Can I play Rainbow Six Siege online multiplayer without Xbox Game Pass and just Xbox Core?

Hi Zach. My name is Kyle and I'm an independent advisor.

Thank you for posting on the Xbox Communities Forum. Rainbow Six Siege requires Xbox Game Pass Core or Ultimate to play online. If you have Game Pass Core, you can play this game's online multiplayer.

Please reach back if you have further questions.

Thanks,
Kyle

Hi, Noah! Thank you for reaching out.
I'm AJ, an Independent Advisor for the Xbox Community.
I'm sorry you are experiencing issues playing Rainbow Six Siege.

With the exemption of free-to-play games like Fortnite, Warzone, Apex Legends, etc, all console games, purchased or not, require an active subscription to either Xbox Game Pass Core or Xbox Game Pass Ultimate (includes Game Pass Core) to play online on the Xbox Network. This also applies to physical copies of games.

If you don't have an active subscription to Xbox Game Pass Core or Xbox Game Pass Ultimate, this would be the reason why you are being prompted to choose a subscription plan when trying to play Rainbow Six Siege.

To clarify:

• Offline/story/campaign modes can be accessed without a subscription, it's just online features that require one.

• Game Pass Core is what Xbox Live Gold used to be, it's just that It was renamed and restructured to offer additional services in addition to online gaming. More information on the transition from Xbox Live Gold to Xbox Game Pass Core can be found at: https://support.xbox.com/help/subscriptions-billing/manage-subscriptions/xbox-game-pass-core-faq

Please let me know if you have any further questions, I'd be happy to help.
Best regards.

Rainbow Six Siege is not included with Game Pass Core.

Hey Ricardo, it’s just one game (rainbow six siege) that won’t let me play, all my other games I can play, online as well which means my gold still works and my buddy who bought the one game(rainbow six) he can still play it on his console. But since I bought the game pass it the Xbox thinks I don’t have rainbow six and I’ve been playing it for 2-3 years, now after game pass running out it won’t let me play

Rainbow Six Siege was free to play for gold members only for a period of time. In the end of the said period you have to purchase the game in order to keep playing

As stated in the xbox wire:
