Guerrilla Games have recently announced that the multiplayer elements for both Killzone 2 and 3 will be closing on March 29th 2018. This announcement can be found on their official website, and on a recent tweet by the development group.
On March 29th, 2018, after more than 6 years of operation, the online servers for Killzone 2 and Killzone 3 will be decommissioned. The single player campaign for both games will remain accessible. More information: https://t.co/heASN9sJ4D

A statement on their official website explains,
“On March 29th, 2018, after more than six years of operation and countless battles between the ISA and the Helghast, the online servers for Killzone 2 and Killzone 3 will be decommissioned. The single player campaign for both games will remain accessible, but online play and related functionality will no longer work.”
The statement also included a thanks to the fans of the games,
“As we near the end of the online lifecycle for Killzone 2 and Killzone 3, we’d like to express how grateful we are for all the support and feedback we’ve received from the community over the last eight years. Your enthusiasm is what drove us to hone our craft and grow as a studio. We hope you enjoyed playing Killzone 2 and Killzone 3 online as much as we did creating them.”
It’s worth noting that both games have achievements tied to the multiplayer game modes. This means if want to complete the games to 100%, you’ll probably have to do so before the servers go down. Local multiplayer will presumably run like normal, where applicable.
Killzone 2 was released in 2009, with Killzone 3 following in 2011. The latest game in the series, Killzone Shadow Fall, will likely continue to support multiplayer for a while after its predecessors discontinue the service.
