I swear, Stealth is broken in this fucking game
I have every perk related to stealth maxed out, I'm wearing every possible invisible space suit / helmet combination PLUS that stupid tactical stealth suit, and basically every turret fire at me from miles away.
If an enemy is above level 10 they spot me almost instantly as well. Very frustrating.
It took me AGES to max out the perk that requires you to stab 75 NPCs because it doesn't work!
