Full Walkthrough Roadmap
This section of IGN's Mass Effect 2 wiki guide details the Full Walkthrough Roadmap, which will help you complete each and every Mission in the game for a 100% run. The IGN Walkthrough for Mass Effect 2 provides individual sections for the main Mission Walkthrough, Side Quests, and DLC, giving guides, tips and advice for players tackling them at any point in the game.
However, we have also accommodated for players who want to have a step-by-step walkthrough of the entire game for a perfect 100% run. To do this we have included a box at the bottom of every page telling you what you should do next. Several factors were used to determine the order these appear in, including story context, opportunities for unique dialogue, and conserving Fuel (since Fuel costs Credits, and those are in limited supply in Mass Effect 2).
With that out of the way, here is our complete, Full Walkthrough Roadmap to 100% Mass Effect 2. Dossier, Loyalty and Mandatory Missions, as well as the major DLC, are bolded, while shopping, Firewalker and N7 Assignments are not.
Prologue
A month after the defeat of Sovereign in Mass Effect 1, Shepard and the crew of the Normandy scour the galaxy for the last remaining Geth holdouts.
