I'm dual-weildin' mah SMG's!
After What Lobster Fish said, It depends where 343 go on. I have some Ideas.
1. Halo: Onyx
-Like Halo Reach, only following the events of the book, playing as one of the Spartan 3's.
2. A game following the UNSC and Covenant Seppies against the rest of the Loyalists after Halo 3. Player Character could be an Elite.
3. Some other Remake, perhaps of Reach, only this time following da chief.
