Guerrilla Games will switch off the servers for multiple Killzone titles next month, rendering a deluge of modes inaccessible to players. 

The studio said the online features and multiplayer modes for PlayStation 4 title Killzone Shadow Fall, PlayStation Vita release Killzone: Mercenary, and PSVR title RIGS: Mechanized Combat League will all be shut down on August 12. For Shadow Fall, the move will render its Intercept co-operative mode unplayable.

The single player campaigns and modes for each game, however, will remain functional.

Prior to developing the Horizon series, Guerrilla's Killzone franchise told the story of an intergalactic war between the Interplanetary Strategic Alliance and the Helghan Empire. The series' lifecycle spanned the PlayStation 2, PlayStation Portable, PlayStation 3, PS Vita, and PS4. Shadow Fall, a PS4 launch title in 2013, served as the final installment of the series. 

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. 

Guerrilla provided post-launch support for each game, though RIGS received the least of the three. Following a winter update for the game in December, Sony shut down RIGS developer Guerrilla Cambridge and confirmed no further content would be released. At the time, Sony described the decision as a "regrettable" but necessary sacrifice that would allow it to meets its strategic goals.

Older games and online services are getting phased out

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 years-old games, including Far Cry 3, Assassin's Creed II, and Rayman Legends. 

In January, 343 Industries shut down the Xbox 360 servers for several Halo titles. The offline modes of those games are still playable, and many of the Xbox 360 Halo games have already been rebuilt and remastered as part of The Master Chief Collection -- which wasn't affected by the shut down.

Last week, Electronic Arts revealed that it will be phasing out the premium "BioWare Points" currency. Players could use the points to buy select downloadable content for Mass Effect 2 and 3, along with Dragon Age: Origins and Dragon Age II. The DLC for those titles can be purchased for free at the Origin Store. EA also reassured players that content previously bought using BioWare Points would remain available.
