The 10th Anniversary Update brings with it two versions of KI:

The Killer Instinct Base Game will be FREE TO PLAY on all platforms: Xbox consoles (One, Series X|S), Windows PC, and Steam. The free KI base game will feature one free weekly rotating Fighter and Single-Player, Local, and Ranked modes.

The Killer Instinct Anniversary Edition will include all 29 Fighters, and all Premium Content ever released: the VIP Double XP Booster, holiday accessories, and more. This edition replaces the "Definitive Edition," which was delisted upon release of the Anniversary Edition.

The 10th Anniversary Update will go even further, with a few more changes:

- Improved matchmaking. We want to make it easier for folks to find matches quickly, regardless of which platform they’re playing on.
- Optimization for Series X|S consoles.
- Balance updates. That’s right – new meta for Killer Instinct, more than five years after the last adjustments!

The following Mature-rated content included in KI Definitive Edition will NOT be included in the Anniversary Edition:
- Definitive Edition App (featuring developer interviews, concept art, Killer Cuts soundtrack)
- Xbox KI Classic 1 & 2
- But DON’T WORRY! If you already own Killer Instinct Definitive Edition digitally, you will still be able to download the above content even after the Definitive Edition is retired.
