You and two of your teammates, Holiday and Jin, survived the explosion of the secret laboratory and you're now on your way back to base by helicopter assuming the day had been saved and Alma and Fettel would be dead. But as always, nothing seems as it is and suddenly Alma boards the helicopter and it crashes down. Separated from your teammates, you make your way to the extraction point not knowing what awaits you...
