Now under the new name of Rockstar Dundee.
Ruffian Games

Ruffian Games was founded back in 2008 by Gary Liddon and Billy Thomson. The studio worked with Microsoft on the Crackdown franchise and with 343 Industries on Halo: Reach for Halo: The Master Chief Collection. There are over 40 employees currently at Ruffian, which is now called Rockstar Dundee following the acquisition from Rockstar Games.

A number of employees were actually former Rockstar employees that previously worked on the Grand Theft Auto and Manhunt franchises. Both Liddon and Thomson will stay on as co-studio directors for Rockstar Dundee.

Details about the acquisition were not made public.

“We are incredibly excited to be joining the Rockstar team,” said Billy Thompson, Co-Founder of Ruffian. “Not only do we have the opportunity to work on some of the most successful entertainment properties in the world, but Rockstar’s investment in our studio is a great sign for the continued expansion of game development here in Scotland.”
There is also no current word on what projects they will be working on just yet for Rockstar Games.
