10 Unbelievably Scary Video Game Locations Discovered By Hackers
7. The Secret Hazard Course - Half-Life 2
A year before Half-Life 2 finally hit stores in 2004, a hacker stole and leaked an unfinished version of the game, which included among it the source code and more than 1,300 map files.
One of these maps was "Hazard1," a secret hazard course of-sorts in which players must work their way through a series of increasingly surreal rooms full of unnerving imagery, culminating in a meeting with G-Man himself.
Hilariously G-Man even tells you, "You're not supposed to be here," and that's because Hazard01 was never actually supposed to be seen be players at all.
As Half-Life story writer and level designer Marc Laidlaw confirmed, Hazard01 was created as a test map for the team at Valve to test out strange environmental effects, mostly related to Gordon's encounters with G-Man.
Despite being totally unrelated to the canon storyline, it's nevertheless one of the eeriest pieces of Half-Life gameplay out there. It doesn't quite beat Ravenholm, though, admittedly.
