The service is now featured at the top level of the marketplace, just right next to tabs for Games on Demand and Xbox LIVE Arcade.
Microsoft has also issued a statement regarding the matter which you can read below:
Microsoft is continually working to better organise our digital game content on the platform and your feedback played a part in that. Part of this new organisation means that Xbox Live Indie Games now has a tile on the top level of the marketplace right next to Xbox Live Arcade and Xbox Games on Demand
Inside of the new Xbox Live Indie Games section, you’ll notice that there are New Release, Top Download, A-Z, and Genre options, as well as a rotating carousel that shows off Kotaku’s Picks, Contest Finalists, and can be used to house other content as desired
This update is something we are extremely excited about as it really brings Xbox Live Indie Games to a higher level of visibility in the dashboard. We believe these changes will help even more gamers find and experience the great offerings you’ve all developed for Xbox Live Indie Games.
If you’re not from the US and have yet to see the update take place, don’t worry, as the update has gone live for US only for the moment. There’s still no word on whether when the rest of the world will implement this dashboard change.
