Killer Instinct

Killer Instinct is a one-on-one side-scrolling versus fighting game and the third main game in the series. Set several years after the events of the second game, it contains several characters from the previous game that each have their own story campaign. The series continues its trademark fighting system based on stringing together combos with a large amount of moves. They are not performed by individual button presses for every single hit, but by chaining together special attacks with button presses to continue the combo automatically, dubbed auto double. Characters can perform combo breakers to halt the hits, but these in turn can be countered with the new counter breakers, reversing the combo breaker and preventing the other player from performing another for several seconds.

The super meter built up while fighting is split up into two segments. The second segment enables shadow properties where moves do more damage and open up new combos. Typical of the series, an ultra combo can be performed to end the fight with a large rate of hits. A new addition is the instinct mode where a secondary meter offers the ability to enable a unique enhancement for the character, altering the combat. It also offers additional options to stop incoming combos with less penalties and dangers. While fighting a small meter appears below the combo value, showing how far it is coming along, how much more hits are possible and when it is likely to end, making it easier to anticipate.

The game was launched as free-to-play initially exclusive to Xbox One with Jago as the only character and all game modes available. The free-to-play version, dubbed Round One, has a single, rotating character and offers additional costumes and accessories packs as DLC. The eight characters of the first season along with costumes and accessories packs can also be bought in different bundles, also opening up early access to upcoming characters (such as Fulgore) and offering Killer Instinct Classic, the original 1994 arcade game along with the v1.5D variant and different changes and additions. The game offers offline and online multiplayer modes. This game entry only cover the free-to-play version and an overview of the available content, all bundles and DLC are listed separately.

The Combo Breaker Edition provides the eight additional fighters, but without the extras. Composer Mick Gordon returned for a new score for the second season.

The introduction of the second season and the new developers also introduces significant changes to the gameplay, altering the combo and manual system, altering the rules and introducing new elements such as air breakers and air counter breakers.

It also introduces cross-device multiplayer games between the two platforms. Some time after the release a Shadow Lords mode was introduced to the game. All purchases made for the Xbox One version previously carry over to the PC version. On a technical level the PC version runs at 60 FPS and has support for a 4K resolution. All stages received a visual overhaul and three new ones were added, making it 20 in total, including the new stage Arena of Judgement based on Halo 5: Guardians. A new lighting system was introduced as well.
