Crackdown 2developer Ruffian Games has revealed that it is working on a game withGrand Theft Autoseries developer Rockstar Games. New information about Rockstar’s next project has been stacking up, with one former Rockstar India employee confirming thatRockstar has multiple new games in development.

Job listings on the Ruffian Games site say that it is hiring for several positions to work on multiplayer action games. Some of the positions are for roles like senior engineer, UI engineer, and senior gameplay engineer. The seven job listings don’t talk aboutRockstar Gamesbut an article byThe Scottish Games Network, which was retweeted by Ruffian, said that “the studio is hiring people to work on games for Rockstar.”

Ruffian Games, which developedCrackdown 2and also worked onHalo: The Master Chief CollectionandCrackdown 3’s multiplayer, has several things in common with Rockstar. The two companies are Scottish and the Ruffian team is made up of several formerGrand Theft Autoseries developers. These commonalities likely help to make the companies great working partners.

It’s unclear what the two companies are working on, however. The Ruffian Games job listings are looking for developers with experience in making “multiplayer action games” for PC, PS4, Xbox One, and “future platforms.” Rockstar has made huge amounts of money fromGTA Onlineand nowRed Dead Onlinebut that doesn’t mean that the company is working on new versions of these. The developer may be working onBully 2and an online multiplayer mode, which is just what some fans have asked for in theirBully 2wishlists.

The job listings use of PC, PS4, Xbox One and next-generation consoles also may not mean much. There have been rumors thatGTA 6will be a PS5 launch title, that its map will be several times the size of theGTA 5map and that it will have a female protagonist. Rockstar did releaseGTA 5on PS3 and Xbox 360 before releasing it on PS4 and Xbox One but withGTA 6potentially offering so much content, the company may not feel like constraining the new game to older systems.

Whatever the two companies are working on, it seems like it’s a very large game. Rockstar Games has thousands of employees all over the world, so if it has had to call in Ruffian Games for more support and that company is hiring too, it means that the game is going to take a huge amount of resources.
