It can remotely disable enemy firearms without the enemy being aware that the gun they are carrying has become jammed. Once disabled, these targets are shown as blue in Detective Mode so that Batman can easily identify them. This can also be used to disable TYGER sentry guns and temporarily disable TYGER helicopter machine guns.
The Disruptor can also remotely detonate proximity mines that have been placed in the environment. If timed correctly, the concussive effect of these explosions can be used to knock enemis out. Additionally, removing mines can be used to reveal secret areas or access Riddler trophies. After two uses of the Disruptor, a recharge period is required.
