While the Halo Championship Series hasn't officially announced the location of its next LAN, it appears that the HCS is returning to a familiar location for Halo fans.
Given that Halo has used the venue in the past, most recently with the Halo: Outpost Discovery in 2019 and the HaloWC Orlando Open in 2018 it's safe to assume that this will be the location of the next $250,000 Major Halo Infinite tournament.
Event: HCS Major Orlando 2022 (Split 2 Finals)
Dates: September 23rd - September 25th
