Even though we covered some of Fable 2's achievements before, it wasn't until today that we can confirm what we previously told you. While we are still going to see achievements related to bigamy, gambling, and of course, orgies; it's the co-op specific achievements that have us excited. That's not to say we aren't excited about orgies.
As seen above there are a handful of co-op specific achievements related to expressions and combat, this was previously known. But what we didn't know before was that you could earn achievements just from joining a friends game and WATCHING them complete the requirement for it. It appears there should be one more achievement to add to the list, Voyeur.
The full list of achievements can be found over at 360 Sync.com.
