METAL SLUGOPEDIA

Version 4.7

A fan-made encyclopedia based on the Metal Slug universe - and beyond

By: Soldier of the Future


What you are about to see is the product of a mind that clearly had too much time to waste. An overly long and detailed story about an arcade game with little to no lore about it outside of the most obscure locations on the internet, and you want to learn more? You've come to the right place.

Metal Slug has always been a game that has kept itself in a special place within my heart and memories, but alas, the fact it is rather underrated and somewhat dead has kept it from being prominent in the general arena of video gaming. While I've done a small number of fics based on the games (along with some fanmade content, including a partial collaboration story with a friend of mines on this site) the larger ones died off, mainly because I didn't have enough inspiration, excitement, and the necessary writing skills to continue what I started. Shame, too...as I had a lot planned for the stories. The primary stories I had planned (Guerrilla Wars and Apocalypse Sky) along with a close friend may have been discontinued, but I haven't forgotten about them. Still, I felt a great amount of debt owed for the discontinuation of those stories (six years after they took off and the characters for those pieces and they're still fresh on my mind, with vast improvements storming in my head), and I had to make up for those lost stories somehow.

This is how I'll make up for my dead Metal Slug works that have been confirmed as KIA since 2012: an in-depth encyclopedia of all the content, knowledge, and trivia that you'll need to learn before you set off as a one-man/woman army against entire legions of the Rebellion Army, Amadeus Syndicate, Ptolemaic Army, Future Rebels, Mars People, you name it... and more.

The beauty of the Metal Slug games is that there is very little actual lore - if any to begin with - provided by the creators of the games. If I recall, the only storyline that was offered was via the brief introductions that they'd provide in the manuals for the home console versions - and the majority of these games never saw an international release outside of Asia, so your best source for an actual backstory were from fan sites that would be generous enough to provide a translation. Heck, even the settings for the games and their levels were shrouded in ambiguity so it was basically impossible to tell where you were really fighting the Rebellion Army in the world. In the arcade, the whole premise could be boiled down to this: throw in a quarter, watch a quick tutorial, and blast away until either you or the arcade cabinet's buttons give in. This meant that it was usually up to the players themselves to make their own story as they shot their way through the rebel-infested levels with their trusty heavy machine guns and rocket launchers while trying to stay alive on this perilous journey. The possibilities were definitely limitless. And let's not forget the replayability level of each installment - even after beating one of the games for the first time, there was always a high score to triumph, one more prisoner to rescue, and one more enemy that survived your initial rampage!

This will be my personal contribution and gift to the Metal Slug Fanfiction Archive, as there are no dedicated and long-term projects that have been submitted to it (as far as I can tell). I'll do my best to include secret areas in the lore too. But there are some that are just hard to remember; the ones from Metal Slug 7/XX, in particular, are notoriously difficult to find and recall at the same time.

If you're reading this MegaAuthor, I tip my hat to you. You've supported me throughout my Metal Slug fics for the last seven years, so you get a special mention for the creation of this pseudo-encyclopedia. However, I must apologize for throwing his reviews out of sync with the chapters in this story ever since some chapters had to be divided into two parts (and possibly even more in the future depending on how things turn out) thus shifting a reviewed chapter into another section, but the review itself stays in the same category.

As a result, fanmade lore (customized characters, vehicles, weaponry, enemies, missions, etc.) will make appearances here too, but they will not detract the primary story itself - their purpose will be to reinforce this story with more content, and it's very likely that SNK developed the games with this in mind: let our imaginations and minds exercise themselves. I'm sure we all invented our own content at some point of time with our imaginations, one way or another.

This project initially started out as nothing more than a general overview of the main Metal Slug games, as my original plan was to end it after the chapter 'Hazards of the Battlefield'. I honestly did not believe that it would get this far - at most, I expected it to be nothing more than a simplified strategy guide with a bare-bones rundown of what you should expect from a typical playthrough. But as the months passed, it has transformed into a fairly large-sized encyclopedia jam-packed with loads of chapters worth of content that'll surely make your heart race as you read through them.

So are you ready to roll out for one big slaughter fest? Lock and load, and may Marco Rossi, Tarma Roving, Eri Kasamoto, Fiolina Germi, and a whole new cast of combatants guide you in your eternal battle against the tyranny of General Donald Morden and his fanatical subordinates on every front in a series of neverending battles and conflicts.

Do note that this encyclopedia will be continuously revised, as I reread this myself and add any tidbits or correct any errors that I might have overlooked. As time goes on, I will consider adding more content, such as the Classified Missions and Documents subsections (for one thing, I have established enough classified missions to equal the amount of Metal Slug games released to date, and that number will be surpassed very soon!). I will update this periodically from time to time if I have something new; but if I spot a mistake or you happen to catch a glimpse of one, expect it to be corrected within a personal message's notice.

Since I work longer hours now (up to eleven per day) and have other responsibilities in life to attend to, my attention on this story will be greatly decreased from now on. I will still put my efforts in terms of improving it with each passing month should I find the energy and time to do so.

I have been receiving plenty of complaints in regards to the timeline. Unless SNK Playmore officially releases a rundown of it, I will not change it (the wiki does not count as an official source). The only official source I have is the Metal Slug Anthology manual for the PSP, and nowhere does it say that Metal Slug 6 takes place after Metal Slug 3, Metal Slug 4 takes place after 6, and so on. From now on, I will no longer reply to any reviews/messages that question this. It's like the Legend of Zelda timeline: there is no direct and surefire answer. For those who want to know how much I care about this, the author that helped me with this has declared Metal Slug 5 to be nonexistent in his own universe.

Metal Slug has never placed great emphasis on a timeline, and I don't either. Don't like it? Don't complain. Write a letter to SNK Playmore, make your own encyclopedia, or throw your computer out the window in frustration. Pleasing everyone is impossible, and I certainly won't do so just because of someone isn't happy with something trivial.

Now that's over with, enjoy this database! I had a real blast making this (even more so when this project of mine actually ended up as a complete, finished, and polished product in contrast to my other long-term fic projects), and I hope you'll feel the same way reading it.

Version changes - there's just too many to name as I've constantly updated this over its lifetime (detailing every one of them would be impossible, as changes could be as minor as fixing a simple grammatical error or something as big as adding an entire chapter's worth of content), but here's a rough outline.

So what's included in this encyclopedia? Here's a basic rundown of all the chapters.

Introduction - You are here (duh). Be sure to check here for the latest lowdown on new updates, as they will be posted here first.

Metal Slug: Story and Levels - The game that started it all. Bring a halt to the madman known as General Donald Morden and his demented fantasy for the establishment of a new world order.

Metal Slug 2/X: Story and Levels - Fight the Rebellion Army and their mysteriously newfound allies that have rearmed them for another war. It appears that humankind is not alone in the universe after all...

Metal Slug 3: Story and Levels - Deliver the finishing blows to what remained of the Rebellion Army since the second war, but what about those new allies of theirs from the last war? The answers must be sought out.

Metal Slug 4: Story and Levels - Impede a potential holocaust caused by the devastating White Baby Plague computer virus, manufactured by a self-proclaimed genius only known as Amadeus.

Metal Slug 5: Story and Levels - Stop the enigmatic Ptolemaic Army and their plans to pilfer our SV-001 tanks.

Metal Slug 6: Story and Levels - Thought the Martians were the only sources of intelligent (and hostile) life beyond our atmosphere? Think again.

Metal Slug 7/XX: Story and Levels - An omen from the future is buried in the scraps of an offshore dump site.

Friends, Foes, and Factions (canon and customs included, two parts) - In-depth character biographies and organization guides are all here.

Weapons, Vehicles, and Equipment (both canon and custom content included, two parts) - Your ultimate handbook to the Regular Army's (and their allies) devastating arsenal of machine guns, rocket launchers, tanks, armored mechs, and much more.

Enemies (both canon and custom content included, three parts) - All the informative details that you will need to know for the adversaries, ranging from the basic Rebellion grunt to the fearsome Future Rebellion Army Tesla Trooper, that you'll come across on the battlefield.

Hazards of the Battlefield - From the many deaths that your soldiers might suffer to endless pits of pools and corrosive acids, they are all detailed here.

The Classified Documents and Missions - Having only been declassified and authorized for general release recently, these files contain highly clandestine information - ranging from the profiles of extremely dangerous combatants to experimental weaponry that were never meant to be fielded for a conventional military force. These chapters will also include details of military operations that were considered to be nonexistent by almost all governmental authorities, for various reasons. Whether you wish to learn about the life of Marco Rossi's loose-cannon son, experience the sheer power of the BFG9000 or the Future Tank X-3, or discover the truth behind the Demonic Forces of Hell, you will find it all from within this category. As these files are still sensitive documents in every aspect, proceed to read at your own caution. Consider these to be expansion packs to the canon games produced by SNK Playmore, as that was my original intention: to expand on the official games.

Might of the Marines - Battle the Rebellion Army's elite Paranormal Division forces with two surviving Marines as they attempt to prevent a hostile takeover of Europe and a literal Hell on Earth.

The Elimination of EXALT - Field two of the finest experimental soldiers of the UNSOC against the enigmatic EXALT while unraveling their nefarious plots against the world and its governments.

The Hunt for Rugal Bernstein - An enemy far more dangerous than General Morden has surfaced. The Ikari Warriors will be the counter. Are you prepared to lead them into the battle?

Omens of the Future War - The future is closer than you think, and even more so when the legacy of Amadeus marches on. Prepare for the ultimate battle against the perfect enemy of humankind.

Classified Weapons and Equipment (two parts) - Could not get enough satisfaction with the conventional weapons and need something more to deal that extra explosive damage? You'll find the weapons of tomorrow that will surely satiate your desire to initiate maximum carnage and destruction with the pull of a trigger right here.

Classified Vehicles (three parts) - Witness the world's greatest technological achievements of military science in the form of vehicles beyond your wildest imagination. Whether it is the nimble SV-004 Metal Slug 'Leaping Spider' Neotank or the gargantuan Mastodon Behemoth Tank, you'll find yourself a ride that you'll grow to love in this chapter. And if that wasn't enough, prepare to feel the destructive force of the most powerful arsenals in existence coming in the form of the mighty Capital Units of the Regular Army and the Steel Beasts of their adversaries!

Classified Characters (two parts) - Even though many of the older veterans have either passed on or retired from the battlefield, you're never alone in this desolate world where war has become a common everyday occurrence. Team up with (or even go against) new faces - including those that are anything but human and are gifted with terrifying new talents - as a dark future looms upon the Earth.

Classified Factions (two parts) - Humanity is constantly evolving to fight new dangers, and so do their allies and adversaries...

Classified Mission: Valkyria Chronicles - When wars can't be won the conventional way against an enemy from within, turning to unlikely allies is usually the solution.

Classified Mission: Vortexes of Time - Sometimes the only choice to alter the course of defeat is to change the path of history itself, especially when the possibility of virtual annihilation of humanity is all but a dawning prospect. But tampering with a force that was never meant to be trifled with may come with its own irreversible consequences...

Classified Mission: Demon Eclipse (four episodes divided into two parts) - The road to Hell is paved with good intentions, and the Chronosphere program is an example of this saying that will be forever engraved into humanity's bloodstained history. Travel beyond the boundaries of our universe here, to a world that was never meant to be discovered by humanity.

Classified Mission: The Paranormal Equation - An altered timeline has morphed the Rebellion Army's elite force into a superpower. Lead them on a notorious campaign against everyone who opposes them to make the Fourth Reich and an actual Hell on Earth a reality.

Classified Mission: Yuri's Revenge - The new timeline has revived some clandestine secrets of the Cold War, including a long-forgotten psychic black ops program originating from the Soviet Union...

Classified Mission: Chaos Control - The world and history as we know it has been altered and rewritten completely. Under-gunned, undermanned, and vastly outnumbered, the Regular Army Future Forces prepare for the fight of their lives against an enemy considered to be a far cry from the Rebellion Army.

Epilogue - Peace forever.
