Life Underground, a game developed by the Game Innovation Lab at the University of Southern California, takes players on a journey into the depths and extremes of the Earth, and it’s available to download! The game is an interactive outreach experience for 7th and 8th grade classrooms. The goal is for students to visualize microscopic life at a range of terrestrial and extraterrestrial subsurface conditions. Students take the role of a young scientist investigating extreme subsurface environments for microbial life. They will navigate through extreme conditions, including those of temperature, pressure, acidity, and energy limitations, and they will begin to recognize what characterizes life in this context.
