== 8. Walkthrough:

Detailed walkthrough for Metroid Prime 2: Echoes, covering all objectives, items, and scans. Follow the developer-intended route with efficient item acquisition and clear mission segments.

This guide section provides the core walkthrough for Metroid Prime 2: Echoes. It has been revised from a single, potentially confusing walkthrough to a more structured approach, incorporating elements of speedrunning efficiency while still ensuring all scans and items are collected. The walkthrough follows a routed path, meaning items are acquired when convenient within the overall progression, rather than immediately upon discovery, unless required for ammunition. This generally adheres to the developer-intended route with minor pathing adjustments for conciseness.

The walkthrough is divided into subchapters corresponding to the game's main segments, such as Temple Grounds and Agon Wastes. Each subchapter covers all primary objectives for that area, including necessary excursions to other locations if they serve the main route. Trips between areas will be marked with "Mission Outlook" prefaces detailing objectives, items, and scans.

LOG BOOK ENTRIES:
All necessary scans for Log Book completion are annotated upon first encounter. One-time scans are marked with asterisks (*), and limited-time scans with double asterisks (**). Lore Scans are numbered and annotated with their type and a tracker (e.g., "[LUMINOTH LORE: "TITLE" (01/41)]").

ITEM NUMBERING:
Key items for percentage completion (Translator Modules, Energy Tanks, Beam Ammo Expansions, Missile Expansions, Power Bomb Expansions, and Suit Items) are bracketed and capitalized, showing the current count versus the endgame total and a percentage tracker (e.g., "[ENERGY TANK (01/14) - 2%]").

The walkthrough begins after Samus arrives on Aether and experiences her ship's crash landing.
