Fallout Shelter

A Fallout spin-off for the iPhone is a hypothetical title that Fallout 3 developer Bethesda Softworks or its sister studio, id Software, could make in the future.

Project history
According to Bethesda's Todd Howard, several early designs have been pitched and rejected.

On November 5, 2009 John Carmack of id Software said that, while it's nothing official yet, he has an internal proof of concept made for a Fallout iPhone game. Both Carmack and Bethesda's Todd Howard are fans of the platform and any iPhone game based on Bethesda's IP will likely be made as a joint project between id and Bethesda. Carmack said that he will likely be personally involved in making the game, although currently he is too overloaded with work on other games. "At the very least I'm going to be providing code," he said. .

In April 2010, rumors have appeared about the game being titled Fallout Tactics: New Vegas, with gameplay similar to Fallout Tactics: Brotherhood of Steel for the PC and setting being based on Obsidian's Fallout: New Vegas. As of now, the rumor has not been verified yet.

Quotes
"I think that the world of Fallout is unique enough that it could work on any platform. I think some of the things we do like VATS, I think that could translate to any platform, particularly the iPhone," Todd Howard told us yesterday. "We've looked into those things, we just haven't found the thing that supports the brand well. I wouldn't be surprised if it does happen one day. The iPhone versions that we've designed and said 'Ehh, we don't think we're going to do that right now,' there are ... there are a lot of them."
