Activision has now confirmed that 2018 will see the release Call of Duty Black Ops 4 and that Treyarch is the studio working on it. Last year's Call of Duty WW2 was largely well-received and there was an uptick in the sales figures, so the decision to keep going with the series has surprised no one. The single player campaign barely clocked eight hours and paled in comparison to the other games in the series. One thing Treyarch did do well though was the introduction of a four-player co-op campaign and we’d love to see this included in this year’s BLOPS. As with the last game, we’d like to see players have the option to take control of different classes to suit their playstyle. For example, snipers, heavy weapons specialists and all-rounders.
