In a nice little twist Triborg gets a fourth variation which is Cyber Sub-Zero.
During the ESL MKX finals Neatherrealm showed of some moves that Triborg. They showed of the new The Pit stage together with mainly Sektor and Cyrax how ever at the end of the stream the team showed a few moves of a never before mentioned fourth variation. It turned out Triborg is actually a Quadborg. Cyber Sub-Zero will also be playable by using Triborg. It’s a nice little surprise to see not only Cyber Sub-Zero but a fourth variation in the game.
You can see it for yourself at their stream right here:
