The marketing wasn’t the issue, it just felt 343 were so bothered about getting Halo away from being known as a Bungie franchise that they tried to introduce so many changes to counter this.
It felt like they were trying to replace Chief as a character thus the big push on Agent Locke (he even got his own mini series). Chief was even in less missions in comparison.
Introduced squads which forced single player gamers to be paired up with 3 AI players over drop in / drop out co-op.
Cortana was butchered, ruining that relationship between Chief and Cortana we all liked. Would have been fine if the twist was the Didact was secretly controlling her or something but nothing. Did she come back in Infinite? Nope. Killed off screen in a sudden 180 to her villainous turn and replaced by a copy since they knew they screwed up.
Expected you to have read all the novels and the like to understand who Blue Team were and their relationship to Chief, had no build up to the characters and it felt like they expected you to like them without it being earned.
Everything they did felt like change for the sake of change, to mark it was a 343 game not a Bungie one and it’s hilarious as they tried to f*** around with the multiplayer in Halo 4 to make it their own before reverting things in Guardians.
