Microsoft’s recently begun an effort to bring Xbox One titles to the Windows 10 platform, aiming to create this sort of marketplace and hardware parity for their top-tier software. For instance, the upcoming Quantum Break, once an Xbox One exclusive, will also sell for the PC by way of the Windows 10 store.

What about bigger titles like, say, Halo 5: Guardians? It was always the assumption of fans that Microsoft would consider bringing 343 Industries most recent Halo to the PC, too, as a way to drive even stronger adoption.

Unfortunately, it doesn’t look like that’s happening. Microsoft’s head of Xbox, Phil Spencer, spoke at the company’s recent Build event this week about Halo 5‘s chances of coming to PC. Here’s how PC Gamer has it.

“In terms of Halo FPS on PC, I think there’s a ton of opportunity for us right now, but I don’t want to get into a world where we’re looking back, like at Halo 5. It doesn’t mean there’s nothing there that could ever end up on PC, but I’d much rather look forward with what our plans are.”

So, it’s safe to say Halo 5 isn’t likely going to release for the PC. An eventual Halo might, but what’s currently out there probably won’t.
