Master of Unlocking
Master of Unlocking is the silver trophy for opening all 13 shiv doors. Each locked room uses up a full shiv and hides parts, supplements, ammo or a health kit, so it pays to keep blades and binding on hand.

Good to know
- Grade: silver.
- 13 doors: two in The Outskirts, two in Bill's Town, four in Pittsburgh, one each in Tommy's Dam, The University, Lakeside Resort, Bus Depot and The Firefly Lab.
- A partly used shiv cannot open a door.
Easy to miss
The Lakeside Resort door is behind a wooden gate past a motel window. The Bus Depot door is down the right-hand tunnel past the workbench. The Firefly Lab door is beside the information room behind the sixth-floor reception desk, and Stewart-Seume's pendant is inside.
