For millennia uncounted humanity has struggled against nightmarish creatures hidden in the shadows of Creation. Though these Godless monstrosities are whispered to be legion, none share a more intertwined destiny with mankind than the Non-Human. Origins lost to antiquity, an instinctual desire drives humanity to eradicate them to the last, for influence between the two species breeds a parasitic self-destructive existence. Thus a war of genocide has waged in secret, in which the ranks of Non-Human suffer rapid extinction in the wake of human supremacy. Yet mankind’s final victory is not inevitable, for a guarded prophecy claims a messiah born unto the Non-Human shall deliver them into salvation: a fate which could only mean humanity’s damnation.
Gun-Katana (銃刀 Non-Human-Killer) is a mystery action eroge with extensive FPS mechanics, published by Black Cyc in 2007. The title has a canonical short story prequel which is available in the limited edition version.

As much a first person shooter as it is an adult visual novel, Gun-Katana is undoubtedly one of the most ambitious eroge titles conceived. It should come as no surprise that such unique vision for an adult game is the fruition of Black Cyc, a company well known for thinking outside the box in providing unique gameplay. Yet the audacity of combining two completely unalike formats in a single package understandably raises important questions. Did Black Cyc bite off more than they could chew? Should anyone think individuals who specialize in the creation violent dating games could produce a worthwhile FPS? Would the incorporation of such an original “gimmick” hinder the traditional eroge features? The answer is a complex one, and strongly mired in personal expectations of what a small budget company can (or even should) provide. Given the incredibly varied opinions this reviewer has seen on relevant Japanese message boards, which simultaneously praise and decry the title in a single statement, judgment is clearly difficult to pass. Yet at the end of the day there’s no question this title stands alone among its eroge brethren as something different and wholly unique.

I won’t beat around the bush: outside of Black Cyc’s reputation for releasing deliciously vicious ero, it’s the FPS aspect of the title that draws the most interest in a potential customer, and therefore the item I should elaborate upon first. While Gun-Katana is groundbreaking within the genre for offering such a feature, the shooter engine itself is nowhere near the breathtaking quality of the latest Half-Life or Medal of Honor. For all intents and purposes, the FPS within the eroge is merely a higher resolution Wolfenstein 3D with the addition of voice acting, larger access to different weapons, more accessible stages, and other miscellaneous (though creative) knickknacks. Therefore anyone expecting jaw-dropping graphics, profound level design, realistic enemy intelligence, or even the ability to shoot above and below themselves will be disappointed. Incredibly disappointed. This having been said: those who are open to the idea of “retro gaming” will not find the experience lacking. Though conceptually modeled on Wolfenstein 3D, by no means is Gun-Katana merely a third rate clone, occasionally exceeding it’s American ancestor. Where as the id Software juggernaut focused itself on the notion of conserving ammo and avoiding unnecessary battles, Black Cyc altered the paragram towards expenditure of ammo into the thousands while exterminating an infinite horde of monsters that embodies the lemming mentality of a Zerg Rush. Is it fun? Unbelievably so. Adding further to the destructive joy is a vast selection of weapons and items you can amass (not to mention dozens upon dozens of achievement awards). Admittedly, killing thousands of creatures that generally look the same can become monotonous after fifteen minutes of continuous slaughter. If someone were to attempt completing the title within one sitting, that individual would grow bored after three or four hours.

The mission selector (so to speak) is a variation of the pick your destination format found in MinDeaD BlooD. Each day you are provided several locations on an urbanized island to explore, the quantity and frequency dependant on your performance during FPS segments, in combination with responses provided during character interactions. Complicating this is the prerequisite of visiting areas in specific sequential order to unlock various plotlines: an element with an unforgiving small margin of error, due to an in-game countdown of 30 days before an incident (which notably remains a mystery until certain objectives are uncovered) forces evacuation from the island. Ultimately this arrangement makes everything easy to navigate yet difficult to progress, as many choices and achievements will be blindly performed until the player recognizes what actions unlock specific story paths. Between the map interface and FPS portions of Gun-Katana, resides the traditional paper doll and choose your response interaction that have become the hallmarks of bishoujo gaming. This is where the majority of character relations, plot development and cinematic illustrations are unmasked; although healthy contributions are found within FPS segments, mostly due in part to radio “battle chatter” while you’re busily killing mindless monstrosities by the untold thousands.

Thanks to the complexity of plot arcs and story strings, it’s almost impossible to describe the basic narrative of Gun-Katana without revealing slight spoilers. Truth be told, even the official site reveals a bit more than it should. The player controlled protagonist is Tokiwara Himena, who witnessed the murder of her parents by a paramilitary strike team and was subsequently incarcerated in Hatebreed: a prison facility that trains its prisoners to hunt quasi-supernatural creatures known as Non-Human. The majority of these inmates are not guilty of criminal wrongdoing; merely being somehow aware of Non-Human existence (voluntarily or not), information violently suppressed by governments and organizations throughout the world. The root cause of Himena’s suffering is her stepbrother Tokiwara Hyou, captured target of the raid, cursed with a Non-Human heritage. During their years of imprisonment, the siblings are trained and tortured through hellish environments to become professional assassins. Eventually the pair leaves the Hatebreed institution, merely to literally trade one shackle for another: the kind that detonates with explosive nanomachines if the prisoner attempts escape or tampers with the collar. This employer is Slayer, one of the most powerful Non-Human extermination groups on Earth.

It is within the Slayer organization that Himena learns how individuals can earn their freedom: each time an enslaved Slayer kills Non-Human, that individual earns a set number of points dictated by the danger level of the target, which is recorded and displayed on the explosive collar’s numeric indicator. These points are used to buy ammunition, boarding, equipment, food, and weapons: nothing in life is free after all. More importantly however, anyone able to max out the counter may purchase the collar’s disable codes and find release from slavery without strings attached. It goes without saying, that this is everyone’s ultimate goal. Unfortunately for Himena, she fouls an important extermination assignment during the dangerous career, and as punishment has her collar zeroized. Obviously dejected and desperate, Himena is thereafter informed of a highly dangerous Non-Human breeding ground that provides minimal Slayer survival odds, due to the endless population of Non-Human, therefore limitless point farming: Demon Gate Isle. Thus with the arrival of the heroine and her brother on island, our quest truly begins. From a simplistic standpoint, you have two main purposes in Gun-Katana: discover the truth and survive nonstop backstabbing. It doesn’t take long to deduce that each and every person the player encounters has their own secret agenda, which more often than not will result in Himena and Hyou having a bad retirement. Trusting no one would be sound advice, for everything takes perverse pleasure in unfolding maniac paranoia and murderous twists. Yet in cold irony only through an allegiance can the Tokiwara siblings see another day: choose your enemies wisely.

No matter the angle it’s tackled from, Gun-Katana is a masterpiece of sensual presentation that embodies the culmination of Black Cyc’s decade long experience in eroge. Even ignoring the unprecedented FPS elements: the title is audio, visual and erotica perfection given form. Character designs are vibrantly unique yet deliciously gothic, several of which are easily memorable from appearance alone. This should come as no surprise, as the artist responsible is the same veteran who contributed to Gore Screaming Show. A better choice couldn’t have been made. Paper dolls enjoy a lavish library of body positions and facial expressions, backgrounds illustrations are reminiscent of mural paintings, while event illustrations are blessed with an unprecedented attention to detail and ingenious layout. Music and sound effects are no less extravagant. An individual is very hard pressed to find a non-Black Cyc soundtrack as professionally polished with such mood driven excellence. I’ve said it once, and I’ll say it again: “Look out Castlevania! You’ve got competition.” Voice acting is supplied by veterans of the genre, with the entire cast having every line and verse spoken with genuine performance. Each character, no matter how great or insignificant, is perfectly matched with an actor or actress who brings out the best. At times the cries for mercy and death screams sound hauntingly authentic. Crowning this magnificent queen are forty-four scenes of dark and twisted erotic that cover every spectrum of fetish at least once. Bestiality? Bukkake? Guro? Incest? Loli? Tentacle rape? Traps? Twincest? These are only the tip of the iceberg.

Gun-Katana deserves every ounce of glorious praise, but the title is far from perfect, no matter how much I’d wish it to be. The FPS engine is visually appealing, yet suffers from unpolished setbacks: enemies look like cardboard cutouts, you can only shoot from side to side, the AI is incredibly stupid, and the numerous weapons are essentially identical (only with different rates of fire and damage). The title provides multiple endings, but there’s little effort in explaining how those endings can be achieved, thus the player is frustratingly forced into guessing what to do next. The dialog and transcript are awesome, but things can stretch a bit too long from time to time. Several story items are also left unexplained or vaguely handled. Even if a sequel is forthcoming, which at present is not the case, this leaves loopholes. Last but certainly not least is the matter of sex. For a Black Cyc game, Gun-Katana is surprisingly tame. Oh there’s bestiality, guro, rape, and whatever else twisted fetish you’ll desire: it’s just these offerings are not the same shock level as previous company titles. Be it due to political pressure or the studio seeking new image direction, the stance change is a tad disappointing. Yet for all these misgivings, even combined and multiplied, there is nothing like Gun-Katana on the ero market. No Darksider worth his or her weight in deviant filth should pass up on this opportunity of hentai history making.

— Scored Summary —
Scenario: 23 out of 30. A riddle, wrapped in a mystery, inside an enigma: no better phrase best describes the overall saga of this eroge. While not a suspense story per se, unknown factors must be uncovered before an understanding of the bigger picture is grasped. In total there are eleven endings, several of which dependant on which faction you choose to side with. Not all conclude happily however, and some story elements are never satisfactorily resolved. The cast of protagonists are a memorable and badass group, yet the collection of antagonists are… well… pathetic anticlimactic second string evil. There’s no Sephiroth or Agent Smith level of coolness to them.
Visual: 18 out of 20. The only situation artwork stagers, is within the FPS engine. Outside of this there is nothing to question or complain. Flawless backgrounds, awesome character designs, numerous paper dolls, incredible layouts – the list just goes on and on. As for the FPS grievance? Read about it below.
Audio: 20 out of 20. When Black Cyc puts serious effort into it, their command of music and voice acting ranks among the industry’s best. An entire cast is magnificently voiced. The gothic themed soundtrack is of phenomenal quality, equaling those found in the best mainstream console titles. The massive sound library is dead on target. What more could anyone ask for? Absolutely nothing.
Erotica: 20 out of 30. You want sex? You’ve got sex: forty-four times of it. Dark. Evil. Vicious. It has to be noted however, that the erotica is not as prevalent or “over the top” as prior company releases. Of course this is like complaining that 18-kart gold isn’t pure enough, but a hardcore veteran will notice it.
Mechanics: +10 bonus. If you’ve played Wolfenstein 3D, then you know exactly what to expect. If that legendary shooter is unknown to you, I’d strongly suggest looking it up. With exception to minor mechanical enhancements (i.e. wielding a sword to kill close range) and the insane horde of enemies with an equally insane count of ammo, the FPS aspect of this ero is merely Wolfenstein 3D on steroids. It also shares all the limitations. You can’t shoot up or down: to hit something above, you’ll have to find an equal height ledge. The AI is simplistic “Point A to Point B” programming: the monsters always know your location and eternally try to reach it (easily being trapped behind walls and obstacles in the process). Enemies will randomly respawn behind you after reaching certain checkpoints. Not too surprisingly, this is where artwork quality slips. Due to old school fog effects, the horizon of stage environments have “haze filters” to limit viewing distance. Whenever the player approaches enemies – or more likely is swarmed by them – they’re literally PNG cardboard cutouts. The endless mazes and labyrinths are statically laid out, created using 1990-ish map tile techniques. Although these kinds of “cheapo quality” situations run rampant, take this into consideration: it is the first and only FPS eroge. The mere achievement of creating a working format that also carries (even surpassing) the same greatness that made Wolfenstein 3D a legend, is an exemplary accomplishment in of itself. What could have been a typical “choose your response” menu system that most eroge share, was instead shaped as into an authentic action title. Relish that notion.
Final Score: 91 out of 100. Gun-Katana kicks serious ass. It stumbles and suffers from pitfalls, but the overall presentation with an endless list of things done right, greatly outweigh the negatives. The shooter aspect of this title is where many will question the eroge’s worth: a problem easily solved by downloading the official trail demo. If you’re not taken aback by the antiquated gameplay and graphics (or simply terrible at shooter games), there’s no reason why Gun-Katana will not bring hours of entertainment. Ero fans have a history of consistently complaining the market needs originality and innovation. Well here it is: all in gothic splendor. Strongly recommended for purchase.

You said A): “Some story elements are never satisfactorily resolved” and B): “Erotica is not as prevalent or over the top as prior company releases”: does it mean that A): a few endings (how many?) suck and B): Sex Quality&Variety is sacrificed to Story Quality&Variety (not necessarily a bad thing, but usually I buy EROge with the ERO on mind… )?
VERY NICE review, however.
February 15th, 2009 at 7:33 pm
Thanks for doing this review!I’ve played the game. I don’t understand Japanese that well and I didn’t get very far because of that. But I did find a 100% clear data patch. I find the gore level to be on par with GSS. Love the music to death!
I agree with you! This game is one of a kind. I got sick of the FPS elements after a while. But it’s definitely a nice change from clicking and reading text.
February 16th, 2009 at 7:07 pm
@Baldo: There are 11 possible endings. Compared to other Black Cyc titles, the amount of sex is fundametally on par with Before Dawn Daybreak, Gore Screaming Show, or Yami no Koe Zero. It is NOT like Extravaganza, MinDeaD BlooD, or Mushi Tsukai Shokaiban – which were REAL sexfest to the extreme. Gun-Katana has a lot of sex, but it’s just not as much or as long as other Black Cyc offerings.
February 17th, 2009 at 7:16 am
Narg@
Thanks for the quick answer! If Gun Katana if really blessed with “a lot of sex”, I think that it will definitely enter in my Wishlist, I haven’t played Wolfenstein but I’ve IMMENSELY enjoyed my time with the old Turok shooters for N64, and the gameplay here looks similar.
And about my question “A)”, of those 11 endings, how many “suck” or are somehow unsatisfactorily?
February 17th, 2009 at 11:39 am
@Baldo: Sorry. I missed that part. Of the 11 endings, three are the “OMG that’s so badass I have to see it again” type. Four fall into the average category; not exactly memorable but interesting. Unfortunately three fall into a WTF deal that caused me to scratch my head – it was like they were thrown in there to reach a quota. The 11th ending is really just an “alternative version” of another.
February 17th, 2009 at 12:59 pm
If 70% of the endings (and the story) is of at least average category, it remains a good deal.
Gun Katana is now part of my Things To Buy list, thank you very much for your time.
February 18th, 2009 at 11:30 am
I’ve played this some time ago, but I never got the Freedom ending (or was it the Freedom dash ending? either way it’s the harder one of the two to get), I tried searching for walkthroughs but they didn’t help me much. I guess I was missing something, as the choice never appeared when I bought FREEDOM.
So, I was wondering if that ending is worth the trouble of trying to get into the game again to reach it, as I really loved the game and it kinda left me wanting to finish it 100%, but I don’t really want to go through the trouble to get an average ending.
February 18th, 2009 at 2:48 pm
@Toru: There’s actually a bug that prevents getting both Freedom endings, unless you’re patched to the latest version. Freedom -Dash- is one of the possible happy endings in the game. It ranks about second in terms of “feeling good about yourself” when compared to Europe. I’m a morbid kind of guy, so I’m not into happiness. The following link explains what requirements are needed to unlock each ending (spoilerific of course): http://www39.atwiki.jp/bcyc_gkt/pages/17.html

Just checked the Black Cyc site, and I’ve noticed that Gun Katana has TWO “canonical short story prequels”.
The first is the one coming with the Limited Edition version:
http://erogamescape.dyndns.org/~ap2/ero/toukei_kaiseki/game.php?game=9522
But there is also a prequel(?) that was available for preorders from a specific Japanese shop:
http://erogamescape.dyndns.org/~ap2/ero/toukei_kaiseki/game.php?game=9815
http://www.cyc-soft.com/b-cyc-pro/gun/g_tokuten.htm#02
I totally HATE these “preorder bonuses”, a shameless way to drain more money from the customers if you ask me. Narg, can you tell us something more about these extras too? Are they independent games or simply expansions of the main game? And, most importantly, how good they are?
April 14th, 2009 at 5:08 pm
@Baldo: I only have the prequel bonus that came with the LE. It’s actually a mini-prequel to the main game, and offers a bit of insight into the Tokiwara’s lifestyle as Slayer. It’s not vital to own, but adds more depth to the gaming experience. Usually BCyc doesn’t have the preorder bonus actually linked to the game itself (more like alternate reality what-if type things), so the change is a bit unusual for them. I also agree that “punishing” people for not getting the preorder, kinda sucks… but I think we’re supposed to view it a “reward” and all that, since bgames tend to make the most sales during the first few weeks after release.
April 19th, 2009 at 2:39 pm
“Punishing people for not getting the preorder kinda sucks…. ” indeed, I will definitely order an USED copy in the fairly FAR future, if FDJP still works…
http://www.comshop.ne.jp/items/item-70040.html
Thanks for the info, however.
April 22nd, 2009 at 7:40 pm
Bloodevelen and Gore Screaming Show do look quite alike… Anyway, the murderous loli’s are very weird…
May 16th, 2009 at 2:08 am
Am I supposed to purchase “freedom” from the shop to enter freedom route, and if yes, how? I’ve completed all requirements for the freedom route (not dash, the harder one), but there’s no shop since Mito is dead…
And I want the freedom end, not freedom dash end, is that ending better than dash?
August 31st, 2009 at 2:11 pm
The monster sprites are in 2D which doesn’t suit well with the map. It doesn’t bite you or do some offensive moves as well.
No boss monsters to fight against.
The ELS can be easily hacked.
