"Under the terms of the settlement, the license granted to Interplay to develop the
Fallout MMO is null and void, and all rights granted to Interplay to develop a
Fallout MMO revert back to Bethesda, effective immediately," announced the winning company. "Interplay has no ongoing right to use the Fallout brand or any Fallout intellectual property for any game development. ZeniMax will pay Interplay $2 million as consideration in the settlement, each party will bear its own costs of the litigation, and Bethesda will continue to own all Fallout intellectual property rights."
Interplay has permission to continue selling
Fallout Tactics,
Fallout and
Fallout 2 until December 31, 2013, after which time Bethesda gets sole control over all games.
