Still seems odd to me that I paid for the Halo collection and then need to pay again for online multiplayer but for now, this is a very welcomed upgrade. I can see a world where a lot of people get an XBox to play the raft of incredible free to play games and Microsoft just made the prospect that much better.
One thing I'm wondering is that since Halo Infinite's multiplayer will be free to play, this means new Halo won't require Gold right? Seems like it, but you never know until it happens as Halo multiplayer has been behind the paywall. If new Halo multiplayer is incredible and also free to play I think this could open up a fun option for everyone to enjoy some shootery action for a fun price on PC and XBox.
