You dont
I don't for-sure know about Assassins Creed 2 but Assassins Creed is 1 player and i think so is the second one.
You cant on AC2, but when Assassins Creed Brotherhood is released, you can then. :)
Unfortunately it is not. So far all the POP games have come out single player
No. Not possible on any of the games actually. Sorry!
assassins creed brotherhood has never been 2 player
no it does not have online play
Yes, if u don't beat assassins creed 2 then you will be totally lost when you play assassins creed brotherhood. because it starts off exactly where it ended and you'll be sooo confused of who everyone is how this all started what happened I HIGHLY recommended you play assassins creed 2 before you play assassins creed brotherhood. :)))
For Assassins Creed 1 No, for Assassins Creed 2 yes.
No, but I would suggest playing AC2 before playing AC Brotherhood if you care about the plotline.
as you play the game will show you what to press to do stuff
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 ;)
