  1. Okay, the text is taken from the submission. The details were sent to me. Thanks kkaizi.

    I’ve played about half thess maps and I am having fun. It’s good so far but as kkazi says, it’s quite hard.

    Enjoy and don’t forget to rate it when you have finished it. I will.

  2. I’m not kkazi (lol) kkazi is the email of the author, I’m just the guy who submmited this mapackage.

    And I was about to write “B-Dama” but I thought it was server hosting the site.

    Have fun people.

  3. I would like to try this mod, BUT I don’t understand Japanese!! Which folder do these files go into?? My HL1 or the Gearbox (OP) folder??

  4. On mine its its
    C:\Program Files\Valve\Steam\SteamApps\username\opposing force\gearbox\maps

  5. Unzip .bsp files to gearbox/maps

    Unzip the .nod files to gearbox/maps/graphs

    Open Opposing Force console and type “map force300″

  6. -SPOILER-SPOILER-SPOILER-SPOILER-
    -SPOILER-SPOILER-SPOILER-SPOILER-
    -SPOILER-SPOILER-SPOILER-SPOILER-

    I think there’s no end sequence, so, when nobody is shooting at you at the map force309 that’s it, you are done.

    -END OF SPOILER-

  7. Thanks to both of you guys #4 & 5, since I only run the Sierra version, senator33 your instruction filled the bill, it works fine!!
    Kinda funny, I’ve had these addons since they were released but never used extra maps/mods with them (except for HL1) Oh well, better late than never!!

    Does anyone know where to get a Walkthrough. I’m stuck in force305 after falling down to do battle with a Gargantua and two Masters, I used the barnacle to climb back up. Now I,ve investigated every nook, cranny, and ceiling tile and don,t know where to go.

  9. Spoiler alert
    David4255, There’s a cable/rope hanging down. And a cracked door.
    If you get any further, like to the power generator, give me a clue how to turn it on. Please!

    Afro-dude – yes there is a clear end sequence.Very very good mod. Great design and gameplay. Very hard (but not annoying) clever puzzles. Huge environments to explore. Extended battles with well thought out enemy placement. Enormous end battle against an Apache, and an Osprey dropping Black Ops in different places. The best designed battle of its type I reckon.
    4.5/5. Only disappointment was that it ended!

    I’d like to add that there is an end sequence. It’s been ages since I played this, but if I remember correctly, once you have defeated all the enemies you should use a radio located in a small building next to the aircraft landing pad. The radio won’t help you if enemies are currently attacking.No worries if people missed that though, I don’t think you missed anything other than end credits and music.I remember really enjoying this mod. I found it very hard… but that may have been because I was trying to keep all of my soldier allies alive, I built up a massive army of friendly soldiers. Some players dont’ care about allies though, they just use friendly soldiers and human shields, hehe, so such players may find the mod easier. I strongly recommend this well-made Opposing Force mod.

  12. Think Twice

    I tried this one. Briefly.

    There’s no health counter, and once I pick up a new weapon, I can’t access any of my other weapons. Also, game crashed to desktop during an ordinary, unscripted sequence of play.

  13. Play It Now!

    Great mod, the mapping is almost super and gameplay is brilliant. It’s a pretty large mod too, few maps, but they are large as *BEEP*! However, it’s a pretty hard mod (at least on hard mode) and sometimes you can be out of ammo on a weapon for a pretty long time. Get this mod, it’s as good as Nuclear Winter.

  14. Cant download ,repair link!!!plsssssss i want play toooooooooooooooooooo

    Could somebody help me get started? I put the folder in “C:\Program Files\Valve\Steam\SteamApps\username\opposing force\gearbox\maps”. I restarted steam, it is not listed on my games. So I then started “Opposing Force” and open my console, type in “map force300″ without the quotes. It still didn’t work. :(
    What am I doing wrong?

  17. Cant launch games from the gearbox folder it has to be done in the HL1 folder.I’ll upload what I just made that you can just drop in your half-life folder for a steam install.Gimmie 15 minutes and it will be in this thread.

    I really need help! Im stuck in an area with a water river thing (inside) and theres an elevator in 02 area and there are 3 levers that control A, B, and C. they just move these catwalk things up and down and i really dont know what to do. Please help

  22. You need to increase the water level and that is done by shooting the blockade in the upper wall where water is supposed to come down.

  23. Im in the pit where you fight the gargantua and the 2 alien controllers. But now where do i go?

      You must go up on the ladder and throw the grenade in to the place with black pipes. after the explosion you must go down, activate the generator and go back in to the lift….
