There is no penalty for falling onto a solid surface, but falling into bottomless pits or toxic pools kills the player character immediately. Characters can withstand limited damage but will die after sustained injury. These four characters can explore and interact with the environment. The player takes the role of Chell in the single-player campaign, as one of two robots-Atlas and P-Body-in the cooperative campaign, or as a simplistic humanoid icon in community-developed puzzles.
