Remedy's newest game, Quantum Break, was officiallyas a same day launch as the Xbox One version, but don't expect to see it on Steam, as Microsoft's Larry Hryb has confirmed the Windows 10 game will be a Microsoft Store exclusive.
There are several reasons for this. Naturally, Microsoft wants people to purchase it directly from them without Valve taking a cut, but the game will also feature cross-save functionality. All saves on the Xbox One will be available to PC users, and vice versa. In addition, both versions of the game will share the same set of Achievements, so players who enjoyed getting two sets of Achievements for, say, Batman: Arkham Asylum won't be able to do it with Quantum Break.
“It is one game with shared saves,” head of Xbox games marketing Aaron Greenberg explained. “The way that works is if you unlock an achievement, it doesn’t matter where do it. It is one set of achievements.”
Microsoft also revealed the system requirements for Quantum Break, including "Ultra" specs. It will require both Windows 10 and DirectX 12.
Quantum Break will be released on the 5th April 2016.
