"Advisory: Online multiplayer services for MAG, SOCOM Confrontation, and SOCOM 4 will be ending on 01/28/14," Sony said.
MAG and SOCOM: Confrontation require an Internet connection to play, meaning the first-person shooters won't work once the online services are removed. SOCOM 4, on the other hand, features an offline mode.
Sony was not immediately available to comment on whether or not it will continue to sell MAG and SOCOM: Confrontation even though they won't be playable.
MAG and SOCOM 4 developer Zipper Interactive was shut down last year.
