A previous post mostly focused on the Fallout Extreme story. Here's more information about the gameplay in this canceled Fallout spin-off.
English version is in the right-hand column.
The best known canceled Fallout game is Van Buren (Black Isle's Fallout 3). But another Fallout game was also in development, mixing elements of Fallout Tactics with shooter gameplay.
It might seem fake at a first glance but I can assure you (with all my Fallout community reputation) that it's not.
It sounds like the guy who wrote it didn't even play 3, that's the whole reason the outcasts formed, because the brotherhood became all touchy feely with the natives... Yes, I liked the outcasts more, why? XP
