Microsoft is seeking an experienced graphics developer to help create the "next generation of game visuals in the Halo universe" at Halo 4 developer 343 Industries.
According to a job on Microsoft's careers site, "DirectX graphics experience; Xbox 360 or DX11 experience is a plus". DX11 is, of course, not supported by the current Xbox.
The job ad reads: "Microsoft Studios 343 Industries is looking for an experienced graphics developer to help create the current and next generation of game visuals in the Halo universe. Work on one of the most exciting and creative properties in the industry; Work with the incredible 343 team to help drive the future of Halo."
While it was recently rumoured that Halo 2 Anniversary is in the works at 343 Industries alongside Halo 4, the developer itself denied that is the case.
