Start Half-Life using "hl.exe -console". You may do this by modifying the
windows shortcut properties for Half-Life and adding "-console" to the end
of the "Target" (or file to run). The /GIVE command works if you start the
game with the -dev -console parameter, and that the God mode cheat and map
change cheat only work with the -console parameter.

This will let you access the console using "~" key. You may have to type
"sv_cheats 1" in console first. The following commands are available in console:

Code Effect

/fly - flying mode
/GOD - god mode.
/NOCLIP - walk through walls/fly.
IMPULSE 101 - Give all weapons and ammo.
/MAP xxxx - go to map xxxx. Map names are of the format c#a#,
(c1a1, c2a1, etc).
See the map list for names of all levels.
/GIVE xxxx - give item xxxx. The following items are available:

Start Half-Life with the following parameters: Hl.exe -console -toconsole -dev

You should see a constant flow of text for everything you do. Use a low damage
weapon on a scientist, and then run after him. Once he is trapped somewhere
click the 'Use' key on him. The text should say something like "I won't follow
you, you evil man".

If u r having trouble with Gornach then this is what u do. first u shoot her
for a while then she will run. follow her into the cave.then when u get out
into the open run out of the cave and into the hole but careful becuz there
is only 3 places u can land. 1 of them has a healing pool in it, 1 of them
has a thing that jumps u high, and 1 had nothing. stay there out on the ledge
and she will come by a few times. when she does shoot her! she will run eventually.

Then u will drop down into a place that is very queer. go behind the big arch
in the bottom(u will c what i mean) and hide there. she might shout out a few
babies but if u hold crouch and go under the arch a lil bit they cant hert u.
then keep shooting at her, eventually she will fall in with u but u might just
have 2 shoot her a few times. good luck :)

Interlooper, hidden med-kits, health and ammo:

In the 3rd part of 'Interlooper' , where you see a Garg (a huge monster who can
burn you) crushing rocks ans stones to be able to pass through, there will be a
small hole behind. When you enter it, you will find a small waterfall, and plenty
of water on the floor. When you step into it, your health will recover gradualy.
Before entering the hole, look in the direction where the Garg crushes the huge
rocks. You should be able to see a sort of staircase, but smoother than a staircase.
In fact, it can be described as a slope. It'll be on the left, stuck to the wall.
Climb on it, and when on top, look to the right. you'll see a tiny lighted room
with med-kits and ammunition packs in it. Duck, and crawl into it.

Best way to escape barnacles:

If you get trapped by a barnacle (those things with the long, sticky strings
hanging down), quickly pull out your crowbar and attack the creature to kill
it in one hit. Don't try this if the barnacle is on a high ceiling, though, as
you'll take quite a bit of damage from the fall. You can also equip your crowbar
and allow yourself to get dragged up to kill the barnacle and save some ammunition.

Hidden room:

After you shoot the missle in single player mode, turn on no clip, and chase it.
But let it go completly out first then leave. As soon as you get out of the area,
turn off noclip, and turn on your flash light. You are now in a hidden room.

Monster creation:

You must be within the loading area of the desired monster for this cheat to work.
For example, you cannot load up Barney while fighting the Nihilanth. Enter give
<monster name> and the corresponding monster will appear.
Note: Activate the /noclip first, or you will be stuck inside the monster.

Zoom on every weapon:

Get the Crossbow in single player mode and do a quick save with the weapon that you
want to zoom in with. Change to the Crossbow and zoom in, then quick load and your
other weapon will be zoomed in. You can now change weapons and they will all be
zoomed in. To come out of zoom, change back to the Crossbow and press the second
fire button until it zooms out again.

Look inside G-Man's briefcase:

To look inside G-Man's briefcase, first enable the noclip code. There are two ways to
do this trick. The first is to start from the beginning and ride the train until you
see the G Man for the first time. He should be in a train next to the one you are in
towards the end of the ride, by the radioactive water. The other way is to go through
the train ride, then walk around the halls of the laboratory to find him talking to
a scientist. When you do this, go towards the G-Man. Get as close as possible to his
briefcase without going through it (this make require a few attempts). In one side,
there is paper, three pencils and a pistol. On the other side is a computer with a
message and a picture of the G-Man. Note: When doing this where the G-Man is talking
to the scientist, you will not be able to understand what the two are saying.
