First i will give a very brief run though of what happened in the demo.

Victim: Slave trader

Location Jeruselum

I was a bit surprised when he just jumped down form the top of that building at the start since it was a high building but there just happened to be a cart full of hay or something there. After shoving a couple people that were carrying water above their heads a beggar started bothering altaír so he did what was necessary....grab him and throw him out of the way. After finding the entrance to where he needed to go blocked by 4 guards he had to find another route to the slave trader. He climbed up a building and pushed a guard off the top to create a distraction and then jumped to a beam and then past the guards. Next we find a bug, altaír killed a guard that was on an edge and we get to then see the guard floating in the air =).

Next altaír walks into a trap is surrounded by enemies, kills a couple, throws one into some sort of wooden structure, kills a couple more with well timed counter attacks and then chases after the slave trader. Each chase is different because of the unique AI in each character. Altaír takes to the rafters as to avoid the crowd and swiftly jumps on the slave trader after reaching the ground and then kills him(surprise surprise).

The game looks great and is definately one i shall buy (for the PS3) although the floating body was a distraction and an obvious bug that needs fixing it still looks great. The dynamic crowd is very interesting to see how they can either help as we seen with the monks on a previous demo or hinder you as people walk in front of you to slow you down, this is determined though various other side missions.
