Last month, Bethesda announced that not only would they be bringing the previous downloadable content for Fallout 3 to the PlayStation 3, but they would also be announcing two new expansions: Mothership Zeta and Point Lookout.
Gaming Union had the chance to catch up with Todd Howard, the executive producer on Fallout 3, to ask him about the two expansions. Specifically, about what players can expect in terms of their size:
It's [Mothership Zeta] going to be smaller, but Point Lookout is probably the biggest one in terms of space. Zeta will be close in size to Anchorage as it all takes place on this alien mothership.
So, it looks as though they will be of varied sizes. Mothership Zeta definitely sounds like it's going to be a complete departure from the stereotypical Fallout 3 universe though.
