Following the Louisiana Purchase, President Thomas Jefferson needs your help. As a Corps of Discovery leader, you'll conduct the expedition throughout the unexplored interior of North America with the goal of finding a convenient passage from the Missouri River up to the Pacific Ocean. Throughout the journey, you will encounter and examine a lot of new plants and animals, but most notably - a lot of native American tribes of the great plains. Using violence or diplomacy you will strive to survive, and if you're lucky enough - your expedition will succeed. Beware of Grizzly bears, barking squirrels, and the little people of Pryor Mountains.
