In an interview with Double Helix Games' Creative Director, Adam Isgreen, a lot of new information surrounding Season 3 was unveiled. The information given at the interview was then compiled by Reddit user galaxxus, who mentioned that a lot of the rumors about Season Three have been confirmed in the interview.
- Season Three will come out in March of 2016.
- Season Three will only work on Windows 10.
- Dojo will receive an updated tutorial.
- Tusk and Kim Wu from Killer Instinct 2 were confirmed to appear at launch and they will both have retro costumes.
- Season Three will add more characters than Season Two did (nine total) and they will be announced in the coming months.
- Killer Instinct will receive some major updates that change the game's balancing and the mechanics themselves. Older characters will be receiving tweaks to help balance them.
- Two characters will be reworked entirely and these characters will not be Glacius, Aganos, or Shadow Jago.
Killer Instinct Season Three will be available in March of 2016, exclusively to Windows 10 on Xbox One and PC. If you have the game on your Xbox One, you can also play it on your PC when Season Three launches, as the game has cross-play support and your purchase will carry over from Xbox One to PC.
