Halo: Campaign Evolved, a remake of Bungie's 2001 classic Halo: Combat Evolved, launched on 28 July as the first Halo title released simultaneously on PlayStation, PC and Xbox. The PlayStation release marks a symbolic moment for the long-running Xbox-versus-PlayStation rivalry, but it has been overshadowed by player claims that weapon performance differs between platforms, alongside the game's unprecedented lack of a competitive multiplayer mode.

Players, led by a Reddit user who posted comparison footage, allege that the assault rifle is noticeably less accurate on PS5 than on PC or Xbox, despite firing marginally faster, with bullet spread and recoil patterns appearing to diverge across versions. The base weapon is the 32-round MA5C rather than the original 60-round MA5B, though the classic gun can be restored via a modifier. Developer Halo Studios, making its first Unreal Engine 5 title, has not commented on the accuracy claims or on why competitive multiplayer was omitted, leaving fans to speculate whether the two issues are connected.
