On March 16, 2010, Kenn Lobb announced that they were not working on Killer Instinct 3 and that they might bring Killer Instinct back someday.
On September 17, 2012, Microsoft applied for renewal of the Killer Instinct trademark. In an October 2012 interview, Rare veteran Lee Musgrave, who was the former head of art at Rare, spoke on the issues of making Killer Instinct for XBLA: "We came close to firing off a conversion of Killer Instinct a few times, but there were licensing obstacles to that, and it never really had enough perceived interest to push it forward." On December 4, 2012, Microsoft's renewal for the Killer Instinct trademark was rejected by the United States Patent and Trademark Office due to the possibility of the game being confused with the unrelated TV series of the same name that lasted for one season in 2005. Microsoft had six months to respond to the ruling. The trademark dispute was settled when Microsoft and Fox reached an agreement in April 2013.
On June 10, 2013, at the Microsoft E3 2013 Press Conference, Killer Instinct was announced as being an exclusive Xbox One title, developed by Double Helix Games. The revealed trailer shown 3 returning character from the franchise: Jago, Sabrewulf and Glacius. An interview with the dev team also revealed 3 more characters: Cinder, Fulgore and Spinal. Developers also said that they would like to bring more female characters to the Killer Instinct franchise. In an interview, Killer Instinct will use a specific marketing strategy. After the initial release, a free demo would be available, featuring Jago as the only playable character (including his Story, Training and Online mode against other fighters). Players would be able to purchase the full game pack or fighters individually.
It was revealed in a teaser trailer at EVO 2013 that Chief Thunder would be making a return.
Shortly after the Gamescom 2013, a new female character, Sadira, was revealed.
- Three members of Sadira's clan can be seen in the upper left corner of Assassins Cave wearing a white version of sadira's old costume. They are on a balcony watching the battle.
- This currently appears to be the only instance in the game where there are spectator characters in the background of a stage (excluding the robotic orb in the background of The Crash Site).
- Broken tents and other materials are lying around on Devil's Landing.
- An alien orb is observing the battle in The Crash Site.
- Statues of tigers can be seen in Tiger Lair.
- In one of Chief Thunder 's retro costumes he is wearing a Killer Instinct Vest that shows logos of Rare and KI.
- In Glacius 's alternate color costume he has a slight resemblance to Spawn with green eyes and a black color.
- When the characters don't move during the fight, the music will slow down and play a remixed version from the original Killer Instinct Cuts.
- As seen in Fulgore's concept art, you will see a text in his left chestplate saying "Unit 3", meaning he is the third Fulgore in the series.
