Compare Killer Instinct prices across trusted key stores and find the best deal. Developed by Iron Galaxy Studios. Published by Xbox Game Studios. Released on 9/27/2017. Available on PC, Xbox. Genres: Action, Free To Play.

One of the most mechanically interesting fighters ever made sits on Steam right now for free - the catch is the online population reality check will hit you fast.

I came into this expecting a nostalgia cash-in and walked out genuinely impressed by how much fighting game is here. Killer Instinct's combo system is unlike anything else in the genre: you build combos in real time while the opponent actively tries to break them, and you can counter those breaks with counter-breakers, turning every extended string into a live read situation. Shadow moves delay your combo meter, Instinct Mode resets it entirely, and the whole thing rewards the kind of mid-match decision-making that separates players who lab from players who just mash. It is genuinely deep in a way that takes hours to surface. The Dojo mode deserves special mention. It teaches you how to play fighting games first, then how to play this one specifically - an approach that rivals anything the genre has produced. If you are brand new to fighters, or coming back after years away, this is the on-ramp you actually want. Shadow Lords, the rogue-like single player mode, stacks on top: you assemble a team, collect Guardians and Artifacts for buffs, and work through waves of increasingly hostile fights to stop Gargos. It is more engaging than the typical arcade ladder and gives you a reason to touch more than one character from the 29-fighter roster. Now the part that matters for online players. The netcode has a reputation that has aged unevenly. On Xbox ecosystem crossplay, it holds up well. Steam-to-Steam ranked can be rougher, with rollback inconsistency that community threads have flagged repeatedly. The ranked population on Steam specifically is thin, which means long waits or repeat matchups at higher skill brackets. If you are serious about climbing, the Microsoft Store version crosses play into the fuller Xbox Live pool and that changes the matchmaking math meaningfully. Worth knowing before you commit to a version. The free-to-play structure gives you a rotating weekly fighter plus full access to online modes, so you can get real time with the game before spending anything. The Anniversary update added matchmaking improvements and balance passes, and the roster now sits at 29 characters including guest slots from outside franchises. Stage destruction is present across all 20 arenas, though the stages themselves are largely cosmetic in terms of actual competitive impact. Controller support is solid and this is very much a gamepad or arcade stick title - keyboard players will get through Dojo fine but ranked on keys is not where you want to be. Killer Instinct on PC is a legitimate fighter being undersold by its own fragmented platform situation. The game itself is excellent. The Steam-specific online experience has real caveats. Go in with that understanding and you will find one of the more rewarding combo systems available at this price point. Fred, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
