Battlefield 4 when the console launches on November 22. EA previously announced that the map pack, which features four "fan-favorite" maps from Battlefield 3, would launch on Xbox One first, and that remains the case. There are no details on the DLC's price (it'll be free for Premium members) or when it will launch on other platforms.
The news comes via an EA press release (the date confirmed by VideoGamer) for an event showcasing the map pack. The event is to be streamed live from London on November 1 (12PM ET/9AM PT, 5PM UK time), featuring two teams of 32 players each fighting it out on Xbox One. A European team will be led by Xbox EMEA rep Graeme Boyd, while the US team will be led by the appropriately named (for once) Major Nelson, AKA Microsoft's Larry Hyrb.
