The skill of being able to move quietly and out of sight. When you are Sneaking, and doing it successfully, other people will be less likely to notice you – at a distance. If you get too close to a dangerous mutant, no matter how good you are at Sneaking, they will notice you. Active use. Use Sneak to toggle it on and off. You automatically stop Sneaking when you run. Your Sneak skill is rolled when you start to Sneak, and every minute after that.

Initial Level: Starting Sneak skill is equal to 25% + (1% x Agility). Average characters have a 30% Sneak skill.
