Technologizer reports on this unwelcome development for used game buyers: "SOCOM 4: US Navy Seals charts a new course in punishing used game buyers, and it’s at once better and worse than the status quo of $10 online passes. As described on the official Playstation Blog, SOCOM 4 will let all players access the game’s multiplayer portion — as it should, because online play has always been SOCOM’s main attraction — but used game buyers will miss out on special guns, game types, and other perks to be added later. To get these features with a used copy of the game, you’ll have to buy a $15 activation code. Sony’s spinning this bundle of features, dubbed 'SOCOM Pro,' as an enhancement for new game buyers, rather than a drawback for used copies. It’s semantics, sure, but it’s also the direction in which these used game restrictions should be going."
