When you first spawn into the game you're placed in a research facility and told to get to the test chamber. Unlike Half-Life however, Chaos Theory promptly drops you right in the thick of things.

------Storyline------------------------------------------------------
You are Gordon Freeman, a scientist working at a top secret government
laboratory. Your team is working on discovering the implications of
the Chaos Theory, but so far the results have been inconclusive.
However, you have the feeling that today's experiment may provide
answers one way or another...
------Play Information-----------------------------------------------
Deathmatch :No.
Single Player :Yes.
------Map Information------------------------------------------------
New Textures :One new sky texture.
New Sounds :No.
Known bugs :Dying and reloading during the first level can produce
problems with one of the models. However, as there is
nothing that can harm you during the level this
shouldn't be a problem. If you find any other bugs
please let me know.
------Construction---------------------------------------------------
Base :From scratch.
Editor(s) used :Worldcraft.
Compile Machine :AMD K6.

------Map Instructions-----------------------------------------------
Make a new folder inside your Half Life folder called chaos.
Next extract the files in this zip into that folder.
To run chaos you need to type the following line either in 1) a DOS
prompt in your Half Life directory or 2) by making a shortcut to
your HL.EXE, right clicking on the shortcut and modifying its
properties.
hl.exe -game chaos +map chaos
