I was in the US two weeks ago and went up and down with Uber. Five families, two with iPhones and three with Androids. I didn’t notice anything special. In fact, I took a ride cheaper than my Android friend. We were going back to the airport and to a certain terminal. They wanted to go to another. When he decided to change to my terminal, the price lowered to mine.
Can someone explain how community expeditions work?
I don’t have any friends and I can’t play timed events, because I have other priorities. Can I play this? Can I keep doing whatever I do on NMS while playing this expedition? How long does an expedition take?
