If you have a second controller you can run through coop by yourself essentially. :slight_smile:

Yup, that’s what I did because the online co-op campaign is buggy.

I would recommend what others suggested (split screen) but if you MUST need another player. My gamertag: OperatorSnek (Same as my Waypoint)
