Call of Duty: Black Ops 4's Blackout battle royale mode is getting a new map called, and set on, the infamous prison island known as Alcatraz. Activision says players will need to develop new strategies and tactics to succeed on the Rock, which will feature both long-range outdoor fights and tight, close-quarters combat inside. 

The original Blackout map was billed as the biggest map in Call of Duty history, but Alcatraz looks to be quite a big smaller, a point Activision seemingly emphasizes when it describes the new map in the reveal trailer as "close quarters battle royale." That approach makes sense if Activision and Treyarch are aiming for a different kind of battle royale experience, rather than just a different setting: A smaller map means more fighting, sooner, and shorter, more intense matches.
