Half-Life: Opposing Force Cheats (PC)

With the release of the Opposing Force CTF patch, there is now access to the ''kamikaze
penguin'', in the "wonderland"CTF map, and through cheating, in single player. Last I
knew, impulse 101 DOES NOT give you the penguin, however, typing in ''give
weapon_penguin'' does give you a pack of 6.

Start Half-Life using "hl.exe -dev -console -game gearbox.
  You may do this by modifying the windows shortcut properties for Half-Life OpFor and
adding "-dev -console -game gearbox" to the end of the "Target" (or file to run).

It's possible to take a good look at Freeman (I'm not talking about the various pictures
on the wall). At the beginning of Level 5 'We are not alone, listen carefully, you'll
hear a scientist encouraging "Freeman" to hurry. That's Gordon Freeman, the character
players portrayed in the original Half-Life!

  Try leaping into the orb to follow him to Xen. Unfortunately, you don't land over a
platform like he did. For more fun, switch to noclip mode and warp inside. You can get a
good look at Freeman then.

Start the game with the command
line parameter hl.exe -dev -console -game gearbox.
Now while playing you can press ~ to
bring up the console. 
It is also reported you can go to
the console by pressing ~ then type in sv_cheats
1 instead of having to do the command line
parameter above

Play original HL levels with OpFor weapons

All you have to do is start OpFor with the cheats on,
start a new game or boot camp, and type "map
c0a0" to start from the train, "map c1a0"
to skip the train intro, or "map t0a0" for the
hazard course.  Now, just type "impulse
101" to get all the weapons including those from
OpFor!!!!!

*WARNING- This can be slightly glitchy since the original
HL wasn't made for the OpFor weapons

This easter egg gives some problems, becaue I don't recall in which level I found it.
Anyway, somewhere, there's a filing cabinet/desk lying on the floor next to a picture of
Gordon Freeman. If you crouch and look at the desk, there's a picture of two kids. I
assume they're the kids of one of the programmers.

If you're really curious about the man in the suit, you can use the "noclip" cheat code to
walk throughs walls and doors to follow him. You will see him adjusting warheads and you
even can take a look inside his briefcase.

Just like in Half Life where the names of some of the people who made it were put around
the lockers in the locker room, the names of some of the people who made Opposing Force
are also in certain places e.g. at the start of the boot camp level look at the names on
the boxes beside the beds.

Load the game with the "hl.exe -dev -console -game gearbox" command line. Then while
playing a game, press ~ to display the console and enter one of the following codes to
activate the corresponding cheat function:

Approach the Boss of Opposing Force to hear backwards audio composed of the phrase "To win
the game you must kill me Randy Pitchford" when played correctly. Randy Pitchford is the
leader of the development team at Gearbox Software.

The 'trash compactor' in the "Pit Worm's nest" level is right out of starwars (look at the
doors and the pattern of lights above the doors).

Start Half-Life using "hl.exe -dev -console -game gearbox.
  You may do this by modifying the windows shortcut properties for Half-Life OpFor and
adding "-dev -console -game gearbox" to the end of the "Target" (or file to run).

  IMPULSE 101 - Give all weapons and ammo.

After you see that holographic thing of Walter talking about barnacles, you will enter a
freaky dark hallway with glass stuff containing alien beings. They are all labeled with
an ID number and are perfectly safe, except for 007. He scaped from his glass prison. If
you've ever seen James Bond, which you probably have, you know that James ALWAYS escapes.
This must be an easter egg because 007 is a lot smaller than the other ID numbers. I doubt
that it's a coincidence.

IMPULSE 101 - Give all weapons and ammo.
  /GOD - god mode.
  /NOCLIP - walk through walls/fly.

In the first level after the crash, a zombie throws a scientist through a window. If you
run around the zombie into the lab, you'll see a computer with an ultrasound image. That
ultrasound is of Randall Steward Pitchford III, the son of Randy Pitchford (the leader of
Gearbox Software who developed Opposing Force). He was born on January 8, after the game
shipped!

Approach the Boss of Opposing Force to hear backwards audio composed of the phrase "To win
the game you must kill me Randy Pitchford" when played correctly. Randy Pitchford is the
leader of the development team at Gearbox Software.

Start the "boot camp" and type /noclip in the console to walk through walls. Go straight
through the floor then and you reach a room with the hidden message "DMM 1999". DMM 1999
refers to David Michael Mertz 1999, the creator of the bootcamp.

Use one of the following ammo names with the "/give ammo_[ammo name]" code:
