Killzone 2 Pkg Upd 〈Ultra HD〉

First, I should confirm the platform. Killzone 2 was released for PlayStation 3, but updates might still be available via PKG files for PS4 if users are running older games. But usually, updates for PS3 games are on the PS Store, not via PKG for PS4. Wait, maybe the user is talking about a mod or a homebrew update? Or perhaps they're trying to install the game on a modded console using a PKG file and need the update version?
