    Multiplayer Co-op Campaign (up to 14 players)

    The year is 1968 and the Vietnam War is reaching its peak. As elite MACV-SOG reconnaissance team "Columbia", your mission is to stop the flow of materials down the Ho Chi Minh Trail. Your team must engage in clandestine operations in Laos and Cambodia, hunting and destroying the PAVN 559th Transportation Group and its numerous security units. Feel the adrenaline rush of operating deep within hostile territory while the People’s Army of Vietnam try to track, locate, and overrun your team.

    Written alongside former recon team leaders from the US Special Forces elite MACV-SOG, this fully voice-acted campaign consists of 6 highly replayable co-op missions featuring dynamic difficulty and drop-in/drop-out multiplayer capability.

    Although the Co-op campaign is not designed for singleplayer, progress saving has been added while playing in "multiplayer solo mode." The 1.2 update adds 2 new campaign missions, and the team RTO can now directly call air support during Prairie Fire emergencies in parts of the campaign.

    Multiplayer - 17 Scenarios & Bonus Mission

    S.O.G. Prairie Fire adds 17 new multiplayer scenarios to Cam Lao Nam for Arma 3's official game modes Warlords, End Game, Zeus, and Escape.

This optional Enhanced Multiplayer Menu contains an improved interface with many new features that help you find, choose, and join multiplayer games featuring the Creator DLC.

    Additionally, there is a fully narrated singleplayer Showcase scenario for both PAVN and MACV that introduces players to the world of jungle combat and historic warfare.

    The bonus helicopter mission “Ash and Trash” can also be enjoyed as a singleplayer scenario.

    Sounds & Effects

    Hear your enemies whispering as they approach in the dark, yelling as they rush to overrun you, and crying out when they’re wounded. Immerse yourself in the hair-raising sounds of bullet cracks, explosions, and softly approaching footsteps. Experience the jungle like you never have before with realistic sounds of weather, wildlife, and disturbed vegetation. Every single sound and effect has been meticulously reproduced by the author of the JSRS Sound mod to offer players a truly captivating experience.

    The 1.2 update saw many sound effects updated and improved, along with the addition of an immersive voice pack each for Australian and New Zealand forces.

    The 1.3 update again overhauled many of the sound effects to make combat feel more dangerous, and many visual fx were completely reworked to bring a fresh immersion to the battlefield.


    The vibrant soundtrack features 21 rock and blues tracks by originalsas that take you back to the 1960’s. Played in vehicles or heard from the placeable FM radio, the tunes are complemented by original Armed Forces Vietnam (AFVN) news and adverts that ran at the time. Included as well are 16 cinematic tracks by FabianKreutzerSound, which were composed with authentic Vietnamese instruments and designed to augment the Vietnamese and Laotian landscapes.
