Treyarch is one of Call of Duty’s top developers. The makers of Zombies have also made Ranked Play in the past two CoD games, so you know its role as main dev on Black Ops 6 means Ranked Play will be a main attraction.
The developer looks to be at the top of its game again in Black Ops 6, the latest in the long-running sub-franchise of CoD that began way back in 2010. Zombies is back in a big way, but so, too, is Ranked Play in BO6 multiplayer.
