Earlier this week, Microsoft rolled out cross-play multiplayer support for Gears of War 4, allowing Xbox One users to play against people on PC. Now, Xbox boss Phil Spencer has spoken out to say he hopes more games support cross-play in the future, though Halo Wars 2 won't be among them.

"I hope so," Spencer said to a fan (via DualShockers) who asked if more games will support cross-play. "That's our goal."

He added that Halo Wars 2 does not support cross-play "for some longer-standing engine reasons." But as Microsoft looks to the future, "cross-play is a good feature," Spencer said.

Last year at E3, Microsoft confirmed Halo Wars 2 would not have cross-play support at launch but teased that the feature could come as a post-launch update.

In other Halo Wars 2 news, an open beta for the RTS sequel is going on right now on Xbox One and PC.

Also on Twitter, Spencer was asked about Microsoft's Project Scorpio console. Specifically, someone wanted to know when the mega-powerful system would be available to preorder. It remains to be seen when that will be, but Spencer says you may want to wait until you see games running for it.

Recently, Spencer said he played games for the first time on Scorpio and said they "played great."

Finally, Spencer reiterated on Twitter that the Xbox One Elite controller will work on Scorpio. This is no surprise, given basically all Xbox One peripherals (and games) will work with Scorpio.

Scorpio goes on sale this holiday, though its release date and price have not been announced yet.

In other news, a developer said this week that Scorpio is a "full blown next-gen machine," compared to the "half-assed" PS4 Pro.
