Logic Probe

The Logic Probe is an item found in System Shock.

This handy gem was rigged up by some hobbyists in Engineering to help them bypass electronic locking circuits aboard Citadel Station. Each probe has a one-time use for solving any puzzle aboard the Station. They’re usually successful, but occasionally some probes fail if you use them on panels you have unsuccessfully attempted to unlock before.

To use the probe, select it from the "ITEM" MFD panel and drag it onto the puzzle you wish to solve on the view screen.
