Hall - Airlock

Avert Ye Eyes All Who Wish To Be Unspoiled!
The airlock allows astronauts and forklifts to cross through, improving accessibility across the colony. (However, heavy vehicles like the Dozer or Mineral Extractor cannot pass through.) The airlock becomes available on the next colony after you complete the Colony Planning challenge. We promise the top propeller is totally not an outside air vent.
