Fallout Tactics 2

Fallout Tactics 2 was a cancelled sequel to Fallout Tactics: Brotherhood of Steel. developed by Micro Forté. Pre-production started shortly before the release of the first game and it was cancelled around December 2001. After the game started selling rather poorly, the sequel was canned. Not much is known about this game, aside from the fact that unlike its predecessor it would feature Combat Armors. After it was cancelled, a petition to save it was even started by a fan of Tactics.

Rumors
Internet rumors during the time of Tactics 2's development suggested that the game may have taken place toward the east coast of the USA, perhaps even as far as Florida, and the major conflict was believed to be between man and nature. The Eastern Brotherhood of Steel was to be portrayed as even more fascist and oppressive, and as BOS only in name. Developer Non-Disclosure Agreements (NDAs) prevent retroactive confirmation or denial of this speculation.

Quotes

 * I'm also pretty disappointed that Tactics 2 never saw the light of day, since it's a title that would have benefitted from the experience and criticisms of the first game. Plus we were very conscious of heeding Fallout canon as best we could, and providing more interesting tactical missions rather than the run and gun focus of the first game. - Gareth Davies (NMA interview)
 * One of the biggest resources a drew upon when working in a more significant role on the ill fated FOT2 was varied treatises and comments from Fallout fans on what they felt constituted the Fallout universe. I was also lucky enough to have the original docs for Fallout on hand, and so between the original vision and a collective perception of that vision once realised it painted a pretty clear picture. Likewise, criticisms of the Tactics game world were taken on board and mentally collated. - Gareth Davies (NMA interview)
 * FOT2's major enemy would have made you it's bitch - Gareth Davies (RPG Codex forums)
 * IF we did Tactics 2 then I think we would want to make some major changes and we would have to think seriously about moving away from pre-rendered tiles and sprites.  - Tony Oakden (Freelancer interview)
