I've put in a handful of rounds in the Halo Infinite's Big Team Battle mode now, and all I can say is that it's chaotic fun.
The maps are just the right size that you don't need to run very far to get back into the battle, and there's just enough anonymity in the amount of players that you can't really blame any one person for a bad match.
I had a blast riding machine-gunner on a Warthog as my teammate tried to run down enemy players.
I'm looking forward to more maps in the future, and (hopefully) just plain getting better at this!
