While Far Cry 5 is a lot of fun in solo play, the game's expanded online gameplay is likely where most players will spend their time. Co-op play is where Ubisoft's next open-world game really shines, and after the game's tutorial mission, the entirety of your time through Hope County can be played online with a friend. Whether it's diving into several stunt-driving missions, base-raiding, taking down some of the key members of Eden's Gate, or hunting animals, you can do it with a friend.

In the above video, Aaron Sampson and I got to play through Far Cry 5's opening and experience the early hours in the open world. During that time, we took part in the many activities that Hope County has to offer. But we wanted to go a bit further, so we took some time to test all sorts of stunts and features associated with co-op, and whether it could all work in ways that most players will expect.
