What he means by this is that instead of getting a fully fledged campaign and MP. They get a stripped down MP and it's stripped down so that they can monitise it as a f2p game. The campaign is actually stripped down too if you think about it. The same crap happened to TLOU2 but in the opposite way. They got a fully fledged campaign at least but MP was completely removed.Serious question, have you even booted Halo Infinite yet?
If so, how did you miss this?
Both the campaign and MP are accessed right from the main menu. So the people paying $60 for the game (or playing it on GP) have access to the MP right there in the menu just like every other Halo ever made.
