Aiming down ur sights!!! that wouls help a lot in combat. along with a cover system.
another cool features would be different body types like skinny fat or just ripped like a super mutant. lol.
idk who would be fat in the wasteland but iti would cool to have all those options during player custimization. that would make diffenet body types in other characters too.
