Lionhearted’s Social Media Coordinator revealed on Twitter that Fable Legends will not be available on Steam. As Lauran claimed, this PC free-to-play title will not be coming to Valve’s distribution service. And if this is any indication, then we can safely assume that neither Killer Instinct will appear on Steam.

@pedrohasser22 It will be available on Windows 10 but not steam 🙂

Lauran later added.

@Vigg0 the article refers to win 10 supporting Steam, not Microsoft releasing all their games on Steam. Hope that makes sense 🙂

Whether this means that all the upcoming Microsoft games (Halo Wars 2, Gears of War Ultimate Edition and Sea of Thieves, alongside Killer Instinct) are Windows 10 Store exclusives remains to be seen.
