Once you've downloaded it, all you need to do is start the game at the start menu as you normally would. When you load the game, it will jump to a short cutscene of Rebecca talking about how she had fixed some of Ezio's memories. Once the Animus loads, there should be two new mission symbols on your mini-map. Go to them to initiate their content.
Note: You shouldn't play the Da Vinci Disappearance until you completely finish the Brotherhood campaign, as it contains spoilers.
AT the verry start of the game
assassins creed and army of two
Because you may be blind
You press start and leave the animus..
in assassins creed 3 there is no multiplayer campaign but you can go against others in the multiplayer
You go out and buy a legal copy.
no it doesnt
you could start a new file
There are four cahracters for you to unlock but you start with ten default characters.
ezio will start to buil the brother hood by rescueing some of the towns folk from the guards about half way through the game (eliminating the borgia towers gives you more assassins to use in battle, but i think the cut off is 8 at a time)
You can replay levels on Assassin's Creed 2 by pressing start and going under DNA sequence.
Yes and no. Yes it is technically Assassin's Creed 3 since it is the third game to be released on a home console, but it is not the conclusion of the main trilogy. They are saving the titles with the numbers for every time they start a new era with a new assassin.
