# Metroid: Zero Mission

Metroid: Zero Mission is an action-adventure game developed and published by Nintendo for the Game Boy Advance on February 9, 2004. It is a remake of the original Metroid (1986), and retells the story with updated visuals and gameplay.
Like other Metroid games, the player controls the bounty hunter Samus Aran. Samus travels to the planet Zebes after learning that the Space Pirates are experimenting with Metroids, hostile parasitic creatures, which they plan to use to take over the universe. The gameplay focuses on exploration, with the player searching for power-ups to reach previously inaccessible areas. The remake adds items, additional areas, mini-bosses, difficulty levels and a rewritten story that explores Samus's past.
Zero Mission received praise for its new content, graphics, gameplay and improvements over the original, but criticism for its short length. Its honors included a 46th-place ranking in a list of the Top 200 Games compiled by Nintendo Power. It was named the ninth-best Game Boy Advance game by IGN.
Zero Mission had sold over 439,000 units in the United States and 69,000 in Japan as of February 2005. It was rereleased on the Virtual Console service for Wii U and the Nintendo Switch Online + Expansion Pack service for Nintendo Switch.

## Gameplay

Metroid: Zero Mission takes place on Planet Zebes, a large, open-ended world with areas connected by doors and elevators. The player controls Samus Aran as she travels through the planet's caverns and environments, hunting Space Pirates. Along the way, the player collects power-ups that enhance Samus's armor and weaponry, as well as grant her special abilities. These abilities allow Samus to access previously inaccessible areas, so that the game can be played linearly or non-linearly. For example, the player may come across caverns that bypass certain sections, a method termed sequence breaking. To save their progress, players can enter either Save Rooms or Samus's ship on Crateria. As a remake of Metroid, Metroid: Zero Mission's layout bears a resemblance to the original, and various powerups and items make reappearances from previous games in the series, with similar uses, effects, and appearances, but it adds items, areas, and mini-bosses, as well as a new area named Chozodia.
Zero Mission is the first game in the Metroid series to include a sequence in which the player controls Samus without her Power Suit. In this sequence, Samus is more vulnerable to damage, must crawl through ducts on her hands and knees without the help of her Morph Ball mode, and has a weak pistol that briefly stuns enemies as her only weapon. Samus retains all energy tanks she acquired previously.
Completing the game unlocks an emulated version of the original Metroid. Zero Mission allows players to unlock the Metroid Fusion picture gallery by linking between Zero Mission and Fusion cartridges via the Game Boy Advance Game Link Cable.

vte :
Space Pirates attack a Galactic Federation-owned space research vessel and seize samples of Metroid creatures. Dangerous floating organisms, Metroids can latch on to any organism and drain its life energy to kill it. The Space Pirates plan to replicate Metroids by exposing them to beta rays and use the Metroids as biological weapons to destroy all living beings that oppose them. While searching for the stolen Metroids, the Galactic Federation locates the Space Pirates' base of operations on the planet Zebes. The Federation assaults the planet, but the Pirates resist, forcing the Federation to retreat. As a last resort, the Federation decides to send a lone bounty hunter to penetrate the Pirates' base and destroy Mother Brain, the mechanical life-form that controls the Space Pirates' fortress and its defenses. Considered the greatest of all bounty hunters, Samus Aran is chosen for the mission.
Samus lands on the surface of Zebes and explores the planet, traveling through the planet's caverns. She comes across Kraid, an ally of the Space Pirates, and Ridley, the Space Pirates' commander, and defeats them both. Samus finds and destroys Mother Brain. While Samus leaves the planet in her ship, it is attacked by Space Pirates, causing it to crash back onto Zebes, near the Space Pirate Mothership. With both her ship and Power Suit destroyed, Samus infiltrates the Mothership, leading her to Chozodia, where a Chozo Statue offers her a trial. Upon passing the trial, Samus is rewarded with a new fully upgraded Power Suit. Continuing to explore the Mothership, Samus reaches the Mecha Ridley, a robot built in the likeness of Ridley. After defeating it, Samus escapes the planet using one of the Space Pirate's shuttles, while the Mothership self-destructs.

## Development

Metroid: Zero Mission was directed by Yoshio Sakamoto, a Nintendo veteran who has been involved with the Metroid series since its debut with the Nintendo Entertainment System game, and has played a role in every game in the series except for Metroid II: Return of Samus. Sakamoto was the only member of the original Metroid development team to work on Zero Mission.
While working on the concept for the next Metroid game after Metroid Fusion was released in 2002, one of the developers for Fusion suggested that Super Metroid be ported to the Game Boy Advance, but Sakamoto decided to port the original Metroid instead. The development team decided to return to the roots of Metroid gameplay by creating a game based on the NES original. Sakamoto, noting that Fusion's gameplay and structure were drastically different from previous games, wanted to "show people who had never played a Metroid game prior to Fusion, the roots of the Metroid franchise, that this is what Metroid is, this is the style of gameplay that Metroid sprang from [...] at the same time, retell the story of Samus's original mission".
One of the biggest challenges that the developers faced was adding enough elements to Zero Mission to make it feel new, while keeping the spirit of the original Metroid. Because both games were made for the Game Boy Advance, Zero Mission uses a rebuilt version of the game engine used for Fusion so that it did not need to be built from scratch. This marked the first time two Metroid installments have been released for the same video game console. Metroid Fusion had offered connectivity with Metroid Prime on the GameCube, and Zero Mission was planned to offer similar functionality with Metroid Prime 2: Echoes, but these plans ultimately fell through. Sakamoto explained that because there was not enough development time for Zero Mission, compounded by the fact that both of their release dates were too far apart, the team was prevented from doing so. They did, however, manage to include the ability for Fusion to connect with Zero Mission.
In addition to retelling the plot from Metroid, Zero Mission introduces cinematics to push the story forward. Sakamoto believed in the importance of having a story to complement a game. He found it particularly difficult to convey the plot in a way that the player can understand, because of the sparse use of dialogue in the Metroid series. The story for Metroid: Zero Mission was rewritten to explore Samus Aran's backstory more than in the original Metroid. Cinematics are used to show Samus' memories to move the story forward and to keep the plot open for interpretation. Sakamoto said this was intended to expand the original story while retaining some mystery. The game is the first in the series to let the player choose a difficulty level at the start; each of three levels varies in the amount of damage caused by enemies with the third option only unlocked after finishing the campaign once. The battle with Mother Brain marked the end of the original Metroid, but Zero Mission offers an extra story segment featuring Samus in her blue Zero Suit.
