Mass Effect System Guide

The Mass Effect System Guide is a key to all the systems found in Mass Effect, and offers a quick glance at the relevant game information. Here you'll find which cluster a system is in, how to unlock it, and the links to the missions and assignments contained within it. Extra detail is provided for long collection assignments to help you find exactly the piece you're looking for on top of the other assignments in the system.

The systems themselves are broken up into those parts completed by scanning from your ship and the parts completed by landing on or docking with the a planet, moon, or ship in the system. Each system also contains direct links to the main system page as well as the landable object within it, in case you would like more detailed information.
