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.

Like a Boss Achievement

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".

    I saw a "no detection" speedrun, and I seem to remember him getting the white-arc warning several times and radio comms between guards. I don't have the link on me, but a quick youtube search might turn up a quick run you can take a look at and draw conclusions from.

  • I don't know of a "Like a Boss" Achievement or Trophy for Ground Zeroes. Are you talking about the "Hero" one (Cleared all missions (including Side Ops and Extra Ops) with a S-rank) or is it about some DLC I don't know about?

  • @Nolonar I don't know how exclusive the achievement is on different platforms, but I know this is on Xbox One and it's a Featured Challenge actually. Where this challenge doesn't reward any points but it's for early adopters of the game since it has a time limit. Got 26 days left to finish this challenge or it's gone from the challenge list. Not a DLC at all, I've edited my question to include a picture of the challenge

    I see. This seems like a Xbox One exclusive feature alright. I can't give you a definite answer, but I'm certain the white-arc and radio communications don't affect your progress. Not so sure about Reflex, though. However, I believe you can disregard stealth in Side Op 2, since that's a shooting mission and enemies already know you're there.

From my experience with Ground Zeroes

Undetected is when no one knows you are there. Let me explain:

If an enemy sees you but it doesn't activate reflex mode (normally the white-arc on the screen appears) you are still undetected!

If the Reflex Mode is activated you must take him down within the reflex or you will become detected. For your challenge specifically you can't kill him since the challenge requires 0 kills. If you succeeded in taking the enemy down you will still be undetected!

While I was playing if they find bodies of other soldiers you will become detected. I once forgot a body on the floor and didn't think they would care but if you give them time, they will call CP for support depending if the body is from a dead soldier or a knocked out soldier.

I hope I was able to answer your question the way you wanted.


from what I know of Metal Gear, undetected always ment no enemy contact, which means that supicious noises/person and the white arc does not count towards your detection stats. even if I had some supicion chatter on the radion in one of my stealth gameplay, it gave me the stealth playthrough note in my stats. since I do not play with reflex mode, I don't know if it will count as detected if a guard sees you and you silence him.
