Halo: Campaign Evolved on PlayStation 5 requires players to link an Xbox account and gamertag to access the game’s content, according to multiple reports. The requirement applies to PS5 players, who must have an Xbox profile set up in order to play. In addition, outlets report that split-screen co-op on PS5 requires a PlayStation Plus subscription for participating players. Sources describe the local co-op setup as needing PS Plus access alongside the Xbox account linkage, framing it as an unusual combination of services for a PlayStation release. The reports cite official or community discussions around the title’s requirements and mention that both the Xbox account/gamertag and the PlayStation Plus requirement are tied specifically to the game’s split-screen co-op mode. Overall, the coverage focuses on the access and subscription prerequisites for PS5 players rather than on changes to gameplay, campaign content, or release dates.
