Guerrilla is a growing development studio with an established reputation as one of Europe's leading game developers. Founded in 2000 as the result of a merger between three smaller studios, Guerrilla now employs over 160 developers from 25 different nationalities.

After the successful release of the original Killzone, Guerrilla was acquired by Sony Computer Entertainment in 2005. It went on to create the critically acclaimed handheld spin-off, Killzone: Liberation, as well as the award-winning sequel, Killzone 2. The studio released Killzone 3 to eager audiences in February of 2011, and is currently in the process of developing a second IP.
