This is a mini-expansion of the base game of Serengeti: A Race For Life. It can be used in the standard version of the game opposing 2 players as well as the multiplayer version. The Ranger replaces one of the Trail card in the players starting decks. With the Ranger players now have the ability to track animals located under rocks, right from the start of the game and without relying on an animal skill. They can also place it on an animal stack of their choice to protect it, potentially securing 2 points at the end of the game.
