Infiltrator

Mechanics
Infiltrator is a tier 4 Ghost skill which improves your breaching skills, mainly doors and safes.

The basic version lets you use a melee weapon to open non-reinforced locked doors while the aced version increases lock picking speed by 100% and gives more concealment.

Strategy
This skill is mostly intended for stealth but the regular version can be used for loud to open doors quickly and the aced version can help people pick locks faster so they don’t have to idle which can be dangerous in loud, being especially useful in bank heists with deposit boxes (e.g. RnB, RO-Bank, DB and BB). In stealth, both versions of this skill can help people not get caught and save time picking locks.
