Crime Boss: Rockay City

The achievement is pretty straightforward, but it can make the mission a bit longer/more frustrating, since the dinghy will leave, and you'll have to transport any remaining loot back to the van spawn. If you're at high heat and worried you won't be able to survive the cop rush, you can try doing everything in stealth, sneaking back the van, then just shooting an unsilenced weapon into the air. After a few seconds where everybody processes what just happened, the alarm will sound, and you can leave in the van, effectively pseudo-stealthing the mission.
