I am really trying to complete the "Like a Boss" Xbox One challenge: Clear all missions (NORMAL and HARD) within the time limit without being spotted and with 0 kills.
In order to achieve undetection do I need to be completely unseen? That means:
- No white-arc warning on screen,
- No radio communication between guards ("CP, this is Zulu X, I saw a suspicious figure, going in to check out."
- Status alert remains Normal,
I keep on restarting the mission not knowing whether I have or have not compromised the challenge.
Please specify what criteria I need to follow to be "undetected".
