Planet Scanning

Scanning is a new system in Mass Effect 2 that replaces the searching for minerals in the Mako approach of the first. Scanning occurs upon entering the orbit of any side planet, at which point you'll be prompted to start the scan. Once begun the planet will be overlaid with a rectangular grid. You may then press and hold another button to begin a mineral scanner which is slower than the main scanner unless you've uprgaded it on the Normandy. A data column will appear on the side of the screen and you then move the scanner around until you find large deposits of minerals. You may then fire a probe at the deposit and add to your stores.
