Just a GMV I made using footage from the first four trailers released, and In the House/In a Hearbeat by John Murphy, from the 28 Days Later soundtrack. Enjoy; I tried to show Altair assassinating three different targets. Let's see if that worked.
Oh, and apologies for the 'Created with Flip4Mac' thing. I actually created this with iMovie, but had to use Flip4Mac to convert the .wmv videos.
