The Air Exchange, also known as the Air Conditioner, AirEx or the 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 Wasteland / Coast chapters, and before the Borealis, as the penultimate location of the third day. Prototyped and having all its maps made, it was never finalized in order to let the team concentrate on areas more fruitful for gameplay. This mod aims to deliver that cut experience, with updated visuals and gameplay, the mod is named ''Experience - Air Exchange'' because this is only one part of a bigger mod, i plan on re-creating entire chapters separately and releasing them as soon as they're ready.
