During Xbox's new Halo ViDoc, which we've thrown up above for your viewing pleasure, there appears to be a slight tease for The Master Chief Collection ahead of its upcoming 10-year anniversary - despite the rest of the video focusing on the future of the series on Unreal Engine 5.

Yep, at around 50 seconds or so in the above clip, you can see the newly-named 'Halo Studios' team taking part in some sort of meeting - with an MCC background running in the distance. From what we can tell, the image reads as follows: "Halo: The Master Chief Collection - celebrating 10 years on 11/11/24".

Here's a still from the ViDoc showing it off:

Now, we're not entirely sure what this means specifically - heck, it could be nothing and just a little reminder of the game's upcoming anniversary. Still, we're inclined to believe it's potentially some sort of teaser, given its Easter Egg-like inclusion in a video that doesn't focus on Halo: MCC at all really.

We should find out about this teaser soon enough, but in the meantime, PC players of Halo's big collection do have something confirmed to look forward to. Halo 2's famous E3 2003 demo — which never made it into the final game back in '04 — is being added to the Steam version of Halo: MCC on November 9th.

Do you think Xbox will mark the Halo: MCC anniversary? Any ideas on what they could do? Throw 'em down below!
