R-Type, along with Gradius, is one of the longest-running, most-heavily ported starfighter-based Shoot 'em Up series in videogame history. From its initial 1987 incarnation as R-Type in the arcades and on 8-bit computers, it was ported to the 16-bit era and forward, and eventually reached a final episode in R-Type Final for the PS2. However, Gaiden Games are still in development for the newest systems, so the series doesn't seem to actually be dead yet.The backstory, such as it is, is fairly minimal — humanity banishes a hideous bioweapon (the Bydo) into a Phantom Zone, which then goes back in time and attacks humanity several hundred years earlier. The R-Type series of fighters are developed as quickly as possible to fight back the threat, using the Force Device, a piece of Organic Technology which uses a contained larval Bydo to produce an indestructible (but not impenetrable) energy field.From a gameplay standpoint, the R-Type series is notable for requiring significantly more memorization of its maps than many of its competitors. The original game also pioneered the idea of a system of powerups, each of which did something different (three laser crystals with a corresponding weapon, bits, speed boosts and missiles); prior to this implementation, pickups were either point bonuses or all did the same thing, as with the currency-like system of Gradius.
Games in the series
open/close all folders
The first game in the series (obviously). Your ship, the R-9, could be equipped with two invincible bits that would hover above and below your ship, homing missiles, and a Force Pod. The Force Pod could then be equipped with crystals that filtered its energy to create various lasers. Yellow shot lasers almost straight up and down, and they would follow the ground, blue shot one laser forward and two lasers diagonally that bounce off surfaces and red shot a pair of lasers, one red and one blue, forward in a transverse wave formation. The bits would also fire lasers if the red weapon was used.The Force Pod itself could be detached to float on the opposite side of the screen, and called back to slowly home in on your ship and eventually attach to either the front or back of your ship, dictating where the Force Weapon was pointed.The R-9 is also the first protagonist ship to have a chargeable laser, called the Wave Cannon. Just hold down the fire button and release when the BEAM bar is full.
R-Type II (1989)
The second game. Mostly identical in gameplay to the first, but did add two new Force crystals: green and grey, which fired a semi-homing laser (nowhere near as cool as it sounds) and a straight, short-ranged shot with a wide area of effect, respectively. These did not catch on, and the green and grey power-ups were not seen for the remainder of the series (although the weapons themselves made a comeback in Final, as the standard armaments of a variant of the original ship). The Wave Cannon was powered up as well: at full power it would split into numerous smaller blasts (in Final, this was renamed the "Diffusion Wave Cannon").The game is notable for being shorter, but much, much harder than the first game, and also for being extremely difficult to find nowadays. The graphics were, furthermore, noticeably touched up from the original.
Armed Police Unit Gallop (1991)
A very obscure spinoff, know as Cosmic Cop in some territories. The gameplay is much different here, there is no Force and the main shot can't be be charged up. Instead, the ship is armed with a lock-on laser and it can be upgraded with missiles and shot powerups found in each levels.One of the unique feature of Gallop is the ability to control the scroll rate—The further to the right the ship is, the faster the screen scroll, completing the levels quickly award much more points. The very thin plot involves a peacekeeping organisation chasing Bydo-infected "mad cars".Many fans think Gallop was retconed as part of the series by Final but this isn't the case. The arcade flyer refers to the player craft as a part of the R-series, and some tracks from it were included in a music album released in 1993.
Super R-Type (1991)
One of the first generation of SNES games released, Super R-Type is a remake of R-Type II, with the added groin-kick of no checkpoints thrown in on top of that game's existing difficulty. Super R-Type also suffered in the same way Gradius III did; when there's much happening on screen, the game grinds to a halt from slowdown; the sudden returns to full speed when everything stops trying to kill you will usually sent you speeding into a wall, then send you to the start of the level, then send your controller into the TV screen.Super R-Type may have been plagued with slowdown but it introduced a number of elements that were not present in R-Type II.
R-Type Leo (1992)
Leo was a great departure from previous games: the Leo has no Force Device, opting instead for two oversized Bit Devices, and no Wave Cannon either; charging instead allows for a state where the Psy Bits become wrecking balls, speeding around the screen attacking targets. If they're not recalled before the charge runs down, the player is punished by having them take longer to recharge. Leo wasn't a popular game, to the extent that it never even received a home port.The plot centres on a planetary climate control system going haywire, and Earth's efforts to eradicate this menace before it can spread further.Leo forsakes the series' focus on checkpoints and punishing difficulty; the game continues running after losing a life and even after using a continue, and when you lose a life the ship even drops a powerup. However, the Japanese version do keep the checkpoint system of the older R-Types.
R-Type III: The Third Lightning (1993)
R-Type III was the first completely original R-Type game not released in arcades; instead, it's a SNES-only game. Irem obviously learned the lessons of their first SNES outing, since it smoothed out the slowdown issues of Super. R-Type III was the first game to introduce an element of choice to the game, with the player asked to select between a Standard Force, Shadow Force or Cyclone Force at the start, and the R-90 able to manually switch between two Wave Cannons at the press of a button. Both are among the most potent weapons in the series; the Mega Wave Cannon's beam goes straight through walls, while the Hyper Wave Cannon allows for a period of firing super-powered normal shots followed by a brief cooldown time. The loop system of Super was kept, and became the standard in all subsequent games.As usual, the plot is minimal; there's a new Bydo threat from a new master Bydo creature that may be their leader (but isn't), and you're sent to sort it out.
R-Type Delta (1998)
Made for the Playstation 1. It fixed several things from earlier games that made the gameplay much more enjoyable: first, Speed-ups were dropped completely, instead, the player can manually adjust the speed of the fighter. Second, it ditched the Hyper Wave Cannon from III and replaced it with the Dose Attack (known in later games as the Delta Weapon), which is pretty much a rechargeable Smart Bomb. Finally, it expanded on the variety offered by the three Forces in III, this time allowing three different ships to use: the R-9 Delta, which is the classic ship players knew and loved, the R-X Albatross, which had weapons that could be spread out or concentrated, depending on the situation, or the Bad Ass looking R-13 Cerberus, with powerful weapons and a Force that latched onto enemies For Massive Damage. Just for fun, the familiar POW Armor is also unlockable, and it is by no means a Joke Character...The game is also considerably darker in atmosphere than previous entries, due largely to switching the cartoony sprites to 3-D graphics that, for the first time, truly captured the dark essence of the Bydo. The music also took a turn for the eerie. All this means that a couple of the later stages can turn genuinely scary if you let yourself get drawn in. The level design is highly praised, particularly the second level, which had underwater sections in which the sound effects and music would change accordingly.While R-Type, R-Type II, and R-Type III are assumed to happen in chronological order, the events of R-Type Delta actually takes place shortly after R-Type; an entire level is dedicated to enemies from the first R-Type game (with many of them sporting considerable damage, implying that these were the same enemies the R9 first fought), and the introduction sequence just before the player is allowed to select their ship of choice clearly reads "A.D. 2164, Asia"; the events of R-Type first start in A.D. 2163, according to official materials.Again, there isn't much to the story. After the First Bydo Mission (as the events of R-Type were known in-universe) the Bydo launch another attack, managing to infect a Humongous Mecha called the Moritz-G and unleashing it on Earth. Once more, the R-series pilots are called in to defend Earth, and kill the Bydo at their source.
R-Type Final (2003)
Final, on the PlayStation 2, was intended to be the big finale to the series (as indicated by its name), and, as such, the developers went all-out in one department: the available ships. Taking the "multiple fighters" idea from Delta and running with it, there are 101 ships to unlock and use in battle, including every ship seen thus far, as well as scouts, Transforming Mecha, Living Ships, and a flying tank, along with several dozen Forces, Wave Cannons, Bits, and Missiles. Before you get too excited, keep in mind that many of these are not unique; most are simply more powerful versions of others, and many had little quirks or gimmicks that made them difficult to use effectively (such as the infamous B-3A series, also known as the "Misty Lady" series, which had weapons that only fired down. It's as annoying as it sounds). The actual gameplay is considered a step down from Delta, with stages that weren't quite as imaginative as Delta's, although the story did branch a couple of times for variety.While the individual ship descriptions offered a surprising amount of backstory, the in-game plot itself is even more minimal; no dates are given, making tracing the time passed extremely difficult; the English-language manual states that Final takes place 500 years after the first few games, while the Japanese manual states that it's only been 20 years and the entire game is implied to encompass the years in-between all the previous games. Either way, the story starts when a space station gets infected and falls to Earth. The first few missions are spent cleaning up the Bydo that survived the fall before heading out into their dimension (again) and attacking the source of all Bydo (again). This time, however, it is implied that humanity actually found the correct "source" and defeated the Bydo for good. There are Multiple Endings.
R-Type Tactics (2007)
A Genre Shift from the rest of the series, Tactics (released as R-Type Command in North America), features turn-based gameplay that still managed to remain fairly true to the series's roots as a shoot 'em up. It is a retelling of one of the Bydo Wars featured in the older games, though which one exactly is not made very clear; some fans prefer to think of it as an Alternate Continuity. It is told not from the perspective of one single fighter pilot, but from the perspective of a fleet commander, featuring the larger war effort hinted at in the earlier games. The player commands a slowly-growing fleet of various R-Type fighters (mostly taken from Final's huge motorpool) and larger warships against similar fleets of Bydo fighters and warships, as it moves from the Sol System, to the Tesseract (a sort of bridge between this dimension and the Bydo's), and finally to the Bydo home system. The game perspective is from the side, rather than top-down, retaining the feel and look of the original games, while many locales seen throughout the series return. Even gigantic versions of classic bosses Dobkeratops and Gomander make appearances. A sequel titled R-Type Tactics 2: Operation Bitter Chocolate was released in October 2009.
The sequel to R-Type Tactics, R-Type Tactics II, for the first time in R-Type history, pits humans against humans; however, gameplay is still very much the same, with a few changes from the first to make the game more balanced. The story goes as such; with the Bydo gone for a significant amount of time, the Space Corps is called upon to scrap their Force-based weaponry as those were Bydo-derived weapons (the game's advertising tagged them as the "Devil's weapon", a fitting name). However, the Space Corps ignores the calls, and the pressure builds up until a Mars-based group styling themselves the Granzera Revolution Army dedicated to forcing the Space Corps to abandon their Force weaponry rises and challenges them. The Human campaign allows players to play either as Space Corps or Granzera forces with customizable characters, mugh like the first Tactics; both armies start with different units and focus on vastly different play styles. Interaction with NPCs are possible through the player's actions, which also include such things like treating your Space Corps/Granzera prisoners well, or being generally apathic to their cause and situation. As with the first Tactics, you get to play as the Bydo as well, although this time the story gets considerably darker in tone even by the depressing standards of the first Tactics Bydo Campaign.
As well as these, there were two compilations released — R-Types for the PlayStation and R-Type DX for the Game Boy Color. Both contained versions of R-Type and R-Type II, and both were published in 1999 in the US, with earlier and later releases elsewhere. R-Type Dimensions is an Xbox LIVE Arcade port of R-Type and R-Type II with remade graphics and a few new features. The original arcade versions are also available.The Wii's Virtual Console also had the TurboGrafx-16 release of the original R-Type available beginning from December 25th, 2006, although the game was delisted on March 30th, 2012.Copying R-Type was quite the thing for a long time, to the point that Irem ended up suing Factor 5 (makers of the Star Wars: Rogue Squadron series) for producing Katakis.
Tropes originated by R-Type:
Attack Drone (While Gradius originated the "Option" drone, the idea of a Force-type drone started with R-Type)
In certain releases, they're eyeballs; in others, they're sacs of corrosive fat.
Advancing Wall of Doom: The scrolling sometimes turns entire stages into the opposite, but R-Type games have also featured various crushers, most notably in the foundry level of R-Type III, where giant metal presses would close from the top and bottom of the screen with only a few safe spots. In later games, also used as part of Timed Boss situations: Subkeratom in Delta features an invisible one that forces you to crash into the boss if you run out of time.
AFGNCAAP: Aside from a bonus CD only released in Japan and the pilot's hands being visible at the start of III, we don't even know what any of the R-series warship pilots look like, let alone who they are.
All Up To You: Averted, oddly enough—despite being the only fighter you ever see, the backstory and setup makes it very clear that you're part of a much, much larger war effort.
The other fighters are first seen in the original R-Type's ending.
They are also shown in R-Type 2, where the last boss has captured 4 other fighters. They take part in the ending, which depending on the version of the game, may involve a Heroic Sacrifice but is always a Crowning Moment of Heartwarming teamwork.
You see more pilots in action in one of the alternate endings to R-Type Final: You become corrupted by the Bydo, and make war on your former allies. The final stage is you fighting off various R-Type ships, your former allies. And the final boss for this route? The one, the only, the original R9-A Arrowhead.
And Man Grew Proud: The Bydo were created as a living weapon system by humanity in the future.
And Then John Was a Zombie: The Cerberus ending in Delta, the second ending route in Final, and the human side endings in both Tactics/Command games.
Ars Goetia: A couple of the ships in Final are named for the last two members Solomon shackled, Andromalius and Dantalion. The Dantalion lives up to its demonic namesake by being the BT-X—the first heavy-duty intentional incorporation of Bydo tissue into the ship itself, rather than just the Force.
Attack Drone: The Force Device was an independent Bydo-based device over which you had limited control, and which actually received most of your power-ups. Bit Devices fall into the same category.
Awesome but Impractical: Describes about a fifth of the fighters in Final. Giant piledriving spikes might sound good until you realise their range is about one ship length.
The fully-charged shot of the Giga Wave Cannon will, if fired from the far left side of the screen, vaporize everything in the field of play...after spending a whole minute (which, in this style of game, will feel like an eternity) charging and leaving you completely vulnerable. (Made even worse by the fact that the 2nd-loops charge is more than enough to deal with most things.)
R-101, the Grand Finale, is a fully customizable ship. You choose what Force, Wave Cannon, missiles, and Bits it uses. To get it, you have to complete the game a few times with the R-100, the Curtain Call...which has all the same perks. And to get that, you have to complete the game a few times with the R-99, the Last Dancer...which also has all these same perks. The only thing you're really getting with the R-100 and R-101 are different chassis shapes; R-99 looks like a traditional R-Fighter, R-100 looks a bit more spiky, and R-101 is just..strange.
Badass Normal: Compared to all the other Forces that the R-series fighters use, the Shadow Force does not use a Bydo embryo.
The Bad Guy Wins: The human campaign in Command, where your fleet gets Bydo-ified at the end. Then you play as the Bydo for the second half of the game.
Battleship Raid: You take down a single battleship in the first game, a fleet of them in the second, then the trope takes a break for R-Type III and Leo before it comes back as a Humongous Mecha Raid in Delta, and then comes back with a vengeance in Final.
Bittersweet Ending: What the best ending for Final amounts to. Operation Last Dance is successful and the Bydo are wiped out for good. On the other hand, the ship responsible for dealing the killing blow ends up damaged, floating aimlessly amidst the husks of your enemies. While back on Earth, there are hints that humanity, exhausted from years of war against the Bydo may be going back to the old business of killing each other.
"Blind Idiot" Translation: The US manuals for R-Type (Game Boy) and Super R-Type are notoriously "americanized", with ridiculous enemy names and descriptions.
Boss-Only Level: The third level of the original game is one long battle against a giant alien spacecraft.
Charge Meter: Rated in 'loops' based on how many times the bar fills and restarts. Most games settled for two loops, while Final wasn't happy and bumped several up to three and four, and had one with seven. The final boss in Final actually breaks your charge meter, making it take 45 seconds to fully charge (it doesn't work at all otherwise), but devastatingly more powerful.
Check Point Starvation: Super R-Type''s levels have no checkpoints. Die once and it's back to the very beginning of the stage.
The Computer Is a Cheating Bastard: In the worst ending in Final, the enemy ships, your former allies, piloting ships like yours, all take substantially more damage than you would in their shoes.
Same thing with Delta's fake R-Series ships before Stage 6's boss. They're still easy anyway if you blow up the psuedo-Force one carries with a simple two-loop charge shot, so basically The player is a cheating bastard in this case.
R-Type II has allies that you can free from the final boss, but they also die in one hit like you, and they don't think to fire charged shots until after beating said boss.
Compilation Re-release: Only applies to R-Type and R-Type II. In case of the 1999 release of R-Type DX, the compilation was of the Game Boy versions which still omitted a few stages from the arcade version.
Continuing Is Painful: Less so than many of its contemporaries, though; the Wave Cannon is designed to mitigate this to an extent by avoiding the Gradius syndrome of going right back to a totally useless starting gun, and it only takes three weapon powerups to be back to a full-strength Force. The main difference is that rather than instantly reappearing, every R-Type but Leo uses a Check Point system, restarting the player only at fixed positions in the level. Super R-Type was the crowning moment of this, achieving infamous Fake Difficulty by having no in-level checkpoints at all.
The games, at least the first two, are made so that memorization is more important than powerups, except in a few spots like the original's stage 7's checkpoint] So if you know how to survive in a situation without powerups, and you eventually will, don't fret if you die in that situation.
Continuity Nod: R-Types, a compilation of the first two games, includes a nod to Armed Police Unit Gallop's ship with the gallery's R-11b. The R-11b is nicknamed "Gallop", has the two main weapons of the referenced game's ship, and is considered a police car.
Darker and Edgier: Seriously impressive considering that this series had you fighting the embodiment of evil from the start, but it wasn't until Delta that the graphics were advanced enough to really drive the point home.
Deadly Walls: Up until Delta, when brushing a perpendicular surface stopped killing you, even touching a wall was instant death. Very large enemy ships and wall-like Bydo still have the deadly touch, however.
Death Is a Slap on the Wrist: Sidestepping the legendary difficulty of the rest of the series by several miles, Leo features instant continues instead of checkpoints, throws powerups around like confetti and actually has you drop one when you die.
Diabolus Ex Machina: the syndrome of the human sides in both R-Type Tactics/Command games as well as the ending of Cerberus in Delta''.
Difficult, But Awesome: Handling a detached Force Pod well is not learned easily, but can really turn the tables in your favors in the end.
Difficulty By Region: R-Type II was so hard, Irem had to tone it town for the American arcade release. Just to get a taste of how bad R-Type II was, the first two levels once featured enemies that strike from behind, including the kamikazefish from the second stage. The second stage once made the Ladies, slow-moving enemies that home in on you and are VERY durable in the second loop, spawned a few seconds apart from each other rather than all at once like the American version, which allowed them to strike from behind. The fifth stage's enemies that created often-unbreakable blocks in ther wake, shoot in the Japanese version. All the stages had bosses with somewhat more health and less useful powerups. Even better, the PSX compilation that contained both this game and the original used the Japanese versions, so there's been no legal way of getting the easier version until Dimensions, unless you find one of the few arcades that still contained this game.
Leo's Japanese version can't be credit-fed as easily as the American version, since it takes you back to a checkpoint if you die. However, it does have a LOT of checkpoints for each stage, though, and its stages are barely even longer than the original games, which either provided NO checkpoints or just one.
Downer Ending: In R-Type Delta if you play as the Cerberus you don't escape the Bydo dimension and end up trapped in a Bydo plant. In R-Type Final there's only one way to beat the game that doesn't result in killing the player character, and it's ''stupidly'' hard. And just in case you thought the series was going to give you a glorious finale in which peace is restored, several ship entries in Final more or less state outright that humanity is preparing to get back to the old business of killing each other again once the Bydo are gone (and R-Type Command II: Operation Bitter Chocolate confirms this). Entries on the two last fighters, Curtain Call and Grand Finale, also hint that Earth pretty much exhausted its natural resources in the Bydo Wars. The human ending in R-Type Tactics shows the Heimdall sunk into the Bydo dimension, while the Bydo ending has your fleet realizing what they've become and getting chased off Earth by the Space Corps. The same thing happens to your human fleet in Tactics II. For those who wish to know what happened in Tactics II, the two human sides that were fighting each other joined forces to stop another Bydo invasion, which has been headed by the admiral of Tactics 1. After defeating the invasion, you human fleet encounters the Amber Eye, the new Bydo Core. After defeating it, the human fleet gets broken down completely into bits and become Bydo. After fighting an unknown civilization, a human fleet, reaching Earth and leaving, the Bydo fleet goes to the sun and encounter what seems to be a Bydo Recycler called the Solar Envoy. The Bydo fleet repels the first atttempt by the Solar Envoy to recylce you into Bydo, them commit suicide by going into the sun.
Dynamic Difficulty: The difficulty of the first two games increases when you get a Force, and increases some more every time your Force upgrades.
Earth-Shattering Kaboom: It's implied that even in the time the Bydo traveled back to, destroying planets is so routine that most large spacecraft can do it. In fact, it's also implied that the Moritz-G in Delta, a vehicle that fits on a standard highway, could completely depopulate the planet Earth. Subatomic, the rebirthed form of Dobkeratops in R-Type II/Super, is also said to have enough firepower to destroy planets.
Evil Is Visceral: All of the advanced forms of the Bydo. This includes and is not limited to: weaponized giant sperm, phallic bosses, bosses that look like vaginas, and on and on. Gomander provides one of the page images.
Excuse Plot - Every single game, even with the elaborated plots in the later games. For a long time, "Blast off and strike the evil Bydo Empire!" was as much as you got. Operation Bitter Chocolate even made it to the extreme that human infighting occurs for just the very force device accompanying the R fighters...
Fallen Hero: The ending for Cerberus in R-Type Delta has it trapped in a plant in the Bydo dimension. In R-Type Final, if you use a certain ship, you will be able to access that dimension and fight it as a boss.
This happens to your character in stage 6.1 and F-B in Final as well. You get turned into a Bydo at the end of 6.1, and are forced to fight your fleet in F-B!
Fixed Forward-Facing Weapon: Human space battleships are routinely built around a gargantuan Wave Cannon that can destroy planets. In Command, this makes up the entire bow module on the battlecruiser.
Flower Motifs: The Agrimonia seen in a wallpaper or 2 in the gallery in Final represents Irem's thankfulness for being able to keep making the games despite the lack of a profitable market, as stated in the manual.
Flunky Boss: The Stage 4Mini-Boss of III doesn't attack directly- it summons a pair of annoying indestructible turrets to fire at the player instead.
Follow the Leader: In the late 80s and early 90s, if a shooter wasn't ripping off R-Type, it was because it was busy ripping off Gradius.
For Massive Damage: Bosses are all about finding the Weak Points and learning when they are exposed and when it is safe to attack them.
Final inverts this: firing the Force into the boss's core makes it stronger. When you finally figure out that you're supposed to destroy the Force with a charged shot from your Wave Cannon, that makes the boss even stronger while utterly breaking your Wave Cannon. You then have to charge your cannon for a very long time to get enough power to destroy the Bydo once and for all.And it actually makes sense, since the Force devices are made from the Bydo, and you're trying to wipe them all out, you have to destroy your Force as well.
Humans Are Morons: In R-Type Tactics II: Operation Bitter Chocolate, while facing the menacing threat of the Eldritch Abomination Bydo Empire, the humans fight each other over whether to continue to develop the Force Device or not! Again, this is probably an Excuse Plot created by Irem in order to make players experience two types of R-Fighter battles.
Idiosyncratic Combo Levels: In a way: each beam charge level in Final is named something different, the order being "Beam", "High", "Strong", "Great", "Special", "Devil" and "Bydo".
I Have Many Names: Many bosses have multiple names throughout the series, but Dobkeratops, the iconic armless xenomorph thingy, stands at the top. As well as that name, he's gone by Subtom, Subatomic, Zabtom, Subkeratom, Krill, Doppleganger, and Gladiator.
Infinity+1 Sword: The R-902 Ragnarok II and R-13B Charon in R-Type Final. Also, the 3 Ultimate Fighters. Last Dancer, Curtain Call, and Grand Finale only vary in looks, and all pack full customizabilty: Any Wave Cannon, any Force, any Bits, any Bombs. Any weapon combination you want. Add in the color customization and you basically have the game saying "Here. Build the most epic R-Type fighter ever.''
Level In Reverse: A notoriously tricky section of R-Type III on the SNES requires you to fly through a convoluted set of pipes while dodging magma streams, fight a miniboss, then do it again backwards.
Lighter and Softer: Leo, which boasts more colorful graphics and a jazzy soundtrack, and takes the focus of the plot away from the Bydo. Its overseas release is also more forgiving than other games, respawning you in place upon death rather than using checkpoints. However, the Japanese release is a little more difficult, due to sending you back to a checkpoint every time you die. It's still pretty easy compared to some other R-Type games.
Living Statue: Final's re-appearance of the entombed Cerberus from the end of Delta.
Lost in Translation: The original Japanese manual (and website) of FINAL says that the game takes place 20 years after the first R-Type, but the English manual says it takes place 500 years later—right when the Bydo were supposed to be created, in fact. FINAL's internal clock for both versions, however, displays the date as being a hundred and sixty years ahead of the present year (so in 2004, it would display as 2164).
Magitek: Official sources have stated that the Bydo are essentially Biomagitek.
In Final, one ship (Platonic Love) has weapons powered by love. Another (Sweet Memories) has it's Wave Cannon powered by nightmares.
Meaningful Name: R-type refers to the r/K Selection Theory, and to the "Round-canopy" design of the R-9A Arrowhead. The Bydo can be considered the titular R-type strategist.
The wave cannon is so named because it is essentially a particle beam whose particles possess wave/particle duality, similar to light. This is also why the cannon is so harmful to the Bydo: their flesh also has duality, so the cannon can harm them whether they are solid or waves.
One of the ships in Final is called Cross The Rubicon: true to its original meaning (performing an action from which there's no return), it's the branching point in the ship tree where all ships below it consist of Bydo matter to some degree.
Military Mashup Machine: R-Series warships are atmospheric fighters with SSTO capability that fight just as happily in atmosphere, in space, underwater, or inside huge horrible alien monstrosities. The Force Device's weapons and the Wave Cannon also tend to handle exactly the same regardless of the medium they're firing in, though Flame-based weapons don't work underwater so good. Though they still work in space.
Mirror Boss: Sort of. Several games have you fight Bydo-infested R-Series ships, but they tend to be very weak.
Meat Moss: On certain Bydo-infected ships, such as the Bydo Unit Alpha and Bydo Unit Gamma, or ships that use bydo cell cultures for Organic Technology. In Command, it grants certain Bydo ships a Healing Factor.
Mook Maker: Most of the giant ships have at least one somewhere.
New Game+: Final only allows access to the second ending after seeing the first, and the third only after seeing the second. One level also changes to one of five possible versions depending on how the boss was attacked in the previous playthrough, and one stage can only be accessed by finishing the previous one with a particular ship.
Nice Job Breaking It, Hero: That R9 you save in stage 4 of Delta? Returned to base infected by the Bydo. By the time you get back, the whole base has been infected.
Nostalgia Level: R-Type does this constantly almost to the point of committing Game Design Incest, with one particular boss appearing in every single game but Leo, and several entire levels built specifically to reference previous ones. Delta's fifth level consists entirely of scarier versions of R-Type I enemies and situations, and Final has a stage set in the same place as the final stage of Delta.
Nothing Is Scarier: Apart from the Bydo themselves, just what was future humanity fighting that they resorted to creating the Bydo?
Organic Technology: The Bydo. They can go for full-on planet-sized bioships or capture and possess a mechanical ship wholesale without externally changing it at all. Oh, did we mention that they seem able to do this whenever they feel like it?
Then we come to the Bydo-type ships in Final.
Pacifist Run: In Delta and Final most bosses will leave or die on their own if ignored for long enough, though some will kill you instead. Pacifist runs involve killing only the latter. In addition, No-Force runs are perfectly possible and the most common type of Skill Run.
Phlebotinum Rebel: The Bydo are a type D, originally having been created by humans as an interplanetary attack force. That didn't quite work as planned.
Rewarding Vandalism: One of the originators of this trope in shoot-'em-ups, R-Type has the POW Armor, a specific enemy which carried powerups, only liberated by destroying it. It's never really established why humanity thinks it's a good idea wasting this many POW Armours, never mind how they end up in some of the places they do (Such as the alternate dimension made up entirely of Tron Lines).
Reverse Shrapnel: The R-90's Cyclone Force does this whenever it's detached, and the Bits do it too when it's using the Hyper Wave Cannon.
Robo Teching: More often than not, your laser powerups produce some physics-mooning effects with simple "lasers." Red powerups fire a pair of red and blue lasers that travel in an interlocking sinewave pattern, blue lasers bounce around the environment, and yellow powerups travel along the ground. Some games feature laser powerups that bend to hit an enemy craft. Certain wave cannon shots also do this. In Command, the Battlecruiser's laser turret fires four beams in a cross pattern that bend 90 degrees' from the emitters.note You made a scientist cry. I hope you're proud of yourself. It's implied that it has something to do with using Bydo biotech.
That's No Moon!: Bydo Lab in Final mention how they once encounter a planet-sized Gomander.
There Is No Kill Like Overkill: The Giga Wave Cannon used by "Ragnarok II" in Final. While most ships have a maximum charging of 2 levels, this one goes up to 7!!! Note that a Level 5 shot is enough to destroy most enemies (including bosses) in one hit.
Timey-Wimey Ball: Not only are the Bydo are attempting to destroy their own creators in the distant past before they are created in the first place, one of the endings to R-Type Finalinvolves traveling into the future in a ship built including Bydo technology to convince future humanity to not banish the Bydo into where it can get into the past. It's implied this doesn't work.
The implications are far worse. The 26th century people use the ship and the pilot to finalize the creation of the very first Bydo. To boot, they ignore the pilot's advice and still banish the Bydo.
Took a Level in Badass: Dobkeratops (or whatever his name happens to be) goes from being an early-game boss in the first few installments to a late-game boss in Delta. In Final, he's on life support in Stage 4.0, and you would think that this signifies Badass Decay, but only a badass would have his heart weaponized and use it as a last-ditch weapons system.
Tragic Monster: The protagonist basically becomes this in the R-13 ending of Delta, the Stage F-B of Final, and the beginning of the Bydo campaign in Command.
Transforming Mecha: The TL series can transform into mecha mode depeding on if their Force is attached or detached. This allows them to switch between 2 Wave Cannons, but the transformation has no other benefits and the last 3 ships can use their switchable Wave Cannons just fine without transforming.
