Reach 20 hits in a single Volleyball rally

In order to get this trophy/achievement you must start a game of volleyball and volley back and forth 20 times without the ball hitting the ground. So get a partner or two and start a match. It may take a few attempts to get a volley of 20, but it shouldn't prove to be too difficult.

I would recommend playing with a full group of real players so you don't have to rely on the AI, who can be pretty unreliable in terms of hitting the ball back
