Microsoft has shut down three ZeniMax studios that made games such as Prey, The Evil Within and Mighty Doom.
Arkane Austin will close, but some of its staff will join other studios to work on titles across Bethesda.
The studio was responsible for Redfall, a game that has now been axed.
The cancellation of Redfall means the $100 Bite Back edition of the game has been axed, too.
Players who spent the $100 will be able to claim partial refunds for the game's Hero DLC through a website set up by the company.
Tango Gameworks, creator of Hi-Fi Rush, and Alpha Dog Studios will also close.
Mighty Doom will shut down on 7 August, although Hi-Fi Rush will remain available.
Microsoft-owned ZeniMax said a small number of roles would be cut across select Bethesda publishing and corporate teams.
In total, around 9,400 game workers had been fired before the latest closures, a rate likely to outstrip last year's annual layoff records.
The latest staffing changes followed Microsoft's billion-dollar purchase of Zenimax Media, Bethesda's parent company, and its acquisition of Activision Blizzard.
