: Do you remember GM's dialogue? He essentially said two things: I'm feeling
: sorry for myself (I've been punished/imprisoned for a crime I didn't
: commit) it's really quite peaceful if you just surrender and join me

: You could never accept his offer because death just puts you back to a
: checkpoint.

: But what if there was a skull hidden in a Flood level that, when active, when
: you die... an infection form Floodifies your body and you get to hunt and
: kill your allies.

: Their AI reacts in fear and horror to your Flood state and you get to hunt
: and kill them. It would be a bit like an opposing force mod but built into
: the game.

: Or if GM was allied with your allies at the time then you get to fight along
: side them but as a Flood.

: Perhaps you could detach your infection form from your body and run along
: walls and ceilings or under walkways like wot Stubb's hand could do. You
: could infect enemies to take over their bodies and fight as them or
: convert them to carrier forms and explode amongst a collection of enemies.
: You'd be able to jump very far.

: This is just for fun and you'd get various achievements for the different
: things you could do when playing as a Flood.

: If you die then you are reincarnated in an infection form and have to take
: over an enemy body or make your way back to reanimate your own body.

: If you kill a distinguished ally then their body becomes available to you
: too. (By distinguished I mean, a Spartan or the Arbiter, etc.)

: Maybe you could help the Flood win for once. A level could flip if you are
: playing as Flood. For example: The Halo 3 level where you fight to the
: control room would flip to where Elites and marines protect the pyramid
: from waves of Flood.

: You could still shoot your weapons so you wouldn't be limited to Stubbs'
: melee only gameplay but your melees would be really strong and your
: thrashing arm would be pretty long.

: What do you think? On the unlikely event that the Flood comes back, just for
: kicks, do you think it would be fun?

Would certainly be a hell of an easter egg. I'd say that's one of those things that's probably too complicated to make the cut, but after the kind of disappointing H4 eggs 343 really did put a lot of effort into making the H5 campaign have a lot of replay value, so I suppose it's possible.

Mostly I just want more "fun" skulls like CEA and H2A to make it into the 'normal' game. Give us infinite ammo, make us a tiny person fighting giant enemies, make the orchestral music chip tune tracks or the sound effects mouth noises.
