I really didn't mind the overall call-of-halo-field experience, i think multiplayer is well done, spartan ops not so good, but the campaign although visually rich, lacked the Halo feel that ruled in halo 1-3. For example, the Didact is the only main antagonist you get to fight, and you really don't even get to fight him, you just get a cutscene, in previous installments like halo 2, you have an epic encounter with a scarab, a heretic, a prophet and the brute chieftan, and if you were brave enough to go through it on legendary and with a few skulls in the mix, you would almost cry on how dificult each level was.
I really didn't enjoy all that activating this and activating that just to go through a level, although I did like all the detail put into the environment. For me, campaign just felt short against the other halo campaigns, I mean, there's so many enemies left out like the drones, and the brutes, even if I hated these furry ********, I truely liked hating them and bringing them down, and not to mention the flood, I MEAN COME ON, the flood are the spooky side of halo, and ever since Reach, the game was not the same for me because of the absense of the flood, the graveminds poems and such.
If future installments are to come I would really like to see more antagonists and get a chance to fight them, no more cutscene fights, and maybe make the promethean Knights a bit more scary if the flood isn´t making a comeback, and if the flood is coming back don't make them look like the flood from multiplayer even if they look great, they really don't look like flood, they look more like a resident evil character to me.
Well that's it, I hope I didn't offend anyone, and if I did it wasn't the intention.
