campaign coop

if you need advice, trust me on the last part try and getting there with eitheer a neddler rifle or a simple needler, most of the brutes dont have shields and also try the plasma gun and BR/neddler rifle combo, works great on elites

 

You have never been able to resume a Co-op game.

Your best option is to pick the mission you were on with your partner and finish it. That way if you have to stop you can pick the next mission and make progress.
