Developer Iron Galaxy looks to be keen to add new characters into the popular fighter.
A recent survey, as reported by Inquisitr, is asking players to rank nine potential new characters, including a Halo Brute, Perfect Dark’s Joanna Dark and an agent from Crackdown.
The original Killer Instinct boss, Eyedol, was also included in the survey.
The likes of Gears of War‘s General RAAM, Halo‘s Arbiter and Battletoads’ Rash already feature in-game.
