Today is a very big milestone for Microsoft, as the company's Xbox brand--and the Halo franchise--have turned 20. Halo Infinite's multiplayer even surprise-released to celebrate, and even PlayStation got in on the festivities via Twitter.

In response to an post from Xbox that included the original Xbox startup screen, PlayStation offered its congratulations. It came with a party popper emoji, though we are guessing the PlayStation social media manager did not actually have one on hand.

Xbox followed up with an offer to game together, which is possible via cross-play in many games on PlayStation and Xbox consoles. Halo Infinite isn't one of them, as it's only available on Xbox and PC, though those platforms can enjoy the game together.
