Half-life DYKG thread

[Liraxus]

Ok, let me say that their are a RIDICULOUS amount of interesting facts about Half-Life and Half-Life 2, but i plan to make this an entire thread about Half-lifes' facts. You may post your facts but try to limit yourself to at least 3 per post. I want alot of people to contribute.

Lets Start.

Near the end of Half-Life 2, during the final ride to Breen, you can see 2 synth's on conveyer belts that don't appear anywhere else in the game. These were synth's that were cut from early versions of the game.

The Borealis was originally called the Hyperborea and was to be visited at the start of HL2.
