Brussee will head to Visceral Games' office at the Electronic Arts campus in California, where he will serve as an executive producer on an unannounced project. Job listings at the developer have pointed to the new game being an online action shooter.
Brussee served as a senior developer on Killzone, Killzone: Liberation, Killzone 2, and Killzone 3. Before cofounding Guerrilla Games, Brussee most notably worked at Epic Games in the 1990s as a coder on platforming game Jazz Jackrabbit.
In a farewell email to Guerrilla Games employees (translated via Google), Brussee said he enjoyed his time at the developer and that he hopes to find new challenges at Visceral.
