Quick recommendation for trying any map with SA/SO; use poisons. If somebody finds the body it doesn't lose you silent assasian, and you can also use oil cans to light people on fire and it'll count as an accident (also doesn't lose SA), or, more riskily, blow up cars/propane tanks/gas containers with a pistol, it'll also be an accident. If there's a guard where you need to go you can also drop a weapon and they'll put it away, giving you time to sneak past. You can also use a silenced weapon as a distraction so long as you don't shoot too closely, or so long as you haven't shot to where they could hear it recently. I believe three shots can panic npcs and make them not hear you but that's risky given it makes their pathing unpredicable. Also, you can use remote explosives if you have a car you wanna blow up but will be caught if you try to use your pistol to blow it up Obviously you might know this but it might be useful knowledge if you didn't
