About advent security towers
in a "kill VIP" mission, I've hacked one of the 2 turrets succesfully and it gave me "Reduce enemy will by 50%".
But then, the second turret became unhackable. It was still rotating with red lights, but no matter how close I was (even melee) it was impossible to hack (no hack symbol appearing on my specialist actions).
Is it normal or a bug ?
Solution 1:
This is normal. You can only hack one security tower per mission. So you should check which tower gives you which bonus and then decide which one is the better deal for you.
