Metroid: Operation Execution is yet another hack from Roebloz, this time tackling the challenge of making a good Metroid Zero Mission ROM Hack.

It follows the story of Samus (Yet again) going to investigate and shut down the Space Pirate operations on Planet Triea 31 shortly after the events of Metroid Zero Mission, and avoid the Space Pirate elite known as the Executer. (The story is explained more in-detail inside the README file.)

The hack redesigns the whole map and alters the enemies a bit, making it a brand new adventure. The graphics have remained mostly the same, with some additions for areas such as Kraid’s Lair featuring graphics ported over from Super Metroid, and the Spikes from said game having been ported over as well. There isn’t any ASM work either, so this is a nice vanilla hack for those who prefer simple hacks.

Got boredom to kill? Then get your Charge Beam ready, and get ready for your new mission; Execute…Or be executed.

DIFFICULTY: Journalist Friendly/Challenging/VERY Challenging (Depending on which difficulty you choose in-game, of course.)

Read the Readme for more information on the hack.

Hotfix Update: Fixed game-breaking bug.

Having a billion enemies in every single room was interesting to say the least, I didn't really love it but there were some enjoyable parts. The chases and the escape sequence were pretty cool. 3.5/5

The level Design is pretty nice. What I don't like is the number and placement of the creatures.

For reference, I'm not a speedrunner or anything, but I have done minimalist runs of the prime series and Samus Returns, and Dread Mode on Dread. Completion time is the last save before Ridley, whom I was unable to beat even in slow motion 15fps. I enjoyed this hack for a while, but then it just got ridiculously hard, completely dwarfing the vanilla game. I played on normal mode. For me, it was not enjoyable without save states, slow motion, and rewinding. This is because the number of enemies is ludicrous, there is one (and possibly more than one) deathtrap, and the placement of enemies and obstacles seems to almost be made precisely to get in your way and surprise you. It seemed like a series of enemy gauntlets to each upgrade which you had to backtrack through after obtaining. I did like the earlier chases, though they seemed a bit short, but the one leading to Ridley's lair is insane and from watching the rest on youtube, it seems like it doesn't get any easier. I would say it's worth a play if all this doesn't deter you.

What can I say about this hack...
A nightmare.
Not cause of the difficulty. I get it. Hard sponge enemies (including the farming enemies. and guess what? you NEED them. HARD. SUPER HARD. if you want to survive. you need to farm. HARD.)
then you get to the possibility to get early super. you get it and bam you hardlock yourself in the ruins by entering them before you should. no way back.
ok you EDIT the doors to get back and continue. then you get back there you do a very very hard excape from the executioner, and you skip all expansions cause you're followed by him. Ok I'll get them later.
You go back at the end of the game. Guess what? the door to the excape with executioner is locked so all those items are unobtainable. Door editing again.
You enter the final area (the labs) and go beat it with thousand savestates cause the amps hit you hard as a truck. then the metroids which require 3 supers to kill (with no refills besides puny -ZM rng- cheerios) and you basicly need 100% (which is 93% btw) to even get through + refilling slowly.
Then you try excaping and good lord mother brain was hard but a nice welcome fight (though in my case it was harder cause i had to go back and edit a door to get through back to the invincible enemy to get the missile and didn't heal in any way).
A mess but a good direction in hacking. thanks.
(sorry for all the edited doors but the road blocks :( )

I enjoyed this hack but I hate how buffed Ridley was. tbh he's the only thing that's keeping me from giving this hack a full 5 orbs.. like goddamn why he gotta have so much fuckin health?? I mean I beat him, using cheat codes cause he's too damn difficult without it, and that's one problem I have with this have to fight Ridley to get a certain item to get wave and I hate that he's blocking the only item that'll get you to wave like maybe if he was guarding ice beam instead then beating him would be so much more doable since he's so damn difficult when you do come across him

Apart from that bs,I enjoyed the hack and it's interesting and unique level design and how all the space pirates were removed and replaced by a single space pirate that was buffed and acted sort of like the SA-X from Fusion (the SA-X appears in multiple places that you go to and even tries to hinder you by killing you on sight when it spots you)

I probably won't be playing this hack again due to the fact that I had to restart FOUR fuckin times due to the fact that I kept missing items and I FINALLY got all of them (like the person above me has stated, max item percentage is 93%) I really want to recommend this but I don't think I can, all I will say is play at your own risk and be careful when fighting Ridley, he's not like vanilla ZM Ridley so don't go easy on him..

WARNING: NOT VANILLA DIFFICULTY. Much closer to Veteran. There are many points of contention for tedium in this hack: there are so many enemies that take way too many beam shots to kill, and a mandate of two platform crawling enemies plus one floater/Ripper has been placed on every platform in every room in the game. No joke. You will end up breathing a sigh of relief every time you get that one upgrade that makes enemies die 10% quicker, only to be faced with a new area and another truckload of enemies. You will be scrounging through enemies for health, and you will be clinging to save points as mediums of survival - not unlike Dark Souls. It is not unfair, it is totally beatable, but my enjoyment was definitely middling every time I encountered the low health alarm. Ridley was definitely tough, but the massive buff he received taught me his tail pattern so it wasn't all bad. If anything the best part of the hack is the bootleg SA-X - I mean the Executioner. Any time he's on screen, you need to scoot, and that includes the final encounter. (You don't need to kill him - he can be cheesed by platforming at the top of the screen until his AI decides he can't find you, then you sneak through the gate before he does find you.) The worst part is that stupid kill pit right in the middle of Brinstar that serves no purpose other than to frustrate you for falling in at any time, as there is no escape. It doesn't belong in a Metroid game. It ruins my map%.
