Call of Duty: Black Ops 4 is a multiplayer-only action game developed by Raven Software. It is the latest addition to the famous first-person shooter series, Call of Duty. The game is available on the PlayStation 4 platform and comes with a full version license. Black Ops 4 does not offer a single-player option, and players can only engage in multiplayer modes.

The game's core gameplay mechanics remain the same as previous Black Ops games, with players controlling their characters from a first-person perspective and battling each other in teams or individually with various firearms. However, Black Ops 4 introduces some new gameplay mechanics while also removing some elements from previous games. For instance, health regeneration is no longer available, and players must use health packs manually. Advanced movement and wall-running are also absent from the game.

Specialists return to the game, and players can choose from ten types of Specialists, each with unique skills. The game introduces four new types of Specialists: Ajax, Crash, Recon, and Torque. Players can customize their Specialists using the Pick 10 system of class creation. Black Ops 4 also features popular maps from previous games.
