Guerrilla Games

Guerrilla Games is a Dutch first-party PlayStation studio and game-technology developer based in Amsterdam. Legally incorporated as Guerrilla B.V., the company began in January 2000 as Lost Boys Games, formed through the merger of Orange Games, Digital Infinity and Formula Game Development. It adopted the Guerrilla Games name following its 2003 acquisition by Media Republic, and Sony Computer Entertainment acquired the studio in December 2005.

The studio develops AAA interactive entertainment across the full production lifecycle, spanning pre-production, game design, narrative development, technical art, character and creature animation, 3D asset creation, audio, voice recording, sound design, and post-launch support. Its work is particularly associated with open-world action RPGs, first-person shooters, cinematic presentation, photorealistic environments, procedural world-building, motion capture, and online multiplayer technology.

Games and technology

Guerrilla is best known for the Killzone and Horizon series. Its catalogue includes Killzone, Killzone 2, Killzone 3, Killzone Shadow Fall, Horizon Zero Dawn, Horizon Forbidden West, Horizon Call of the Mountain, Horizon Zero Dawn Remastered, and LEGO Horizon Adventures. The studio has also produced earlier work under the Lost Boys Games name, including Dizzy's Candy Quest, Rhino Rumble, Black Belt Challenge, and Invader.

A central part of Guerrilla's technical work is the proprietary Decima Engine. Developed for the studio's own games, Decima supports advanced rendering, procedural terrain generation, artificial-intelligence systems, and large-scale world production. The engine powers Guerrilla projects and has also been used by partner studio Kojima Productions for Death Stranding and Death Stranding 2: On the Beach.

As part of PlayStation Studios, Guerrilla combines game development with ongoing engine research and studio-wide technology support. Its Amsterdam team continues to build experiences that join detailed world design, character-driven storytelling, high-fidelity visuals, and scalable interactive systems.
