never officially transitioned to the PS4 is the architecture of the PlayStation 3

The phrase is a product of modding scene jargon and misinformation. There is no native PS4 version, no exclusive downloadable package, and no official PKG from Activision. Legitimate access is limited to cloud streaming (PS Plus Premium) on PS4/PS5. For offline, native play, users should turn to PC, Xbox backward compatibility, or original PS3 hardware.

While a native 60 FPS remaster does not exist, the jailbreak scene has created something interesting:

The desire for a PS4 PKG of Black Ops 2 is ultimately a story of nostalgia colliding with corporate strategy. Activision chose to remaster the Modern Warfare campaign but left the Black Ops series largely to legacy platforms. The myth of a "PS4 PKG exclusive" serves as a digital Grail for fans—a hope that somewhere, hidden in the depths of the internet, lies a way to play one of the greatest shooters ever made on the generation of hardware that followed it. Until an official native port is released—a possibility that grows slimmer as we move further into the PlayStation 5 lifecycle—the Black Ops 2 PS4 PKG remains a phantom, a symbol of the era when physical media and hardware architecture created insurmountable walls between the past and the present.
