Metroid Prime/Walkthrough

This walkthrough for Metroid Prime is split up in a logical progression to achieve a 100% completion in a reasonable amount of time and with manageable difficulty. For the most part the equipment upgrades must be collected in a certain order, so the game is fairly linear in that sense. There are, however, many secondary items (Energy Tanks and Missile Expansions) that are optional, though there are several bosses that will be difficult to defeat if you don't take the time to collect them when you can.

In addition to collecting all the items to be found, this guide will cover the log book entries that can be collected in the game. These are optional, but bonus materials become available when collection milestones are achieved. Many of these entries are "Missable", meaning they can no longer be collected after you reach a certain point in the game. In some cases the window of opportunity is very short, for example a single boss battle. This guide will warn you in these cases so you can be sure to collect the entries before it's too late.

Each article is named after a major area to be explored or item that must be acquired. Back tracking through areas is common.

Setting and backstory

Most of the game takes place on the planet Tallon IV, home of the Chozo civilization. The Chozo achieved such a high degree of advancement that they left their corporeal bodies behind to explore higher planes of existence. This changed though when a huge asteroid fell on Tallon IV, burying within it an evil force which began to poison the planet. The Chozo tried to contain the evil, but they too were poisoned so all that remains of their civilization are decaying ruins.

Meanwhile, the Space Pirates, a warlike race dedicated to conquering the galaxy at any cost, discovered the asteroid and began to extract the deadly substance Phazon for their own use. They set out to destroy the remnants of the Chozo civilization and unseal the evil buried within Tallon IV.

Tallon IV is divided into six areas, each with its own character, and each area is subdivided into many rooms which show up as separate units on maps. The space frigate where the game starts can be considered a seventh area.
