A recent video Focus Entertainment released confirmed that once co-op mode is here, players will be able to do classic Expeditions stuff like exploring together, sharing items, and completing expeditions with up to three friends. This Co-op mode will rely heavily on collaboration, so you’ll be able to set up camps, scan unexplored zones and nearby areas, and even rescue a stuck vehicle together. You might even need to split up and divide hazardous tasks to complete challenging expeditions.
These are all the details we know at the moment, but we’ll keep updating this wiki entry as more information becomes available.
