Together you must travel to the Arctic, rescue Judith Mossman and work together to find and secure Aperture Science's vessel Borealis, before it falls into Combine's hands. Aside from the classic obstacles, you'll also face the harsh polar climate along the way and in order to make it through these dangers, you'll have to cooperate.
