In Shift 4 you're in control of an astronaut whose ship was attacked by a giant squid, forcing our protagonist to make an emergency landing at the closest planet. Waking up to find your family members missing, you decide to explore a deserted facility nearby and search for clues about their current whereabouts.

This particular episode is a little more challenging than previous releases, since players are required to switch between two or more characters often to solve some of the harder puzzles. New gameplay elements such as gravity and contact-sensitive switches are introduced at a steady pace, which is a boon considering that the map is a lot less linear and there is a bit of backtracking to do as well.
