So: what could that 'iconic action FPS' be? Well, given Avalanche leads on the Rage franchise and Wolfenstein is currently in the hands of Machine Games, that leaves just Doom and Quake under id's potential management. But ZeniMax has emphasized that the new positions – which are based at id's Dallas studio in Texas – will be supporting 'the development of a long-running iconic action FPS', as well as reference 'sci-fi and fantasy environments'.
