Sony's UK arm will shut down online servers for a handful of first party PS3 games over the coming months.
And from May 20 2014, Gran Turismo 5 online features will no longer be accessible.
Users will still be able to play the above games in offline mode, excluding online-only titles MAG and SOCOM Confrontation.
No detailed explanations were provided for the server closures, although such measures are typical for older titles with small - and usually dwindling - active player counts.
The first Resistance game was a PS3 launch title in 2006, with sequels following in 2008 and 2011. SOCOM Confrontation was released in Europe in March 2009, MAG has been active since its January 2010 launch, SOCOM Special Forces arrived in April 2011, while Gran Turismo 5 hit stores in November 2010.
