As one of Europe's leading game development studios, Guerrilla has continually pushed the boundaries of technical and artistic excellence since its inception in 2003. Today, the studio employs 400 professionals from 25 different nationalities. Guerrilla’s state-of-the-art offices are located in the cultural and historical heart of Amsterdam, The Netherlands — a great place to work and play. Guerrilla was founded as the result of a merger between three smaller Dutch studios: Lost Boys Games, Orange Games and Digital Infinity. In 2005, it was acquired by Sony Interactive Entertainment after the release of Killzone on PlayStation 2. In the decade that followed, Guerrilla expanded Killzone into a successful franchise with a handheld spin-off and three sequels. Guerrilla's next title, released for PlayStation 4 in 2017 and for PC in 2020, is the critically and popularly acclaimed open world action-RPG Horizon Zero Dawn. The studio released its sequel Horizon Forbidden West in February 2022, with the Burning Shores expansion in 2023. This year, Guerrilla also released the PSVR2 title, Horizon Call of the Mountain.
