Well its my friend actually. We just completed Leon's story mode with me as the host but playing as Helena. On my records it states that i've completed the game on Professional yet on my friends it states hes done it all on normal? Can anyone shed some light on this situation? The difficulty was on pro btw not normal.
Apparently, the difficulty of a coop game is set to the difficulty you previously selected. So if you were playing on normal before coop and your friend was playing professional when he joined your game your difficulty would be normal and his would be professional.
If you both want to play on the same difficulty, start a campaign, pick your difficulty, quit out, and then join your friends game.
A coward turns away, but a brave man's choice is danger.
