So I've just been combing every piece of the last four AC games to see if I've done everything in each one, and the only question left is how many leftover bonus blocks (the ones that go toward adding another health rectangle) I should have at the end of AC1. Personally, I've got 10, but according to this site, there may be 11. Could you look over your perfect AC1 game and let me know how many you have? I'd appreciate it. Also, let me know what system you're on.
In AC1 and Revelations, the sync bar could be a maximum of 20 blocks. In AC2 and Brotherhood the max is 25. Anyway, back on AC1, you get a new block every time you rank up (after assassinating a main target), or for every 15 completed "side objectives" (such as the View Points and Save Citizen missions).
