I only watched a part of the video so far, but Halo was born in a time of arena shooters like Quake, Unreal Tournament and the likes. They turned it into a console-friendly experience but the basics were the same. The entire genre pretty much died in favour of military shooters, hero shooter, class-based stuff, and the art or roaming the map for certain weapons and power-ups to appear seems lost. Still, they're the last popular franchise that still manages to pull it off by trying to keep a balancing act between what old school fans want and modern elements (sprinting, class abilities, loadouts, ADS, etc.). Halo 4 probably leaned a bit too far into COD territory (I'm a Call Of Duty fan but if I want Call Of Duty I play Call Of Duty) and 5 had some odd MTX schemes, but the actual gameplay loop was pretty good, a great mixture of classic and modern. I think that if they can iterate on that they're good. Halo Infinite is gonna be the most ambitious Halo change in the franchise's history, so I'm curious to see what this means to multiplayer.
