Bethesda Softworks and Interplay have reached a settlement in their protracted dispute over the rights to the Fallout IP, specifically in regards to an MMO, which Interplay announced five years ago. Bethesda states that as part 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."

Bethesda parent company ZeniMax will pay Interplay $2 million "as consideration in the settlement," each side will pay its own legal fees, and Bethesda will retain rights to the Fallout intellectual property. Interplay has no ongoing right to the Fallout brand nor any Fallout intellectual property.

Finally, Interplay's rights to sell Fallout, Fallout 2 and Fallout Tactics will expire in December 2013, along with any other merchandising rights it had in association with those properties.
