How do I publish my game in Unity onto the Microsoft Store?

I would start on
this page if you want to get a start on developing Xbox games with Unity. Check Unity’s website for the appropriate software downloads and forums for further help. A Microsoft
developer account is required too.

1. Build from Unity with the Windows Store build type

2. Make sure it works

3. Open a Windows Dev Center account (https://developer.microsoft.com/)

4. Publish game, setting the required price.

My game is already built to 100% just need to publish it is all.

Outside of the service provided by EA Access, there are no “alternative/publisher exclusive” storefronts on Xbox. Even EA Access only provides the ability to get a free license for games on the Xbox Store, which is then still served directly through
the Xbox Store - in partnership with Microsoft.

The Epic Games Store, Steam, Origin, Rockstar’s Launcher, and the Windows/Microsoft Store - these all exist as their own PC DRM delivery systems and storefronts, and will not affect how games on Xbox. When a publisher wants to put their game on Xbox,
either as an Xbox Game, or Xbox and PC as a Play Anywhere title, there will be an agreement signed between Microsoft and the Publisher that includes how much the storefront is paid per unit sold, which will likely be a standard rate for both physical and digital
sales.

The publisher meeting these requirements and terms is the only way that they can get their games licensed to be on Xbox, as Microsoft are the only ones that can “sign” games (a cryptographic verification system that ensures the Xbox will only run official
software). This of course is not the case with PCs, as they can run software written by anyone, anytime. Microsoft has zero incentive to allow a third party app/game store onto the Xbox platform, as they are responsible for, have their reputation effected
by, and profit from keeping control over the delivery and licensing system.

I'm Samy an independent advisor. Welcome to the Xbox community. How are you?

I found no mention of known issues for this game. I recommend contacting the game developer to check this out.

To locate the publisher, go to the game's description page in the Microsoft Store, scroll to the Additional Information section, and find the publisher in Published By.
