Time to escape. You'll have two threats as you try to make it back to the main lobby where Samuels and Taylor wait. First, the human enemies are still roaming around.

If you see goo dripping from above, that means an Alien is ready to snatch you up the moment you walk under. If you see an Alien in the vent, don't think you're safe. Apparently the Alien has crazy magic and will appear all over the vents and roam the rooms.
