Shadowrun Stealth Mechanics

Ever wanted to know just why the Stealth Suit ain't stealth? Is there no way to avoid direct confrontation? What are those silenced weapons and Silence spell good for? Weren't shadowrunners supposed to run in the shadows? Stealth mechanics were left kind of orphaned in the trilogy, but here these questions are brought to light in a reimagined Harfeld Manor run. No triggers were used to create stealth. And yes, you get a stealth suit that actually works.
