Respawn Entertainment has "hand picked" an external studio to develop the Xbox 360 edition of its debut game Titanfall, according to its publisher.
Although the PC and Xbox One versions of Titanfall are in development at the Californian start-up, it remains unknown which studio is focusing on the Xbox 360 version. In a statement, the game's publisher Electronic Arts claimed that Respawn was "working closely" with the unnamed outfit.
The publisher told CVG:
"The 360 version of Titanfall is being developed by an independent studio hand picked by Respawn. The two studios are working closely to ensure the two versions are both delivered at the same level of polish and quality that fans expect."
Titanfall is the multiplayer-focused debut project from Respawn, the studio which was co-founded in 2010 by Jason West and Vince Zampella - former co-creators of the multi-billion dollar Call of Duty franchise.
Following a hands-on gameplay demonstration at Gamescom, CVG's Titanfall preview has suggested the game carries tremendous potential.
As part of a landmark partnership between EA and Microsoft, Titanfall will be a Microsoft exclusive title across Xbox platforms and Windows PC.
This is just one of several major exclusivity deals between Electronic Arts and Microsoft. Day-One Editions of the Xbox One will come with a free copy of FIFA 14, and the game will also come with an Xbox-exclusive Ultimate Team Legends mode.
Meanwhile, Xbox customers will also be given earlier access to various Battlefield 4 DLC.
Despite the extent of the partnership, EA Games executive Frank Gibeau recently told CVG that there is no perceived "strategic tilt" away from Sony.
"One of the things that struck me this week is how a tactical deal with one of our platform partners has been blown out and perceived as strategic tilt - that's a messaging error on our part. There is no strategic tilt," he said.
"The Sony platform and the Xbox platform are both very important to us. If you look at the previous generation we did tactical deals with both Sony and Microsoft throughout the cycle. Titanfall is different, it's an EA Partners game - everything else is platform agnostic."
He went on to pledge that no internally-developed EA games would be Xbox exclusive.
