Find the lab controls
On floor 4, look for the round red hatch near the stairs with the pipes. The interaction prompt reads EXO LAB AIRLOCK. Try to open it and you’ll see LOCKED REMOTELY. Find the terminal on the desk beside the locker marked STORAGE LOCKER in yellow.
Open the hatch
- Open LABCTRL.EXE on the desk terminal.
- Select UNLOCK A to lower the ladder.
- Select UNLOCK B. The B control changes to a round hatch icon.
- Follow the short, curved passage and walk through the open circular hatch.
The lab’s sample door has its own keypad upstairs.
