Raven has a history of working with [[id Software]], the latest such project being ''[[Wikipedia:Quake 4|Quake 4]]'', which was released on October 17th, 2005 for PC, and November 22nd for [[Wikipedia:Xbox 360|Xbox 360]]. During his tenure at id, [[John Romero]] was the primary link between the two companies. Following [[ZeniMax Media]]'s acquisition of id Software, further partnerships are less likely to happen.
Since id's acquisition by ZeniMax Media, the [[Heretic]] and [[Hexen]] brands appear to remain with Activision and Raven, rather than id, although this appears to only apply to new products created within those brands (or new ports of the original products); id still has distribution rights over the original releases of 3 of the 4 games in those series (sans Heretic II, which id did not co-publish originally), and in fact publishes them on [[Steam]].
