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.

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.

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.


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.


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.


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.


Use the following map names with the "/map [map name]" code:


There's a computer in the room where you meet Otis for the first time that looks like it's running MS Windows. If you use the keyboard five times, the computer will crash with the "blue screen of death."

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.

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).


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!
