Killzone titles and RIGS

RIGS released in 2016 and has no connection to the Killzone franchise. The virtual reality title lets players take control of mechanized rigs and duke it out across a range of multiplayer scenarios, including team deathmatch and a version of American football.

At the time, Sony described the decision as a "regrettable" but necessary sacrifice that would allow it to meets its strategic goals.

Guerrilla Games is the latest developer to shut down online servers for its older titles. Earlier in the month, Ubisoft announced its own plans to axe online features for several of its now
