For this thread well share our thoughts on missions we've passed stealthy. Everybody can give advice, share your annoyances, and missions that you can't seem to pass smoothly.
I'll list some mission I've passed stealthy and share my tactics.
( Success) Jewelry Store - For this mission I was with a group and we all had mics. I had one guy positioned outside to keep bystanders at bay. While me and the other guy took care of the security guards outside. Since I had the intimidate perk I made them cuff themselves. Afterwards me and my partner rushed inside got the people down to the floor, and I killed the last security guard in the building. Since I had one guy outside he stop anybody from noticing the robbery. Then it was smooth sailing I got all the jewelry and everything went as planned.
(Success) Framing the Frame - Doing this mission by myself was easy. Since I had the intimidate perk and being convincing perk. All I did was sneak into the back bathroom. Took my time to disable any cameras I've seen, wait for a guard to come to check the camera, then I'll make him cuff himself. If a guard doesn't listen to me I'll kill em, and since I got the convincing perk I can answer his pager without being too suspicious. After I took care all the guards and cameras getting the paintings was a breeze, and when day 3 came I basically did the samething as I did on day 1.
I will list more heists I've done stealthy and talk about the heist I've failed later on. As of now I'll let you guys post your experiences. You can share your thoughts, or just name a heist you've passed with stealth.
