Financial papers from Interplay suggest that Bethesda may intend to sue the struggling publisher over its planned Fallout MMO.
Interplay retained the rights to make online games based on Fallout when it sold the rest of the rights to Bethesda in 2004. However, it seems there were certain conditions involved in this - conditions which Bethesda claims have not been met.
According to the Securities and Exchange Commission filing, Bethesda claims that Interplay is in breach of their agreement because it had not commenced "full scale development" of the Fallout MMO by April 4 2009, and has not secured enough funding for the game.
