Black Ops 6 Multiplayer is shaping up to be one of the most innovative installments in the Call of Duty franchise, introducing the Omnimovement system, a collection of small, chaotic maps, and brand-new game modes like Kill Order. Set in the 90s, Black Ops 6 also brings back a familiar roster of weapons, including the C9, which is essentially the MP5 from previous entries in the series.
