The Xbox 360 and PlayStation 3 versions of Mortal Kombat X are being developed by High Voltage Software, not NetherRealm, Warner Bros. has confirmed to VideoGamer.com.
The outsourced development, NetherRealm says, has allowed the studio to keep "100 per cent focused on developing for next-gen" and "maximise" the potential of Xbox One and PS4.
"NetherRealm is not developing the PS3/360 versions," Warner Bros. explained. "High Voltage is our partner focused on developing the PS3/360 and the team is giving those versions its full attention. All platforms for this game are built on NetherRealm’s tech with oversight from the NetherRealm."
High Voltage previously developed the PS4 and PC versions of NetherRealm's Injustice: Gods Among Us and Zone of the Enders HD Collection on Xbox 360 and PS3. It was most recently responsible for the PS4 and Xbox One ports of Saints Row 4.
Footage of the last-gen versions of Mortal Kombat X has yet to be revealed.
Mortal Kombat X launches on PS4, Xbox One, PS3, Xbox 360 and PC on April 14.
