Halo Re-ignition Pitch

Alrighty, so, here is my pitch: Covvies and UNSC trapped on sphere world, covvies know where the controls are, UNSC can actually operate them. They are forced, begrudgingly, to work together to prevent a flood outbreak/end of universe/plot device of your choosing.

Discuss, develop, critique.

On sphere world.

Covvie landed almost directly on controls luckily, so they have that area as a base.

UNSC is somewhere else in a jungle or something coz they're garbage at securing operational areas.

Both sides have seen a proverbial fuck ton of Forerunner things floating about, Sentinels and the like.

Both meet, fight, and then at some point a ton of Forerunner things start attacking both sides.

Unite against the old alien robots.

BALLS. YES.

Well I find fallens version cool
