@swordsaberx what do you want their backstories to be about? And if you want Spartan X in the story how should I introduce him? Also, I was thinking about the characters and their roles:

Deadbeat – close quarters combat specialist
Recon – long range and stealth, obviously
Rook – mid range (assault rifles and smgs)
Sanchez – can use most weapons provided by the UNSC, but prefers to use his custom good plated magnum.

What do you think of this idea? Let me know if you want anything changed.
