There's a very frustrating inconsistency with Nornfang in the campaign.
It is on the ground and usable in Blue Team's ship when Osiris finds it, so Linda left it behind, right?
During the cutscenes in the first Genesis level, this seems to be the case, as her sniper is a regular UNSC sniper rifle.
But in-game, she will always be equipped with Nornfang. I can almost look past this, I guess 343 didn't think to code her with a different weapon, whatever, but it doesn't end there!
In later cutscenes, such as when Osiris meets Blue Team on Genesis and when Cortana reveals herself, her sniper is Nornfang!
Really bothers me tbh, simple continuity like that should easily be kept in check by 343.
