Did you know...?

1. Sergeant Johnson is a SPARTAN-I.

2. Gunnery Sergeant Edward Buck, an ODST, was once recommended to be a SPARTAN-I, and was the only one to turn down such an offer.

3. Jorge, of Noble Team, is the only SPARTAN-II on the team; Everyone else are SPARTAN-III's!

4. Noble Team's SPARTAN-III members were the first of their kind to make use of the Mark V variant of the SPARTAN-II's MJOLNIR Powered Assault Armor.

5. Noble 6, the completely customizable SPARTAN-III member of Noble Team, was an assasin and lone wolf type prior to joining Noble Team.

6. Cortana was based on the image, memories, and intelligence of the woman in charge of training the children of the SPARTAN-II program.

7. Noble 6 will be the first Halo protagonist to speak freely during gameplay.

8. The Rookie was the first Halo protagonist to not speak at all during the game.

9. The Rookie spent most of his time sleeping in Halo 3: ODST; He was sleeping in the prologue, until Romeo woke him up, then he was unconsious for 6 hours after his pod landed, and he's asleep again, under a staircase in the epilogue.

10. Many Red vs. Blue references were made throughout Halo 2 and Halo 3. The most notable is an Easter Egg in the latter, where, in the campaign level Crow's Nest, two Marines (voiced by some of the Red vs. Blue cast) are arguing over a lost password. The voices you get varies from one difficulty level to another.
