omg you took the words out of my mouth! i always thought the same thing, odst and reach were only covies, and no flood, and now no flood in halo 4, its like wtf? flood is essential but i guess it wouldn't make sense storywise. so what they should do maybe after halo 6 or something is make a game base only on the flood. :OOOo perhaaaaps you could play as a forerunner or somethign :DDD that would be cool and it would seriously should the true devestation and disturbance of the flood. l ike how it is in halo wars, just first person, that would be the scariest flood lol. it could tell about how things where when the flood first was discovered, etc. and the hud could look mainly like what we're used to, just with forerunner weapons implemended all the time, like promethean weapons, and other forerunner weps that would be badass but very scary lol. it would be like a mix of halo 3's flood plus halo war's flood.
