Haha wtf, weird times. One of the most known cracker/pirate groups Razor1911 released Origin bypass for Battlefield 3 for legit customers, allowing them to play online without using Origin.
So from now on if you hate the EA’s Origin just don’t use it and play this game. Here are the release notes of this tool.
But since we don’t really want to spread pirated content there won’t be any links or more info here.
