Even though they won’t be in Halo 4 they could return in 5 and 6…
It depends on whether or not something new and different besides Prometheans could replace them.
If the Precursors show up, which I’m sure they will, maybe they will have something else besides the Flood to use against Chief.
Of course. Just please no more levels like Cortana. But I like the Flood most when they show up while in the middle of another engagement, all unexpected like.
I think they will. I think the ancient evil will have something in mind bahahahaha <— evil laugh
Yes its like gears without the Lambent.
If we’re not playing on the Requiem for the whole campaign, which has been hinted at a couple of times and kinda revealed in a screen shot of the Halo 4 home screen. Then I would love to visit a facility on a Halo (most likely installation 07), that has dormant flood forms in observation tubes. And they could have juggernauts, forerunner infected forms from each rate, infected animals and even infected ancient humans. That would be epic, maybe you could have some Spartan IVs that become fearful at the sight of the flood and then comment on how heroic chief must have been to go into the heart of a flood hive and come out alive.

Yes because it doesn’t feel like a proper halo game without them. 
I know there not in halo 4 but there’s still hope for halo 5/6.
