DEVELOPER'S NOTE
As I'm now a dad, I don't have time nor energy anymore to continue OPEX support and development - at least for the moment. Thank you for your support and understanding.
- Gemini

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 OPEX for Opérations Extérieures - means External Operations). This new version now allows players to chose among several armies, depending on enabled extra mods !

• Entirely built with random parameters for generating unpredictible situations and unlimited replayability
  
• Custom menu at startup to enable/disable/set main mission features

• Advanced medical system (tweaked version of Psychobastard's AIS script) or expert (if ACE mod is detected)
  
• Optimized AI behaviour (thanks to R3F AiComTarget script)
  
• Move and transport almost every item (thanks to R3F Logistic script)
  
• Random and dynamic weather (thanks to code34 for his script - I modified it a bit so weather's evolution is depending on world regions)

• Live video feeds (thanks to BangaBob for his script)
  
• Little immersion tweaks: light sensitive map and NVG's optimized utilisation (thanks to Viperidae for his scripts)
  
• Map gestures with nearby players (thanks to dslyecxi for his script)

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 of those mods.

It's very easy, simply watch this video (please enable subtitles to get full detailed information).
