Halo: Campaign Evolved’s PS5 version requires specific PlayStation Network access for local split-screen co-op, according to multiple reports citing a developer Q&A. While the mode is described as an offline feature, both players using the PS5 split-screen campaign need active PlayStation Plus subscriptions. The requirement applies to how the game handles two accounts during split-screen play on PS5, with sources stating that both participating accounts must have PlayStation Plus. Reports also note that a Microsoft account is involved in the setup or access requirements, adding another condition beyond PlayStation Plus.

The issue has drawn criticism from players and coverage outlets, which describe the requirement as unusual given the couch co-op context. Overall, the different articles agree on the core point: the PS5 split-screen co-op experience in Halo: Campaign Evolved requires two separate PlayStation Plus subscriptions—one for each player’s account—rather than being available with a single subscription or without online subscription checks.
