Gameplay. Call of Duty: Black Ops 4 is a multiplayer first-person shooter video game. Unlike previous titles in the Call of Duty series, Black Ops 4 is the first entry to not feature a traditional single-player campaign, and contains only Multiplayer, Zombies and a new battle royale mode called Blackout.
2024's Call of Duty game will reportedly be the next game in the Black Ops series, and will once again be set against historical real-world events. This time, the series appears primed to visit more recent history with the Gulf War of the early 1990s, as was previously rumored.
