Backtrack and find the entrance Zone used
From Create Your Own Story
You, Johnson, and Thompson backtrack into the urban ruins. Johnson uses his PAD to locate the entrance, so the journey is fairly easy. As you approach the entrance however, you hear a garbled message over your radio.
"Location... All Crewman... Repeat: Code Red...."
You look at Johnson and Thompson, and the three of you immediately begin sprinting to the Cap'n's location. You can hear it as you get closer, the Cap'n yelling for the crew to stand down. Your HUD informs you that this is going on around the next corner.
