The studio is bringing split-screen back after the June 25 update “introduced a stability issue only for splitscreen players”
Split-screen is coming back to Blackout on July 9, according to Kotaku. Treyarch has clarified what caused the issue in the first place: “Black Ops 4’s June 25th game update introduced a stability issue only for split-screen players in Quads, Duos, and Hot Pursuit modes in Blackout, and the feature was temporarily disabled while the team investigated a solution. A fix is currently planned for the next major game update on July 9th, which should restore split-screen for couch co-op players in all Blackout modes. This fix required some additional code changes, and as such, couldn’t be hotfixed sooner.” So, there you have it – you’ll be able to play couch co-op again soon.
Treyarch has temporarily disabled split-screen in Call of Duty: Black Ops 4 Blackout, the game’s battle royale mode, but so far it hasn’t been specified what particular issues the developers are investigating. In a Reddit post user FoxhoundFPS reports that they’ve “reached out to the team and was informed that we have temporarily disabled split-screen as we evaluate some known issues. We’ll share updates in the future after investigating further.” After being pressed for more information, all they had to say was that split-screen is “currently disabled and under investigation/evaluation.”
