In Enclosure, players act as a researchers studying the adaptability of the creatures that were newly created with 'Biohack'.
To ensure the highest quality of research data, each player has to fulfill a randomized set of research objectives. These objectives will dictate which set of creatures the players will need to have or to position in the various habitats they are testing.
After a player completes 12 research objectives, the game will end and the player that has the most EP will win the game.
