Fun fact, at one point in HL2's development, the planned storyline was the following (this is based on a picture taken of a development board at Valve): Train ride: City 17 Station Terminal square Arcade (or other) Back alleys/Factory Breen plaza Sewers Canals Quarry Ravenholm Eli's Base Junkyard or Wasteland The Lighthouse (Train Ride?) (Alyx+Train?) Air Exchange Borealis Kleiner's Lab Factory Breen plaza City Street Gate to Inner City Inner City Citadel Interior Notice how Kracken Base and Weather Control were already gone. This was from late 2002
