Alcatraz removed from the game entirely. Just like Shoothouse, the BR map has been removed from all the modes including private rooms. The map will still be available in CN version. Update from devs - “We wanted to let you know that Alcatraz will soon be leaving Call of Duty®: Mobile to make room for something awesome that is currently in the works. This is not permanent - Alcatraz will be returning later in the year. Stay tuned for more info on what exciting content we have coming this year.”
