Halo: Campaign Evolved, the remake of Halo: Combat Evolved, has sold noticeably poorly on PlayStation 5 despite marking the franchise's first-ever release on a rival console after decades of Xbox exclusivity. By contrast, Call of Duty: Black Ops and Black Ops 2, ported to PlayStation with no updates or changes from their original versions, have vastly outperformed expectations, highlighting how strongly multiplayer-driven titles continue to draw sales compared with single-player-focused releases.

According to analytics firm Alinea Analytics, Campaign Evolved sold around 351,000 copies on PlayStation in July, trailing titles such as Palworld, Minecraft and Grand Theft Auto 5, alongside roughly 212,000 on Steam and 900,000 on Xbox; for comparison, Halo 3 alone sold 14.5 million copies on one console. The Black Ops ports, handled by Iron Galaxy, have sold a combined 11 million copies for an estimated $435 million (3 million for Black Ops and 8.2 million for Black Ops 2), having previously only been available on PS3. Campaign Evolved has received positive reviews for its new missions and updates, but its lack of PvP multiplayer is thought to have limited its appeal, reflecting Halo's diminished cultural pull since Bungie's split from Microsoft after Halo: Reach.
