I don't see F2P Halo MP happening for one main reason. How would they make money on it? They already shot down the possibility of Halo Infinite having loot boxes after the lootboxes in Halo 5 were hated by the community. And direct microtransactions don't bring in nearly as much money as lootboxes do. Maybe they could make F2P work with a battlepass concept like Fortnite and CoD Modern Warfare are using, where you can either buy seasonal passes that include a selections of cosmetics and boosts, or work your way through the tiers of the battlepass for free by playing the game alot of hours. Honestly I'm not a big fan of battlepasses though, the implementation in CoD is nearly as obnoxious as lootboxes are, you have to play way too many hours to unlock everything for free, I put I think 60 hours into one of the seasons of CoD and only got like halfway through the battlepass tiers for the season, and I took advantage of two double battlepass XP weekends during that season. 

No PEGI rating so...

Edit: Also Xbox Exclusive? Should be Xbox Console Exclusive since MS puts their games also on Windows PC.

Depends on your outlook. If you need to make a Xbox account to play the game, it is technically a Xbox exclusive even if bought on PC. 

Only 13 votes? I guess people don't care that much about Mistwalker games. 

I'm pretty sure 343 has mentioned the only BR they have interest in is Battle rifle. 

Maybe. I wouldn't be against if they do it right. Though I'd rather the focus be on Warzone than a Battle Royale mode. For BR it needs updates often enough to remain interesting. Halo BR with all the vehicles would make it different enough from other BR games.
