Is the Chief portrayed in any way smart in the campaign? My memory is rusty and all I can think of is either "bring Cortana to location X" or "retrieve Cortana". Can intelligence even be portrayed in player controlled characters?
Pretty smart bastard to handle all that shit in campaigns and still keep on trucking.
Seriously though, all of the Chief's characterization is cursory and merely there to show that all he does, and wants to do, is win.
So, he really has no character.
And math frustrates him. Don't drop any pins in artificial gravity conditions around him. That's yo spine.
MC will have monologues much like Alan Wake.
Don't even joke like that, ha.
