Give it to another developer. Complete franchise reboot.No, thanks. After the third game, I'd rather they left the franchise die now. I won't be able to stand another abomination like that.
Get rid of Paxton, Alma, Point Man. Keep clone troopers, dive kicks, slide kicks, leaning, awesome weapons, slow-mo, incredible AI, amazing level design (except for the repetitive offices, as everyone knows), and perfect atmosphere.
