[Updated: We have since been informed that Bethesda's new Montreal office is mainly staffed by ex-Behaviour staff who worked on Fallout 4. Behaviour's team in Santiago, Chile remains the live development studio for Fallout Shelter.

Following the success of the mobile-only Fallout Shelter, Bethesda has announced it's opened a new mobile and console development studio in Montreal, Canada.

It will presumably handle ongoing support for Fallout Shelter.

Indeed, Bethesda says the studio - which is headed by industry veteran Yves Lachance - is already 40-people strong.

Company swap

What's significant about the immediate staffing levels and Lachance's involvement is that the original external work-for-hire dev team for Fallout Shelter came from Behaviour Interactive, which is also based in Montreal.

And until last month, Lachance was its SVP, Publishing.

So putting these facts together, it seems likely that Bethesda has acquired the original Fallout Shelter team, as well as additional staff from Behaviour, to ensure Bethesda Game Studios Montreal hits the ground running.

"We've worked with some very talented developers in Montreal for a long time, and decided it was time to open a studio there," said Todd Howard, Game Director and Executive Producer at Bethesda Game Studios.

"It's exciting to think about the new games we'll be building together."
