Call of Duty: Black Ops 4 Xbox One X gameplay review of this latest entry in the popular first person shooter. The franchise continues to grow and this release from Treyarch focuses on a multiplayer only package. Battle it out in competitive multiplayer that focuses almost class based setups. Compete against others in Call of Duty's take on battle royale with Blackout. This is a mode that continues to evolve over the year. Then there's finally Zombies which is the largest yet with new and some old faces coming into the mix as the story wages on. This game has the polish you expect from the series, just without the single player campaign being a main point for this.
