the flood makes the game more challenging to me. at least in H3 it did. having the tanks and all the new forms in it.

Just to confirm some info, this is before halo 1. its when there were still many spartans fighting/alive. As we found out in the campaigns, elites/brutes were discovered in later halo's so it wouldnt make sense for them to be in this one, otherwise thatd throw off all the other storiess, as for who your going to fight, wave upon wave of jackals/grunts, the book halo: fall of reach explains this rather well. u pretty much fight thousands and thousand of each of them, im curious to see how the campaign goes because Reach was destroyes along with most everyone on it

Brutes would be great! Strong melee, but slower to compensate

it would actually be posible bc in H1, u don't know who the prophets were, but yet they were behind the whole damn thing. so it's not to say that it could be similar on Reach. so it is POSIBLE to have something like brutes. on the other hand now i do have to agree that i don't know y they would put brutes in bc they weren't even part of the halo story til later. that's y i think they just need to put something NEW to fight. the flood and brutes came later in the story.

Brutes - No because the only spartan that ever fought Brutes was MC 117

Flood - No because they never settled on the planet Reach

Arbiter - Yes. I think an Arbiter should be present during a cut scene or a level, but not entirely

MC 117. . is master chief... lol.
I need to watch Halo Legends again to get my facts straight because Im a huge halo nerd.
I cant just play the games, i have to learn the story, and the psychology as well as the philosophy of halo

Contrary to popular belief just because the flood weren't "reported" yet does not mean they don't exist. It would be a good part if they came across some of the flood in a level but they report it as an unseen force of the covenant.
