finish it with one, and you have to take care when fight because it is difficult when control two assassins at the same time and when aim the two assassins will attack each other
I mentioned the need for a second controller to be plugged in for the Double Altaïr Glitch to occur. He didn't know what I was talking about but continued:
When you reach the end of Arsuf the game runs normally but you still have two assassins, and you fight Robert with two assassins. When go back to Masyaf you return with one Altair
It would be nice if someone could confirm this.
