No fog mod, that deletes it completely from the game and expansions.

[Materia]

Hello, Im looking for a no fog mod for base Ghost Recon, as well as Desert Siege and Island Thunder. I know there is something like that, because I used it, but I cant find it anymore, anywhere. Would be good to play the game once again, and again, and again etc. with it.

Welcome to the forums, Materia!

Several Ghost Recon mods change fog settings to achieve more realistic longer viewing (and drawing) distances. There are two mods that focus exclusively on exactly that (without changing anything else):

Fogless (by Ryan243)

Fogless (by NovemberRain)

Then there are more complex mods that - next to more realistic fog settings - come with a host of other features and content, e.g. Realism Update incorporates fog settings from both aforementioned mods and adds a huge amount of other realism enhancements. And if you don't mind me advertising my own mod, Heroes Unleashed features its own fog settings for all Ghost Recon, Desert Siege, and Island Thunder (plus many other third-party) maps, as part of its efforts to maximize realism in all aspects of the game.
