Visually stunning
I found the whole intro to the game rather strange but it was soon explained and I quickly became immersed in the detailed storyline. The storyline is quite strange as there really are two storylines with the Crusade-time story and present day story running parallel it can get a bit confusing at times (maybe it was just me!!!).
The gameplay in the game is really easy to grasp and withinn 5 to 10 minutes you'll be jumping across rooftops and performing stealth kills on unsusecting guards. The fight system in the game is something I really enjoyed about this game as you can engage several guards at once without being quickly overwhelmed (especially with the counter moves).
The only bad points of the game in my opinion are that it does become quite repetitve as you do seem to perform the same tasks on your way to the big kill and this can become annoying if it weren't for visuals and fight system. Also on the last level I kept getting 2 Altaïr's and couldn't finish the game! (Seriously irratating!!!!) I then found out that this happened if you had two Xbox controllers connected!
Overall I found this to be a brilliant game with stunning visuals and great gameplay, although the ending is strange and frustrating. Roll on Assassin's Creed 2!
