A new title has been spotted on the Steam registry in the form of the 2011 fighting reboot Mortal Kombat. Reportedly the title comes with all of its Attachments intact compared to its XBox/PS3/Vita counterparts.
Steam registry is a pretty reliable source, however it is used at times as a placeholder for potential ports and doesn’t always come to fruition (Halo 3).
A port of Mortal Kombat would most defiantly be a welcomed edition to the PC as the system seems to always get stung in the fighter department.
