You already know Chris and Jill. They have new partners in Resident Evil: Revelations and this video introduces us to them. In raid mode a friend can take control of Parker Luciani or Jessica Sherawat locally or online.
Battle points return in Resident Evil: Revelations and in this game BP acts like experience points. When you level up you also get items as a bonus, which you can use to customize weapons.
Resident Evil: Revelations is slated for release on February 7th in the U.S. and January 27th in Europe.
