All manner of weaponry and suit upgrades await Samus, strewn across five huge worlds. This time she'll have the Morph Ball, Morph Ball Bomb, Spring Ball and Space Jump Boots right from the start, so expect to see new upgrades to feature among her classic abilities.
Thanks to the Wii Remote and Nunchuck's motion-sensing capabilites, some upgrades such as the Grapple Beam will see plenty more action and utilisation. Be sure to check your inventory screen upon scoring any new item to read about its maximum potential.
With Samus' eventual Phazon corruption and the rollout of her new PED Suit, plenty of Phazon-powered Hypermode weaponry awaits her. All making use of her standard attack forms, few in battle can match the devastation from the very substance the Federation is struggling against.
Use the following guides to learn where and how to find every item in the game, ranging from Samus' upgrades to Energy Cells needed to access deeper regions of the GFS Valhalla. Beware of spoilers throughout, and bear in mind that the suggested order for the retrieval of most items isn't mandatory, as there's plenty of ways to go about treasure hunting. The handy humming sound when in close proximity to an item is ever-present, so keep your ears open for the auditory clue.
Note: Every item is linked to the walkthrough and vice versa (at the point where you come across specific items), so that you can easily navigate your way back and forth.
