I Just completed the game XIII .. and what a great game it was.
You play as Jason Fly, who is a military man who lost his memory, he soon realizes there is allot of people trying to kill him, he has also undergone plastic surgery in order to uncover a plot by a group of 20 people who are keen in taking over the USA.
The whole game has a comic book feel to it, especially the cut scenes .. it was quite pleasant to play .. But the last task, which envolves killing an agent called Mongoose was one of the hardest missions ever, I had to replay it close to 20 times in order to be able to kill the bastard before he killed me 🙂
Highly recommend.
