The Power Signature scan is a support power that was developed by the Black Hand following the Firestorm Crisis. Deployed from the Operations Center, it can detect all Power Plants, whether friendly or enemy, across the battlefield.
Role in the campaign
As GDI Power Plants are usually placed within their bases, discovering the location of enemy power plants often results in the discovery of large portions of GDI bases. The AI LEGION used this ability several times during Kane's return to power and beyond when granted control of Black Hand forces.
The Power Signature Scan is exclusively available to the Black Hand subfaction of Nod, except in a few missions of the Campaign.
