“The warrens of the Divide have taught you to keep your head down. Your movement speed is greatly increased while sneaking in light armor, or when wearing no armor at all.”— In-game description
Effects[edit | edit source]
Movement speed is 25% increased while sneaking in light armor, or when wearing no armor at all.
Notes[edit | edit source]
- This perk works with Implant M-5, for a net decrease of only 14.5% movement speed when sneaking compared to walking. The speed bonus is applied to fast traveling while in sneak mode, reducing hunger, thirst, sleep, and elapsed time generated in Hardcore mode.
- The Travel Light and Light Touch perks work very well with Tunnel Runner.
- With Silent Running and Tunnel Runner, one can sneak up to someone very quickly and quietly.
- This perk has the highest Agility requirement for a perk, with a requirement of 8 points.
