Back in June, Iron Galaxy Studios revealed that Killer Instinct would be coming to Steam later this year. And today, it has been confirmed that the game will support cross-network between the Steam and the Windows 10 versions. And given the fact that Killer Instinct already supports cross-play between Xbox One and Windows 10, all gamers will be able to play together.
This cross-network support will be available on Content Update 3.9. This update will add a switch that will enable the cross-network feature.
Killer Instinct will be released on Steam in the coming weeks, and during this time Iron Galaxy Studios will be testing this feature in order to make sure that all the kinks are worked out in a live environment.
“What that means for you is that you will see the option for cross play in your menus, but then there will be times where that menu item is turned off, and seemingly missing. Never fear, that is simply us working on things in the background, and your experience will not be affected as we do our work.
This feature being turned on/off will have 0 impact on your ability to play KI in-network, or between Xbox & Windows 10 players. So please, play to your heart’s content while we do the dirty work in the background.”
Here is hoping that more developers will start supporting cross-network play between Steam and Windows 10 (or GOG), as well as between the PC and all consoles!

Great news for the two people who own the Windows 10 Store version.
Great news for MS… because for multiplatform games you still need Xbox Live account even if you bought game from Steam Store. Steam players will need to link own Steam profiles to Microsoft account on Xbox Live. More gamers with Xbox Live account 🙂
BTW… Minecraft on Nintendo, Android, Apple iOS and PC also will need Xbox Live account after new update “better together”. You know… cross platform need single account to link people together and most users have MS account because them use Windows 8+.
I just hope Forza Horizon 3 gets the same treatment eventually.
Gears too.
Looks fun. I like the art style and the murder.
you can cross play between PC and another PC! what a time to be alive.
Most important is creation of single accounts on both platforms. In this case each gamer who buy this game on Steam must also login to own Xbox account (MS account) to play online.
Also Ubisoft use own accounts on games in Steam Store
It will be interesting if users of old Windows 7 can use for example Xbox Live Arena which require Xbox UWP app. Or if it will be accessible only for Windows 10 users.
Old Windows 7 will be supported. I think that MS want link existing steam accounts with own MS accounts (Xbox accounts). They need link all steam users to ms accounts. They bought Skype, LinkedIn, Minecraft because they want big single network with all Windows users linked to its family, friends, work.
Your fun comment appears to have triggered two salty Xbots.
holy F. what have i done?
About time. Now MS needs to continue the trend.
It will be hard because this is only MS DX11 game. All others use DX12 so it don’t make any sense to use Steam 🙂
Eventually MS will understand that nobody wants this exclusive store stuff. Just release your games on steam…
Don’t forget GOG(the best option), Humble Bundle and others. Any digital store exclusivity sucks.
I do like GoG. For such a “young” app it’s good and stable. But yeah, they should all go team steam 🙁
Now all they need are people to play the game!
So out of curiosity. If you own the game on Xbox One and purchase the Steam version. Can you play against one another remotely if you own both accounts with the assumption you have to login with Microsoft Xbox account to play online?
I imagine you wouldn’t be able to unless you sign into the Steam version with a unique Microsoft account. I wonder how this will be managed if I share the game on Steam using Family share.
Awesome news, I hope this becomes the norm and not stay as a special feature.
Good times.
And that is the proof that the issue is not the UWP system but the laziness of the developers/publishers in implementing the cross play between Steam and the Windows Store version
Iron Galaxy Studios doing the lords work. Fk Microsoft.
