OPEX is an immersive, realist and fully dynamic task generator for ArmA III military simulator.
The first version was initially introducing the French Army fighting against terrorist organizations all over the world (hence the French name Opérations Extérieures - means External Operations). This new version now allows players to chose among several armies, depending on enabled extra mods !
I have to be honest, OPEX has totally be inspired by MSO from ArmA II. After I have tried it, I thought the idea of a dynamic task generator was brilliant, but some features were not perfectly fitting to what I was expecting for and some others were missing. So firstly, I tried to customize the original MSO but finally I chose to rebuild everything from scratch.
After more than 8 years of development (yeah, really !), and even if there are still many things to do, it's now time for sharing all I have did so far !
Made by Gemini
Mission that required more than 2000 hours of learning, experimentations and development (project started in 2012)
SP and MP compatible (from 1 to 50 players)
Unique immersive and realist atmosphere

Dynamic civilian life with custom interactions (talk, search, arrest...)
Dynamic AI activities: patrols, ambushes, reinforcements, suicid bombers, roadblocks...
Dynamic reputation: take care of the local population or it may rise against you
Gather and exchange intel to recruit AI teammates and to get extra supplies, vehicles, supports...
AI improvements: ability to assign/unassign NVG/flashlights/silencer depending on daytime and behaviour, ability to board into nearest static weapon...

OTHER GAMEPLAY SERIES
REQUIRED ADDONS / DEPENDENCIES
OPEX can be played without any mod (vanilla game) but in order to enjoy all the features and possibilites, it is highly recommended to subscribe (for free !) to the official mod collection. If you don't have a large storage capacity and a very high speed internet connection, you can also select only some ot these mods.
Don't hesitate to share your feedbacks, your suggestions and to report any bug or issue you may encounter here on the official BIS forum, or on Steam.
Picture "pictures\overview.paa" not found at startup when joining server despite the picture is present in the mission folder, I don't know how to fix this.
Some vehicles are sometimes exploding when spawning because collision detection is not reliable at 100% despite I'm trying to improve BI's commands as much as possible.
Ambient AI animations may sometimes be weired when playing on MP.

This mission is dedicated to the memory of Faiavan (1979-2018). I only had the chance to share one or two missions with Faia but his accent, his good mood and his sense of humor made me feel good. May he rest in peace.
