EA is to announce the first details of Battlefield 4: Second Assault on November 1.
The details for the expansion pack are to come out of a Battlefield 4 tournament taking place in London. The competition will be livestreamed on Xbox LIVE at 6pm UK time.
Second Assault will follow the release of Battlefield 4's first expansion pack China Rising, and will be available first on Xbox One. Gamers on other systems will eventually gain access to Second Assault since it's only a timed exclusive. There is no word on how long they'll need to wait though.
Battlefield 4 releases on Xbox 360, PlayStation 3 and PC on November 1, with Xbox One and PlayStation 4 versions arriving on November 22.
