* Full mission & optional assignment walkthroughs * Massive galactic codex section for all the background you could want * All Achievements and how to get them * Mass Effect warfare secrets revealed
This book was just a mess. There were references to whole sections that didn't make the final cut. There was no index. I hate to advocate using an online resource over an official guide, but the Mass Effect wiki will serve you better than this book can.
This guide didn't tell me much I didn't already know, but it'll serve me well if I ever write a Mass Effect-themed D&D campaign. I wish the guide had the full codex to read.
