I've beaten the campaign in Hard Mode (The right mode IMO)
Very, very addictive. It's one of those games you don't want to end... and when you beat it, you just want more.
The addition of melee ingredients was a total hit. They really nailed it. Enemy A.I. is as good as always.
Visually is better than I was expecting. Special props to the cinematics... some of the best ever seen in a videogame. Textures are also neat.
I really, really wished the game's world was bigger with some hidden surprises... just like an OpenWorld RPG, with hidden enemies that are even harder than the final boss, or things like rare weapons. God of War managed to include those without making the game an actual Open World... that could be awesome for the next installment. Halo Infinite Open World approach brings a whole new world of ideas to the franchise.
I'm not a fan of shooters multiplayer so I will leave it as an awesome single player experience. I'm hearing everywhere that the game's multiplayer is like a drug though.
