For the last trip, over 100 different cards were made (example on left). These cards each had an ability, and you could play them on other people on the trip. Super simple concept. 

You will start with a starter pack and will be able to earn more packs through challenges and winning games. This time, there will be some changes. 

Most importantly you cannot hold more than 8 cards that count toward your hand limit at a time. (unless a card you are holding says otherwise).

alcohol cards have a 30 min cool down on the person it was played on.
