343i is reluctant to add Flood into their mainline Halo games. Maybe they want to keep the ESRB down, whatever it is, fine - Instead, what if they released a standalone game (potentially leading to a spinoff series) that focused in on Flood. Classic Halo shoot-em-up mixed with a bit of survival-horror.
The recent release of Floodfight for ODST has confirmed some longtime sentiments that the ‘spooky’ vibe of ODST would fit perfectly with Flood. So my shower thoughts are perhaps they could make ODST 2, and focus it in on the Flood? As an ODST, your more vulnerable than a Spartan so it would naturally lend itself to that survival-horror atmosphere.
What do you think?
