brought a second hand assassins creed but the keygen missing anyone help
The UPlay Passport comes with every new copy of Assassin's Creed Revelations, and can only be used once. If you want a new one, you'll have to purchase it through Xbox LIVE, the Playstation Store or Steam, depending on your console. The price is 10$ or 800 MS Points, however, receiving it this way will cause you to miss out on the Sentinel character.
Sorry for you, but if you want to play online you'll need this passport.
Your mistakes were twofold I'm afraid. You sprung your Tripwire without looking to see if the game you hunted, was the one you'd snare. And you sold me short... I'm no murderer. I'm an Assassin.
Oh, but you will have your reward for finding me. And don't think about running off without collecting. My blade is faster...or my name's not Emvidasch. http://youtu.be/k4kWbHePQbU?t=45s
