Key Highlights:
- Call of Duty: Black Ops 2 multiplayer on PS4 and PS5 now runs entirely on dedicated servers instead of player-hosted connections.
- Activision says 100% of multiplayer matches have been migrated, removing host migrations and improving match stability and security.
- Black Ops also received a new PlayStation update, but dedicated servers have only been announced for Black Ops 2.
Nearly two months after returning to PlayStation, Call of Duty: Black Ops 2 has moved its PS4 and PS5 multiplayer completely onto dedicated servers.
Activision began gradually rolling out the new infrastructure several days before the September 10 update. The publisher now says 100% of Black Ops 2 multiplayer matches on PS4 and PS5 have been migrated to dedicated servers.
That replaces the peer-to-peer hosting used when the new PlayStation port launched in July.
Under the previous setup, one player in each lobby effectively acted as the multiplayer host. If that player disconnected, Black Ops 2 could interrupt the match while attempting a host migration, while differences between individual connections could also affect how stable a lobby felt.
Dedicated servers move that responsibility away from an individual player and onto Activision-controlled infrastructure. The result should be more consistent matchmaking sessions, no traditional host migrations and less dependence on the quality of one player’s home connection.
I think removing host migration alone makes this one of the most meaningful improvements Activision could have made to a multiplayer game originally designed around 2012 networking.
It also closes a question GLN raised when Black Ops and Black Ops 2 were first announced for PS4 and PS5. At the time, Activision had confirmed multiplayer would return but had not explained whether the ports would continue relying on older networking infrastructure.
Security is another reason the change matters.
The PlayStation port has already faced reports of players using exploits and malicious modifications, including incidents where accounts were allegedly manipulated or reset. GameSpot documented reports of Black Ops 2 players having ranks altered and, in more extreme cases, accounts becoming unusable after encountering suspected cheaters.
Dedicated servers give Activision greater control over multiplayer traffic and can make some forms of host-side manipulation more difficult. They should not, however, be treated as a complete anti-cheat solution. Server architecture alone does not prevent every exploit or modified client.
Activision’s wording is also specific to Multiplayer. The September update does not state that Zombies matchmaking has moved to the same dedicated-server structure, so the change should not currently be extended to that mode.
Interestingly, the networking change does not appear to have altered Black Ops 2’s underlying matchmaking philosophy.
CharlieIntel reports that the PlayStation version still uses the same general matchmaking system as the original 2012 game despite matches now running through dedicated servers. In other words, Activision has changed how matches are hosted without replacing the fundamental matchmaking model players associate with the original release.
The update also improves joining friends and fixes problems involving Custom Emblems, the multiplayer heatmap globe and parts of the user interface.
The original Black Ops received its own update at the same time, but its changes focus on lobby formation, friends and blocked lists, Custom Games, split-screen options and general stability.
Activision specifically says Black Ops now does a better job of forming regional lobbies to reduce network connection problems, but dedicated multiplayer servers have not been announced for that game.
That distinction has already become a talking point among players, with community discussion quickly shifting towards whether the original Black Ops could receive the same treatment. The current official state remains Black Ops 2 only.
The new infrastructure is particularly notable because these are relatively straightforward ports rather than full remasters.
Iron Galaxy developed the PS4 and PS5 versions, which launched in July after Activision brought both classic Black Ops games back to modern PlayStation hardware. GLN’s original coverage noted that Xbox Series X|S and Xbox One already had access through backward compatibility instead.
No equivalent dedicated-server upgrade has been announced for those Xbox versions. They continue to rely on the backward-compatible Xbox 360 releases rather than the newer PlayStation ports.
The PlayStation releases have nevertheless attracted a substantial audience.
Separate reporting based on sources familiar with Activision’s sales figures claimed Black Ops and Black Ops 2 had sold more than seven million copies combined after their July release, although Activision has not publicly confirmed that sales total. Earlier PS5 activity data also suggested Black Ops 2 was attracting considerably more players than the original Black Ops.
For Black Ops 2 players on PS4 and PS5, the September update therefore changes something far more fundamental than a menu or stability fix. Every standard multiplayer match now runs through dedicated infrastructure, finally removing one of the biggest technical compromises carried over from the game’s original era.
