There are no active companies at this point lets try to revive it.
Mostly since this is a 5 year old game and population is so low
There are definitely not a ton, but I really wouldn’t say there are none. There are definitely still a few good options left. The front page of the Spartan Companies tab usually has companies that are attracting a lot of interest that is a good place to start.
Maybe you can create a company an start to recruit active players, but here wiill not work, only in the game
Although there are a lot of activity on Slayer and warzone and don’t forget halo 5 still have championship games too
My company was active for a week until it unlocked the Achilles armor and all the active players bailed (probably in search of a company about to get the helmet).
Achillies killed companies. If your company wasn’t created by X youtuber or “Something Something Achillies Number” it was pretty much certain to get few if any members and those you did have would leave for a company closer to getting the armour/helmet. Achillies was a good idea in theory but it completely ruined Spartan Companies and filled Warzone with farmers.
