The Surge 2 takes place after the destruction from the first game. The city of Jericho has been evacuated and a large wall has been erected to keep those infected with a techno-nanite disease isolated from the rest of the world. Your character (who can be a male or female) crash lands in this city and is one of two survivors. The other surviving passenger is a young girl named Athena who is related to the president of Creo Institute of Technology.
