Call of Duty: Black Ops 4 rolls out its multiplayer open beta this weekend—today at 10am PST / 6pm BST if you preordred; the same time tomorrow if you didn't. Developers Treyarch and Beenox think it can be the "the best PC version of Call of Duty ever", and tell us it pulls from Destiny 2 and Overwatch in certain areas. 

Beenox is a subsidiary of Activision who developed a feature-limited, multiplayer-only version of Black Ops 3 for PS3 and Xbox 360 consoles. Creative director and co-studio head Thomas Wilson tells me its involvement in Black Ops 4—a multiplayer-only COD, without a singleplayer campaign—is no coincidence, but that the studio's focus is naturally on this weekend's multiplayer beta.
