Playing single player missions together
If you save game during a multiplayer game by pressing F3 and load with F4 and if your opponents do the same thing, you guys can play single player missions together? The goal and chests will still be there.
You have to save game of whatever single player level every player wants and load that same one
Or you can just change the multiplayer mission with a different mission to make it easier lol
Players don't share items so most levels are impossible
