Yesterday evening I played the built-in AM2R randomizer (maximum randomization level) up to the point where I got all the important items and the rest of the game would be a victory lap mopping up Metroids. Took about 5 hours, not bad for my first randomizer experience.
Before getting any non-missile items I went all the way down to the lowest area (where every enemy could two-shot me) in search of any passable entry point, then concluded it was impossible to my knowledge so I looked at the .txt manual for what I might be missing. It duly explained “walljumps or bombjumps are required on most seeds”. Ohhh right walljumps, that thing I never do because I’m so bad at it.
Then I walljumped my way to the right of the golden temple and was able to pillage the place from there, finding a bonanza of supers and power bombs (which I suspect might mean this was an easy seed, but I lack a sense of what’s common). Then I used the power bombs to explore a lot of bomb-blocked areas, which is an interesting randomizer-specific challenge because it means you have an exploration budget before you need to go back to the save point or farm enemies (and I did softlock my run twice by miscalculating).
In Hydrostation I found the spacejump in this spot:
After taking that photo as a reminder, there was nothing stopping me from going on the right side and using powerbombs to get to it, but then I realized that it was impossible to walljump or speedboost up there. This is a randomizer-specific conundrum because in vanilla, if you arrived there in late-game you would simply spiderball or powerbomb then highjump, and if you arrived in early game you could get it with bombjumping with a little more effort (bombjumping is easy in AM2R). After seeing Space Jump in this photo it was another 2 or 3 hours before I could get it.
Hydrostation also had Screw Attack (ceiling secret) and Speedbooster (the boss’s item) so it was a real item bonanza (again, easy seed?), and those two I was able to get without further dependencies. I was excited to get early screw attack thanks to access to the teleport pipes, but in the end they didn’t let me access anything important I couldn’t have reached by walking anyway.
There weren’t really any important items in the accessible parts of distribution station and the industrial zone, so the final key part of my randomizer run was in the Tower. Now like I said I never did much walljumping before and the Tower seemed potentially very demanding on the walljump front, so I was hoping this seed would give me any of one of the 3 spacejump-unlocking items somewhere else so I wouldn’t have to. But after poring over the map (comparing it to an online map with all item locations) and exhausting every other avenue of progress, there I ended up facing the steep wall of the tower.
Before trying to reach the top I realized I could check (without picking up) the 2 items inside the tower to determine if one of them was bombs/highjump/spiderball, in which case I would fight the boss, otherwise not bother to challenge it. I “only” needed to walljump about 5 screens high to reach the morphball crack on the left side of the tower. My first check (powerbombing to reveal the item I can’t actually reach without beating the boss) didn’t show bombs/highjump/spiderball but it did show me this:
Well, it’s not what I was looking for but it’s another mandatory item, so after going back to pick up known supers/E-tank locations plus charge beam and gravity suit (I had lost them by dying/softlocking) I challenged the tower boss. It was a huge pain in the butt to fight it without space jump nor spazer, but gravity suit and screw attack also made it basically impossible for it to kill me either, so I eventually won the battle of attrition.
After getting ice beam and exiting the tower on the right, one big advantage that I hadn’t even thought about is that I was now about 2/3rds of the way up the tower, having gained some height indoors, plus I was now on the right side with more grip locations. From there I climbed finally up to the top of the tower (something I had tried to do from the bottom a couple of times, but kept losing my rhythm, then seeing my skills degenerate further due to thumb fatigue). Then there it was plainly visible in the top-of-tower-E-tank location, those purple bombs that I always took for granted before trying a randomizer.
I quickly did the morphball maze to grab them, went back for spacejump and finally reached what I recall twitch randomizer speedrunners call “go mode” (which for me is actually “stop-playing mode” because I don’t see the point of backtracking everywhere to kill 25 Metroids with overpowered late-game equipment, seems a bit dull if you aren’t speedrunning).
