Metroid

Samus took it to a galactic research station, and scientists assured her that the powers of the larva can be harnessed to help people.

However, everything goes wrong when a dragon kills the scientists, takes away the larva, and destroys the research facility.

Samus follows the dragon to the planet of Zebes, where she fought Mother Brain before.

She must explore the dangerous planet, stay alive, and figure out a way to retrieve the larva.

Super Metroid is a platform game and a follow-up to Metroid II .

Like the previous games in the series, it is not divided into separate levels; the planet Zebes is an open world which Samus traverses back and forth.

This world is divided into rooms separated by doors which must be shot to be opened.

Shooting is also used to open up secret passages, some of which contain nifty bonuses, but finding most of them is required to proceed in the game.

There are many items to find on the way, and each new item usually makes heretofore inaccessible areas available to Samus.

The items include both weaponry (such as missiles, super missiles, or upgrades to Samus's standard laser gun), energy tanks that increase Samus' max health, and other gadgets (like a grappling hook that allows Samus to stick to the ceiling).

There are various enemies - alien fauna - lurking around planet Zebes.

The enemies all respawn after re-entering a room, though Samus' increasing capabilities mean that they become easier to defeat as the player makes progress.

After killing them, the enemies typically leave behind some health or ammo.

Metroid for Game Boy Advance is currently worth €133.53 loose, €210.30 complete in box, and €641.69 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Metroid has only a handful of tracked market sales, suggesting relative scarcity compared to more common Game Boy Advance titles.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Metroid, loose is €133.53 and CIB is €210.30 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Metroid is currently worth €133.53 loose, versus €70.08 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
