|This page is about the perk that appears in Fallout 3 and Fallout: New Vegas. For weapon that appears in The Pitt, see Infiltrator.|
The Infiltrator perk gives you a second attempt at a lock that you previously broke while trying to force it.”— In-game description, Fallout 3
With this perk, you give an additional attempt to pick a lock after failing a force lock attempt. However, since forcing a lock is never mandatory, the utility of this perk is debatable.
