So, I'm playing and I just got Altair's armor. In order to get his armor you have to open all the tombs. That's exactly what i did, but it appears that after the first 3 tombs I opened, I haven't gotten any achievements for the next tombs. Now I have completed DNA sequence 9, but i still haven't received the gamer points for that one either. It says I unlocked them once completed them (gives me the notification beep) but when I push the middle button and look to see what I have done, it says, "you can view your achievements here." Also, when I'm playing and it saves, every time it shows the *!*. Any suggestions?
