This game is not related to the story of the Half-life2.
Something goes mad because the human race failed in the
experiment, and it connects with another world.
The resident in the another world is crazy due to the mistake.
We should restore the situation.

As for this game, almost all are made only from the basic function of HL2.
Having fiddled with the code for the chapter unlock is the only exception.
You will learn the degree of freedom of the expression of HL2 is very high.

The game doesn't necessarily crash on level three it just takes a unusually long time to load things at certain points.

ALL YOU HAVE TO DO IS WAIT A LITTLE BIT IT DIDENT CRASH ITS JUST LOADING!

I used the text file fix but it always crashes on level 3 at the part with the train.
