A week ago I decided to create a new profile, but this time I was going to unlock every cheat, today I was at the final part at the final mission, I killed scale and grabbed the keycard he had on his waist, I went to free the lockdown when I hear Taylor (the nickname I made for my teammate) tell me "You have to go back and complete all objectives before you can do this." I pressed the menu button and every mission was completed. Except for grabbing the keycard on scale, I was very confused. I then went back and retried the mission again, again, and again. Each time using the backup units to re-grab the keycard. I have been doing this for hours and it still wont work. My patients was beginning to be tested when I realized found out that it wasn't scales keycard I needed to unlock the lockdown, although it could be more clear that you needed to go to the dead bodies for the key card, because I did not once get educated about it from a single person, I figured it out when I was exploring the base.
