After the last Press-Release there were many misunderstandings. To clarify it all, we asked ZuxxeZ for more details on the MP.
Here are the facts:
1. The Multiplayer consists of multiple servers distributed across the whole world. Joining a Server, you will launch in a city and talk with other gamers. Up to 8 players can group and solve quests together. This is valid for both PC and the Xbox 360 users.
2. Currently PC and Xbox 360 Owners cannot play together. It *can* be that in the future Windows Vista and Xbox 360 Users can join together in one game via Xbox Live.
3. You will not have to pay a monthly fee, not on PC and not on the Xbox 360.
