Ubisoft has released a full ten minutes of in-game Assassin’s Creed: Revelations footage, complete with developer commentary.
The majority of the video concerns Ezio chasing after a Byzantine captain who happens to be holding on to a key he requires. Unfortunately, Ezio is also wounded and unable to climb (at least until towards the end), so rather than a bunch of rooftop action we get a good look at the new bombmaking system.
After Ezio has blown up several guards, we get to see Altair saving his tutor from Templars (he might regret that, later).
Assassin’s Creed: Revelations is due on 15 November, for Xbox 360, PS3 and (until it gets inevitably delayed) PC.
