THE SURVIVOR

Play as the survivor - John Kowalski. Walk around the ship and come face to face with the invisible monster. Heed instructions from the other player on how to avoid it and stay alive.

MISSION CONTROL

Play as mission control - Yang Sungbin. Even though the monster is invisible to the naked eye, security cameras can reveal his location. Take control of them to help the other player navigate the spaceship safely.

COOP CHALLENGES
