Although many Xbox fans were hoping to see Halo's Master Chief added to the roster of Super Smash Bros. Ultimate as the final fighter, it turned out to be Sora from the Kingdom Hearts series in the end.
Microsoft fans didn't walk away empty-handed, though - with id Software's Doom Slayer entering the battle as a Mii Fighter (Gunner) costume. Xbox's social media account has now also joined in on the celebrations, thanking the game's director, Masahiro Sakurai, for allowing its development teams to be part of one of the biggest video game collaborations of all time:
In the end, quite a lot of Xbox IP has been represented in the latest Smash Bros. game. This includes the playable fighters Banjo-Kazooie (Rare) and Steve, Alex, Enderman & Zombie from Minecraft (Mojang). And in addition to this, there's been Dragonborn (Bethesda), Vault Boy (Bethesda), and now Doom Slayer (id Software) Mii Fighter costumes. Steve and Alex will also be receiving amiibo in Spring next year.
And if you're still wondering about 343's thoughts about Master Chief in Smash, while it's clearly not happening at this stage now that the roster is complete, Halo's community manager, John Junyszek, admits it would be "sick" - as in cool.
If you would like to learn more about the latest addition to Super Smash Bros. Ultimate - the Kingdom Hearts games are available from the Microsoft Store on Xbox, and Kingdom Hearts III is available on Game Pass.
