As far as I know you cannot. But you do get to play as Altair once in the game. You do get "The Armor of Altair" at the end but that isn't anything like the one in the first. It is just Ezio's outfit he had throughout the game reskinned and a little bit remodeled.
Edit: I have recently discovered that if you connect with uplay (E on the PC or triangle on the PS3) at the menu screen of Assassin's Creed II then once you go in there, go to the WIN section and you can download Altair's Outfit (which is exactly like the Assassin's Creed I Altair armor from the first). You must have a Uplay account and some uplay points for this to work.
I'm not sure if it works with Xbox though.
no
For Assassins Creed 1 No, for Assassins Creed 2 yes.
the final armor is altiars armor it is the lightes,most durible, and looks really cool.
Assassins Creed Bloodlines is 5 weeks after Assassins Creed 1. This is what happened to Altair before he dies. Assassins Creed 2 is a completely different thing. The main story is the same but the story of the main characters, Altair and Ezio, are very different. Assassins Creed Bloodlines does not have the Animus in it as much as Assassins Creed 1 & 2
There is a certain mission where you put on the guards armor and walk to meet the spaniard
1. Asassins creed 2. Asassins creed 2. 3. Asassins creed brotherhood 4.Assassins Creed Revelations 5. Assassins creed 3 6. Assassins Creed III Liberation
you can only change the color and the armor type, then you get Altair's armor, so no.
yes but buy assassins creed 1 first to get familiar with it.
There are currently 4 Assassins Creed games out for PS3. There is Assassins Creed 1, Assassins Creed 2, Assassins Creed Brotherhood, and Assassins Creed Revelations. The 5th installment, Assassins Creed 3, will release this October 30th.
I don't for-sure know about Assassins Creed 2 but Assassins Creed is 1 player and i think so is the second one.
assassins creed 2 has definatly a larger map but the kill streaks are much better on assassins creed brotherhood but the story line is alot better in assassins creed 2 hope you have fun with assassins creed 2 or brotherhood ;)
