Master Chief, in search of Captain Keyes and his squad, is searching a mysterious installation under a swamp. He has come across a fallen marine and is viewing his camera record.

Mendoza: Why do we have to eat this old stuff, sarge? This cereal tastes like bits of newspaper, and this milk has been sitting on the radiator for about eighty years!

Sarge: Watch your mouth, son. That cereal is your history.

Mendoza: If the Covenant want to wipe out this particular part of my history, that's fine be me. If they've got a brioche on them, that wouldn't be bad, either. I'm starving.

The Chief fast forwards the tape.

Mendoza: It's weird.. something scrambled the insides.

Sarge: What's that, Cheerios?

Mendoza: Yeah, maybe. I dunno. Maybe it was a breakfast accident.

The Chief fast forwards the tape.

The captain and marines stand over an unopened box of cereal.

Keyes: Right, let's get this box open.

Jenkins: I'll try, sir. It looks like these Covenant tried pretty hard to tape it back shut. Maybe they were going to try and return it.

Keyes: Just do it, son.

Bisenti: I got a bad feeling about this...

Grunt: You have bad feeling about morning food nipple.

Sarge: What are you doing here?

Mendoza: Sarge! Listen!

A strange sound is barely audible.

Sarge: It's coming from inside the box!

The noise gets louder and the camera blacks out. The Chief looks around, finds an empty cereal box. He turns it upside-down. Nothing falls out. He discards it. From above, a humming starts.

343 Guilty Spoon: Oh! Hello! Greetings. I am the Monitor of Installation 04. I am 343 Guilty Spoon. Someone has released the Flood. I require your assistance.

Chief and Guilty Spoon vanish in a flash.
