Hi NC,
You can adjust everything in data/Scripts/AI/init.AIX
Visual difficulty, Hydrophone difficulty, Radar difficulty, Sonar difficulty... for merchants or not merchants
Best is to create new folder with correct path (as i told you above) and copy paste your new init.AIX (so you don’t brake original TWOS) and put it in TWOS parts so you can activate it in TWOS Jsgme.
Or if you don’t do that, make a copy somewhere of your original init.AIX
Hope that helps
