Killzone developer Guerrilla Games' co-founder Arjan Brussee has left the Netherlands-based company to become an executive producer at Visceral Games, which is best known for the Dead Space series. Guerrilla was started in 2004 by Brussee and Arnout van der Kamp.

The sales for Killzone 3 have been disappointing in its first week, selling only 500K units, which is a third of what Killzone 2 did in its first week of release.
