Talk:Upgrades data for technicians/@comment-36945566-20181018171406/@comment-37335013-20181101221829

All I can say is that I did all upgrades using Fox, except the scanners (upgraded by the scientist at Yantar). I frequently returned to Fox as I managed to make all repairs by him as well.

I upgraded my first RPG lot before that mission, but the sniper rifles also needed the same schematics that I found later in game. As I had not enough money to fully upgrade the sniper rifles at first time, I could see the upgrade tree several times.

_Not much_ before the Heli's task, the upgrade was not YET available, then I returned to Fox after that mission and I could make the upgrade.

I definitely did not pick up any items as it's quite visible when the game prompts "Item lost" when adding a flash drive to your PDA and that simply did not happen for this upgrade data.

I am sorry that I could not provide better source.

My way of playing the game was: I swept clean all areas and scanned for artifacts, before proceeding with the storyline.

You can tight down the area where the info could be found. I did not visit the non-accessible maps before getting the Heli's task, but fully discovered all locations up to that storyline element.

I also could not find upgrade data to make the "Adjustable Range Finder" for the SVD. It can be a bug as all other weapons can be upgraded with that data.
