Hello I just wanted to ask can we get the platinum in Co op for me and my friend ? I heard some trophies don’t pop for both of us is this fixed? I really want to know before starting the game please 
Only the HOST is able to get all trophies in multiplayer.
Two trophies “Out of the frying pan” and “Magnets, how do they work” do not unlock on MP for the second player and this is by design.
