Half-Life Wiki:Featured article queue/45 2009



The Air Exchange, also known as Air Conditioner, AirEx or Combine's atmospheric reprocessor, is a location and chapter cut from Half-Life 2. It was to be set after the Depot, at the end of the Coast chapters, and before the Borealis, as the penultimate location of the third day. Prototyped and having most of its maps made, it was never finalized to let the team concentrate on areas more fruitful for gameplay.
