Corps Of Discovery by Jay Cormier, Sen-Foong Lim

Corps of Discovery is a 1 to 4 player co-operative survival game where you play as Lewis, Clark, and the rest of the Corps as they explore America...and kill monsters! Using a unique map contraption, slide a new map into it every time you play and explore by removing tokens. Find resources you need to overcome challenges as each terrain has specific rules on where it's located. 
 
 Game box comes with two chapters: Fauna and Flora - each with their own unique components and objectives. 20 maps come in the box and new maps can be downloaded and printed for unlimited replayability. 
 
 Choose which character and which Gear to equip as each offers an ability you can use every day. Be warned though - overcoming challenges isn't your goal - finding and killing monsters is! That said, if you are ever told to drink water and you don't have any, or if you can't eat food at the end of every day, then you all lose the game! Survive long enough to find the monsters, as well as figuring out how to kill them, and you'll win the game. Do you have what it takes to join the Corps of Discovery?
