Does anyone have any information about when, or if, an application like Road to Legend will be coming out for Imperial Assault? Last I heard it should have come out this year as it was announced last year at GenCon, but so far nothing.

If all you need is campaign tracking, there are third-party apps for that.

You also mention Road to Legend, which makes the campaign a co-op. The FFG app is expected to be like that.

The last you heard in 2016, in their In Flight Report FFG said they're working on it and expect more information in 2017.

During the year FFG has confirmed it is still being worked on.

In GenCon 50 In Flight Report FFG said it's in testing.

So, from that you could deduce that potentially by the end of the year. I personally would like it to be great and bugfree rather than early.

See the other threads about it, includes the In Flight Report videos. For example:

Thank you! Yes, I did mean the co op features rather than tracking. I'll keep an eye out for it.
