What are the criteria of becoming a target for turrets in Prey (2017)?

Question

I know that if you purchase too many Typhon abilities, you will be counted as alien by various Talos-1 systems like the turrets. And there is icon indicating how much you are transformed towards that.

I've purchased 2 abilities at a cost of 3 and 2 neuromods each. This caused the icon to fill to half. I concluded that I will be counted as an alien after purchasing either 2 more abilities or spending 4 more neuromods on typhon abilities. Yet after purchasing a single 2 neuromod cost ability I am getting a full icon.

I've also purchased few abilities from "Scientist" branch, for increased Psi capacity and for additional chips for Psychoscope, but I doubt those are counted as typhon abilities.

So, how is this actually counted? Or is the indicator not really indicating the exact process of transformation?

Answer 1

According to users in this thread, the general consensus is that it takes 3 Typhon skill activations to be considered alien enough to be targeted by turrets.

Third one will designate you as a target.

for me it was three.

Nah, I did three separate skills and they started attacking after the third for me as well.

For me it took 3 but some turrets attack me and some don't

3 but honestly turrets most of the time when you enter an area will be dead or you can just emp them then hack them.

Answer 2

On which difficulty are you playing on? On hard, even the first typhon ability (mimicry1) filled that bar 50%. I think it's either the number of typhon skills or the number of invested neuromods into typhon trees which determ the grade of typhonisation. Probably also the difficulty setting plays a role. Besides that, i have no clue or further information.
