Crime Boss: Rockay City

Just a note for mental preparation: this, of the 4 major campaign heists, is the only one aside from "Import Export" that you CAN complete entirely in "stealth." Shut down the cameras, carefully lure and subdue all of the guards, then initiate the heist (by holding LB), and keep an eye on the entry doors. You'll want to intimidate anyone who walks in as well as NPCs standing right outside (the drill seems to spook them when the spawns on the second floor). Get everyone tied up, and while keeping an eye on the front doors, move all your hostages to areas out of view from the entryway. If all of this goes right, you'll be able to transport all your riches easily. You could do this solo, but it might be really difficult to tie all the hostages up without allowing anyone to run - so I always go with Baker and my 3 cheapest team members.
