Metroid: A New Galaxy - Boss Keys style maps

  • Being inspired by Gamemaker's Toolkit's first season of its mini-series Boss Keys, which is a series that looks into the design philosophies of Zelda dungeons in terms of layout, I decided to do something similarly for the Metroid series. This idea was fueled by things like item randomizer algorithms and 100%-speedruns, because I wanted to find a way to chart out the areas of Metroid in an attempt to facilitate pathing and maybe even help Metroid fangame makers to think about design and gating in their games.

    A New Galaxy was, dare I say, fun. It had an interesting progression system made up of two parts: collecting powerups to be able to explore places, and defeating Metroids to unlock new planets to explore. My second 100% run on Easy was about 3 hours, but I'm certain that time can be improved!
    The game can be found here.

  • Galaxy Map

  • SRX88

  • Trozodia

  • Pyrfair

    And yes, you have to go into the hot areas to find the Varia Suit. Thankfully, you can have enough Energy Tanks by this point to explore the hot zones safely for a bit, enough to find where you're supposed to get the Varia Suit. This is actual training / foreshadowing for another hellrun in the future.

  • Aqastar

    I've noticed that a lot of the game's design deals with funneling the player towards the required upgrades, by using pitfalls and hazards that can't be traversed back without that upgrade. Sometimes Save Rooms will be placed in those locations, which can force the player to progress in order to return, sometimes temporarily blocking them from going back to nab expansions or Energy Tanks until they can get past a boss. From what I can tell, every boss CAN be beaten without getting hit, and CAN be farmed for Missiles should you run out.

    Also: ooo, new item!

  • Arcteria

    During the escape sequence, it IS possible to get all of the items, upgrades, and Metroid encounters in the escape path with the sole exception of the one Missile Tank blocked by Power Bomb blocks. If any are missed, it'll be a while before the player can get back here to nab them. Including that Plasma Beam.

  • Noctian, Zero Suit sequence

    Much like in Zero Mission, there's a ZSS section. Unlike ZSS, you could run into Metroids you can't damage (and you'll just have to leave them for later). You can also find your ship, but you'll get a little cutscene saying you need at least 35 Metroids killed and your Suit restored, before you can fly it again.

  • Phazon Dimension, Zero Suit sequence

    Well this is a surprise!
    The Black Zero Suit is actually required. Collecting it will unlock a Save Station later on that will restore all your energy, which is the only way you can survive in this "dark world". You'll see a couple of other Metroids, but you still don't have your suit just yet, so you can't even scratch them. To paraphrase AI Adam, "If you see [them], just run."
    The sequence ends once you've restored your suit in the dark version of Trozodia.

  • Phazon Dimension, part 1

    As soon as you get your Suit, you'll find a portal leading back to the "normal dimension", but you'll not be able to open the doors without Power Bombs. Furthermore, you'll still take damage in the Phazon Dimension. At this point though, you have a number of options available for you to explore, and different directions you can go. And plenty of Metroids to kill.
    I love that feeling of "Okay, you have all your stuff back, and you've uncovered how this game works. Now the rest is open to you. Have fun!" in games. Even if the first half of the game so far has been fairly linear, that open feeling feels earned.

  • Phazon Dimension, part 2

    The only way to access SRX88's Phazon Dimension counterpart, is to restore access to your ship and fly to SRX88, then finding a portal there.

  • Noctian

  • Final areas

    The escape through Phazon SRX88 will have a number of areas blocked off.

  • Here's a condensed version of the above charts, showing what the whole of the game looks like in terms of item dependencies:
