BattleCry Studios has become Bethesda Game Studios Austin.
BattleCry Studios was formed in 2012 to create a free-to-play project called BattleCry, but it was shelved in 2015 after parent company Bethesda Softworks became concerned about the project.
Rather than close the studio, BattleCry has supported work for other teams and assisted the expansions for id Software's Doom.
Now the firm has become part of Bethesda Softwork's primary internal development unit, Bethesda Game Studios. The division already operates two studios - its HQ in Rockville, Maryland, and a Montreal office that it opened in 2015.
The new Austin studio will be managed by industry veteran Doug Mellencamp as studio director.
"We're excited to join Bethesda Game Studios and look forward to working together on some of the industry's most exciting new games," said Mellencamp. "Austin's incredible game development scene and talent will also allow us to push our games further than fans have imagined."
Game director and executive producer Todd Howard added: "As the vision, scale and ambitions for our games continue to grow, so does Bethesda Game Studios. We've had the pleasure to know the talented developers at BattleCry, and knew we could do great things together."
Bethesda Game Studios is best known for the Fallout and Elder Scrolls series.
Other internal Bethesda Softworks studios includes Zenimax Online Studios (Elder Scrolls Online), Arkane Studios (Dishonored, Prey), id Software (Doom, Quake), MachineGames (Wolfenstein) and Tango GameWorks (The Evil Within).
