20th Anniversary

20th Anniversary, also known as 20 Years of Halo, was a multiplayer event held for Halo Infinite. It was held between November 15 and November 22, 2021 during Season 01: Heroes of Reach, and commemorated the Halo franchise's 20th birthday. Unlike Fractures: Tenrai, or Cyber Showdown, the event would feature no progression, with players being granted a bundle of items upon logging into Infinite during the event's runtime.
