Selv om det ikke er annonsert enda, tror fans at dette er Fallout Online, som har fått kallenavnet FOOL, en MMORPG satt i Fallout verdenen, ettersom at Interplay gav rettighetene til et slikt spill til Bethesda etter utgivelsen av Fallout.

Ifølge Feargus Urquhart, da Brian Fargo fremdeles var president i Interplay, la Fargo frem en mulig Fallout MMO som Black Isle skulle lage, men Urquhart nektet:
"The reason at the time, because I would have loved to have made a Fallout MMO, was that I believed that Interplay was just not in a situation where they had the resources to do it. When you go off to do an MMO it's going to cost $100 million before you get it on the shelf; you've gotta buy servers and you've gotta have service people, and you have to have Game Masters. It's an undertaking, and on top of that, it means that you do have to do all that stuff so what else are you going to focus on? What other games are you going to be able to make?"[
