Payday 2: 10 Crucial Tips & Tricks The Game Doesn't Tell You
8. How Concealment Works
Every gun, weapon and your armour comes with a concealment rating, and this is integral to any stealth'ing you want to do. If you rock up to a jewellery store with a missile launcher and some full body armour then yes, that detection rating is gonna mean guards and cameras will spot you a mile away.
The higher your concealment stat on weapons and armour, the lower the detection risk and the likelihood of you being spotted doing something naughty. The lowest your concealment can be is 3, highest 75.
The best way to get that low stat is by stripping down a CAR-4 to be a pure stealth gun with very little damage, and never using it! Take a decent silenced pistol for any actual shooting and go all in on stealth missions, restarting if you fail rather than taking any “Just in case it goes bad” back up weapons.
