This game is waaay too forgotten.  Metroid:  Zero Mission was released in 2004 for the GameBoy Advance.  This game is very similar to previous 2D Metroid games.  The game was made by Nintendo’s Research and Development Team 1, and is highly acclaimed.

Possible Spoilers Ahead (unlikely)

Metroid Zero Mission is the first game in the Metroid timeline.  It’s called Samus’s “zero mission” for a reason.  She travels to Zebes to destroy the Space Pirates’ attempt to use biological warfare in the form of Metroids, a sort of parasite that sucks life force out of victims.  So she destroys the attempt, but then gets shot down as she escapes, and has to find another Power Suit in the ruins of Chozodia, a place formerly inhabited by the Chozo, a group of bird-like people that raised Samus.  Samus was also revealed in the game to have been raised there.  She destroys the mothership of the Pirates, and leaves.  She also destroyed the leadership of the Pirates.

So the game has an interesting story, and has the first appearance of the Zero Suit.  It has the power suit, the varia suit, the zero suit, and the gravity suit.  It also has a lot of abilities that are seen throughout the series.  This game is very much the standard Metroid.  It has all the elements of a “Metroid game”.

Overall, the game is really good, and I want to play it again.  I give it a 9.5/10.  I don’t know of any other platforms you can play it on, but I’ll be sure to find out soon.  Until next time, have a great day.
