Scanning Systems & Anomalies

Navigating the galaxy in Mass Effect 3 involves more than just plot progression; it requires diligent exploration of star systems. The galaxy map is your primary tool for this, and understanding how to utilize its scanning functions is key to uncovering vital resources, side missions, and anomalies. By employing various filters and paying attention to system alerts, you can efficiently gather the intelligence needed to bolster your War Assets and uncover hidden lore.

The galaxy map features a scanning mechanic that allows you to probe star systems for resources and points of interest. When you enter a system, you'll typically see a reticle that you can move around the system's celestial bodies. Firing your ship's cannons at these bodies will initiate a scan. The type of scan and what it reveals depends on the filters you have active and the nature of the celestial body itself.

Utilizing Scan Filters

Several filters can be activated to refine your scanning efforts:

Rachni Activity Filter: Helps locate systems with Rachni presence, often tied to specific side missions.
Creature Sightings Filter: Highlights systems where unusual or dangerous creatures have been detected.
Locations With Element Zero Filter: Essential for finding deposits of Element Zero (eezo), a crucial resource for ship upgrades and certain research projects.

These filters are typically acquired by interacting with specific terminals or data logs during missions, as seen in the example of finding Rachni ship data or examining large rocks for Element Zero deposits.

Scanning for Resources and Anomalies

When scanning a planet or object, you'll often see a proximity indicator. If you're too far, the scan won't register. You need to get closer to the target. A successful scan will yield resources, which can include:

Element Zero: Used for research and upgrades.
Valuable Data: Can contribute to War Assets or unlock new codex entries.
Anomalies: These are often subtle deviations in the scan results that can lead to hidden quests, unique items, or even trigger encounters.

Pay close attention to the scanner's feedback. A distinct ping or visual cue usually indicates a successful find. Sometimes, you'll need to perform multiple scans of the same area or approach from different angles to uncover everything.

Efficient Scanning Strategies

To maximize your efficiency:

Activate all relevant filters before entering a system.
Scan celestial bodies systematically. Start with planets and moons, then move to asteroid fields and other points of interest.
Listen for audio cues. The scanner often provides auditory feedback for successful scans.
Look for visual anomalies. Sometimes, a faint glow or unusual texture on a planet's surface can indicate a hidden item.
Don't be afraid to experiment. If a standard scan isn't yielding results, try moving closer or scanning from a different position.

By mastering the scanning mechanics, you'll not only gather essential resources but also uncover the many secrets and side stories that Mass Effect 3 has to offer, further strengthening your fight against the Reapers.
