Me and my friend tried it out, but the second mission when you need to load the map. Only the host can load it sucessfully while the other player is stuck at the loading screen. The host can still choose both spawns and start the mission. But by doing that the second player will not be able to press buttons, since in the game only the host chose the spawns I would presume. There is 2 ways to fix it. Either fix loading screen stuck problem or let the host choose the spawn of both players....
