Mass Effect 3: Galaxy - Basic information Mass Effect 3 guide, walkthrough

Last update: 30 October 2022

This page of our game guide contains the most important information about traveling through the galaxy in Mass Effect 3, including how to deal with the Reaper assaults problem and how to scan planets or moons.

Galaxy exploration in Mass Effect 3 looks little different than in previous parts. The basic difficulty is a fact, that during searching the astral constellation which are attacked or seized by the Reapers, you can be detected by them.

Reapers watchfulness increase with each scan of the vicinity you do which is seen as a fulfilling the bar in the left bottom corner of the screen. When it's full, flying Reapers units appear which force you to leave the constellation by using the Mass Relay or flying to the edge of a system (better option). In the second case there is nothing against moving back immediately to this system. Watchfulness bar doesn't reset at once, so this trick's aim is to provide us few additional seconds before Reapers arrive.

The second important change in relation to Mass Effect 2 is a fact, that game doesn't let you scan every single planet and moon but only locations that were shown as an interactive during the scan (screen above).

After marking an interactive location you have to fly there immediately. Depending from the type of this object/location, you can get some resources at once (wreck) or only after exact scan of the planet/moon, which aim is to find white point for releasing the probe.
