Back in June, we informed you that Bethesda Softworks filed for preliminary injunction against Interplay for the second time in their Bethesda vs. Interplay litigation, this time, among other things, claiming that Interplay was guilty of breaking Fallout canon, while at the same time claiming they had no right to use any of the canon at all.
