So, I traded in L.A. Noire, and Assassin's Creed II for this, and currently I am on Sequence 2, memory 2, where you visit the doctor then save the citizen from the guards. Well...

As soon as I kill all of the guards and the screen goes white and then I go back to the DNA/Memory Sequence and I can't go onto memory 3 because it says I can't. I've replayed memory 2, six times so far, and each time it goes back to the DNA/Memory sequence. I am not falling below 1 health, so I am 100% sequencing, and the citizen isn't dieing. I don't get it.

It's starting to piss me off. So far this game sucks badly(fact I can't even get past the first stages of the game...) compared to the last...

hmmm i have no idea what your doing wrong, i have not had any problems with the game so far and im on memory sequence 6 i think.

Have you checked a guide for help?

So, I loaded up my game save again, thinking I would still be stuck. Turns out the game says I completed the mission? Must have been glitching.

glad you got it solved, i just finished the game and i really love the assassins creed series. Now its just to wait for Revelations
