The first level you will complete in Carrion is the tutorial level called BSL-4 Research Ward. After this level you will arrive in the Frontier. You will need to navigate the Frontier to reach the entrance to the next location called Military Junkyard. To reach this location from the entrance to BSL-4 Research Ward head to the right and go up the wall with ladders and down the next section to reach a pipe going down. Go through the pipe.

In the next room move the cages out of the way and head to the left. Here you will see a glowing symbol on a fan. This path is blocked by wood that can’t be destroyed until we have a specific ability. This is a Containment Unit room which is optional to access later so keep that in mind. Ignore it for now and instead move the cage out of the way of the path in the ceiling above. Head left to reach the next room.

In this room head to the left until you see a switch on the left side of the room. Pull the switch to open the door below. Go through the open path into the room below. You will land in some water next to a pipe. Go to the left in this room then head down to the room below. Inside this mine room head to the left and pull the object out of your way so you can reach the next room. Follow the path until you reach a room that seems like a dead end. On the right side of this room there is a pipe you can squeeze through. Go into this pipe to reach the Military Junkyard.
