In the world of PlayStation 4, a file is the standard format used by Sony to distribute digital content. Whether you download a game from the PlayStation Store or install a patch, your console is processing a PKG file.

Call of Duty: Black Ops 4 is one of the most divisive entries in franchise history. It took a massive risk by removing the single-player campaign entirely to focus on three distinct pillars: Multiplayer, Zombies, and the new Battle Royale mode, Blackout. While it was innovative for its time, the game has aged in specific ways that potential players should be aware of.

Just so you know:

Note: BO4 has no single-player campaign. All modes (Multiplayer, Zombies, Blackout) are online-focused.
