From BoardGameGeek:

Lost Cities is a card game from the Kosmos two-player series. The object is to mount profitable expeditions to one or more of the five different lost cities. Card play is quite straightforward, with a few agonizing moments sprinkled through what is mostly a fast-moving game. If you start a given expedition, you'd better make some progress in it, or it'll score you negative points. If you can make a lot of progress, you'll score quite well. After three rounds, the highest total score takes the day.

Rules are included for a four-player team game that requires two copies to play.
