**UPDATE 1/11/2017**Thanks to Takaitaua:
"On regular spy mission triping alarms or alerting enimies outside of the hacking area won't affect the achievement. So it's just staying undetected in the hacking area and extracting within 5 mins. The easiest mission I found was the spy mission on earth, managed to solo run it with a Loki with speed, power duration and efficincy mods."**UPDATE 5/1/16!**There is a much easier method to get this done if the mission is available! Completing a Spy - Invasion mission will also get you this achievement! Even better, there MIGHT be only ONE objective, and apparently you don't have to worry about getting detected!
I would like confirmation as to whether you can be detected in the actual hacking location, apparently you can be seen on the way to the objective. Credit goes to RED C0BRA 92.Previous method below:What you have to do: Pretty much what it says, except you can't set off ANY alarms outside of the objectives either!(thanks to Fooga for checking, assuming he WAS under 5 minutes
) So you have to be completely stealthed from start to finish of the mission.
Where to get: This can be done on any level spy mission, but pick one you're comfortable with and used to doing the puzzles so you don't have to spend any time figuring things out. I personally did this in
Martialis on
Mars. I chose Corpus because of the Grineer doors that can drain all your energy if you accidentally run through them!
Which Warframe: Loki/Loki Prime. There are a few other options, but Loki makes this flat out easy. Besides, if you're Loki, you don't have to worry about being seen if you use Invisibility and Decoy/Switch Teleport to get around laser walls quickly.
Other recommended Warframes: If you don't have Loki, then Ivara for stealth options is a possible substitute.
Any other warframes will just enormously increase the risk of detection.
Group or no group: This will also be FAR easier with a communicating team of 3 good Loki's!
If you are going to do this solo, get a timer and start a 5-minute countdown just so you know how much time you have left--it IS tricky to do solo unless you've had lots of practice.
What to bring: Enough ciphers so you don't have to worry about manually hacking any of the doors or objectives. That will save you a lot of time!
And some energy restores for replenishing Loki's energy/invisibility power.
I've included my loadouts for speed or invisibility on my Loki Prime below; I personally liked the ability to move very fast just to get to the objectives and extract faster.
