A:AnswerYes, all Xbox Series X discs are backwards compatible with Xbox One consoles. But PlayStation 5 discs are NOT backwards compatible with PlayStation 4 consoles. You just need to make sure you are using a console that has a disc drive. For example, the Xbox One S All-Digital Edition or the Xbox Series S do not have disc drives, so they cannot play any discs.

"Yes, you will be able to expect cross-platform play with Halo Infinite. Since the game is going to be available for Xbox Game Pass, you'll be able to play it with Xbox Game Pass for PC as well, which means both classes of players should be able to jump in-game together."
A:AnswerDefinitely will have multiple versions but probably nothing that’s honestly really worth it but for multiplayer gameplay online. Like in call of duty or other games similar. (Special characters) things like that
A:AnswerSplit screen campaign, and then if you are only playing offline then a “forge world” multiplayer gameplay between the two of you will be a option. If you get online then split screen multiplayer will be available for both of you to play against players live globally. That is most likely the only split screen content tho
A:AnswerIf you buy it on pc, and have an 8k monitor, and one heck of a graphics card....then in theory, yes u can certainly play 8k, just not positive how great of an experience you are gonna have considering the rtx 3090 would barely do it. And that's 1500 bucks, if u can find it.
