A guide to scan 100% of the systems in Mass Effect 3. Find all the objects and resources in the systems to get ready for the war and complete all the missions you get on the Citadel.
Mass Effect 3: Planets Scanning Guide
The Reapers are enemies. During our journey to save the galaxy, avoiding encounters is preferable. This guide provides information on how to locate points of interest within star systems without alerting them through scans.
Locating these points of interest will yield war assets and allow for the completion of missions given by individuals on the Citadel. Completing every system to 100% is also a goal for those who seek full completion.
Some star clusters and systems become accessible later in the game. Do not be concerned if certain locations are initially unavailable.
