I was looking for evidence of Fazely being shut down, because it seems weird that such a thing could occur without an article being written. Citing one game's credits for evidence of a second studio not existing isn't good evidence.
I've not searched LinkedIn for resumes for Fazely Devs. If anyone has an article, I'd be really interested in reading it.
Apologies if this comes off as hostile, that's not the intent at all.
Yes, when I first saw updates on LinkedIn about Fazeley employees, I was a bit surprised. In the end, together with any new recruitment updates for that studio, the lack of mentioning by Rare and Microsoft, and the lack of mentioning on Fazeley's website, one can only come to the conclusion that it got silently closed down. That no articles appear on game dev closures happens more often than you think though. LinkedIn is pretty helpful in that regard.
The credits aren't evidence for the lack of Fazeley, just evidence for the general studio size.
