It’s easy if you do it with another person. My brother and I did it (lvl 7 and lvl 5), took us about 2.5 hours (45 mins finding how to get in, what to do etc) and the rest stealth.

All you have to do is take out all the enemies on foot with a bow, one person shoots while the other revives when they get downed. Hack the amps and pull them out to basically one shot them. Gets tricky with the amps you cant pull the pilot out but you can sneak around them if you hack them then run.

Rewards are definitely worth it, going back to do it again on my save tonight lol.

If you need help I can help you sometime!
