I got this game for Christmas on my PS3, although I had played the game on the 360 previously. I have to say, I do not regret getting this game, and I will never allow it to leave my home.
You play as Desmond, a man forced to get into a machine and relive an ancestor's past as an assassin from early 1100 A.D. Every once in awhile you will be pulled out of the machine because of random causes, such as the machine overheating, you need your rest, you need to be spoken to, etc. The best part of this game is the freedom you get anywhere, even during fights and missions. You can climb and hold onto literally anything, including cracks in the wall, bricks sticking out, or windows. My one complaint about this game is when you get Counter Attacks. At first, you are doing great and facing an ass load of men, and your scared like hell. Then when you get Counter, you can do 1 hit kills on almost everyone, you can basically run out into the open, kill a load of ordinary people(Not recommended, seeing as how you lose 3 bars whenever you kill 1 person), get almost 30 guys surrounding you, and easily take them out within 5 minutes.
