Buy it on the 15th and find out :)
There is no local multiplayer,just online, sorry!
It hasn't been announced whether its offline or online, but it'll probably be online because they said that the award winning multiplayer from brotherhood will return, and that in itself was online, so chances are that it will be online multiplayer in revelations but there might still be the slightest chance in revelations for coop offline but no one knows yet.
No, the multiplayer function is online-supported only.
No, no and yes. The first two Assassins Creed's are not online. But the newest one, on Xbox 360 and PlayStation3, Assassins Creed Brotherhood, is online where you can assassinate online people while they try and assassinate you. So this answer depends on which Assassins Creed you are talking about.
if you mean multiplayer and online then yes and it is also quite fun.
No, but there are glitches, if you cheat or glitch it can get you banned forever
there is no cheat. multiplayer online games are not made to cheat. Silly Question.
Cheats generally are not enabled in online multiplayer games, for reasons that should be obvious.
A white one in Assassin Creed 2 and brotherhood and a black one in Revelations... They're like the one Jackie wears in Sleeping Dogs. You can buy it online.
They are the exact same games but I am going to say ps3 because in AC brotherhood when playing online you need to pay for LIVE on Xbox but on PS3 it is free.
Regular cheats won't work, but moded or glitched cheats may possibly
