Caduceus is an online puzzle and adventure game that takes players to a mythical world where they must find a cure for a plague that’s sweeping the land. Players of all ages, but especially those in middle school, can “game for good” as part of the Generation Cures project, learning about science as they help to raise money for critical pediatric medical research. The “In the Classroom” program is ideally suited for classroom lessons and fundraising projects.
