About This Game

The mysterious object that had shimmered in the blue sky for countless generations and was worshiped by men as a god was in fact a massive man-made structure. And now, the silent vigil that was thought would last forever has come to an end.

Centuries have passed since the events of RefleX and mankind has once again attained civilization. Now, ancient technology born of a twisted mind sets in motion a chain of events designed to bring divine retribution down upon mankind. The key to bring forth the annihilation is KAMUI, a fighter craft based on ‘Xaffiquel Theory” brain fusion technology. This twin-tined instrument of mankind's destruction carries a terrible secret that ironically will prove to be mankind’s only hope for salvation.

Kamui is the first title released in the "Tales of Alltynex" trilogy, a trio of 2d shoot em ups focusing on cinematic presentation, offbeat gameplay mechanics, and a strange and melancholy storyline about planetary warfare and rogue super computers.

In Kamui, players have access to a standard machine gun for destroying hordes of small enemies, a homing attack which only hits distant enemies attacking from the background, and a powerful beam weapon that focuses damage on a single target and nullifies enemy fire. The last two weapons are dependent on a recharging energy meter that must be carefully managed, because running out of energy can result in being overwhelmed. Destroying enemies with a charged homing attack also awards greater points, but requires players to leave dangerous enemies alive for longer and find perfect timings to blast them all, forcing mastery of the mechanics to achieve high scores.

I find these mechanics give Kamui a sense of chaos. Not only do players need to dodge and shoot the usual enemy formations and attack patterns found in shoot em ups, but they also need to be careful of enemies in the background and simoultaneously juggle three weapons with precise use. Beyond the mechanics, the game's actual execution of stage and boss design is refreshingly unique. Kamui has a slightly larger hitbox than most bullet hell shooters and an emphasis on agressive enemies and bosses with quirky attacks that go beyond the usual bullet ballets of the genre. The chaos and agression combine to give Kamui a very visceral feel.

There are drawbacks to Kamui's design choices, though. At times, the bullet cancelling beam dominates the game a bit too much, turning evasion into a matter of simple timing and placement instead of complex manuevering, reflex, or strategy. Playing for score alleviates this somewhat, forcing you to hold off on cancelling some attacks, but I still wish pure survival play wasn't as simplistic. I also don't like the vast amount of health players are given. The difficulty is balanced around it, but the sheer amount of life points the player has means that no matter how bad you do on any one stage, you're pretty much guaranteed not to die till at least the next stage, removing some of the tension from the game's first half.

However, when its playstyle clicks in the end game, Kamui truly shines. The last three stages offer one of the most intense and memorable climaxes in the genre, and the intensely visceral action throughout generally make up for some minor issues. For those looking for something a little different, Kamui is an excellent change of pace from shooting game norms.

Great game, one of the best SHMUPS I've ever played. If you're familiar with Layer Section/Gunlock/Raystorm, then you'll have some sort of idea of what to expect with Kamui.

As with Layer Section, the gameplay is split into two layers, the plane you're on, and everything beneath you. On your plane, you can shoot a machinegun-like weapon and a powerful laser that uses energy, but also destroys enemy bullets. On the layers beneath you, you can attack enemies with a lock-on lightning weapon - this can be used to destroy or damage enemies before they become a threat, or attack enemies shooting you from below.

The more you use the bullet-soaking beam, however, the less energy you have for the lightning attack, so it's a double-edged sword. This makes the gameplay significantly about energy management in the short term (as you do recharge quite quickly). The scoring system ties in to this, as kills with the lighting attack recieve a multiplier.

Gameplay aside, it's a nifty little game with an amazing soundtrack - and while the graphics are a bit dated, they're well made; there are really neat parallax and explosion effects to see.

If you like shmups, check out Kamui. It's a good'n.

Sometimes I wonder what anyone could see in an old game like Kamui. This STG was released in December of 1999. This was back when everyone had to walk fifteen miles through snow and broken glass, just to find quality shmups. Kamui runs at a pitifully low resolution, and there aren't any tanks that turn into robot-girls. There isn't even any fanart. Why? Because the protagonist is a brain in a ship! That isn't kawaii, not in the slightest.

Seriously though, who cares about all of that nonsense? Kamui is just as awesome as it ever was. It's a tremendous game that delivers everything fans expect from the genre. This game tends to be compared to titles like the Ray Force series, though it has other elements that help set it apart.

Risk Vs Reward is an adage older than time itself, and it's the entire basis of this game. Aside from the main cannon, your most important weapon is lightning. This weapon can be used to power an exceptionally strong laser, that also cancels enemy projectiles. However, using the laser tends to negatively impact your score. Your other weapon is the targeting bolt. Enemies destroyed by bolts offer up a multiplier bonus. Depending on how much meter you have remaining, this bonus can go as high as 16X.

While Kamui gives you a generous supply of hit-points, you're constantly putting yourself into bad situations, just to get the highest possible score. Bolts can only destroy enemies that are below you, and that applies to bosses as well. You might find yourself keeping the boss alive, allowing them more chances to kill you, just so you can get the massive multiplier bonus. As for the stages themselves, your attention is almost constantly divided, due to the prevalence of enemies both below and in-front of you. If you approach this game strictly intending to survive, then it probably won't be that difficult. However, your score will suffer, and eventually you'll give in to the temptations of 16X.

Kamui is a very short game, and doesn't make any attempt to pad things out. Each stage creates scenarios that are fresh and interesting, without straying away from the concept that drives the game. The enemies you face are varied, and the bosses employ numerous strategies in order to take you down. This isn't like some STGs, where you deal with giant pieces of garbage that do nothing but fill the screen with bullets. Every second of this game is creative and dynamic. It's loaded with energy, and has just enough challenge to keep gamers compelled.

In short, Kamui is a classic. Give it a go sometime.

Kamui is the Japanese word for divine or powerful.

This is a classic SHUMP game that I have really enjoyed so far. I have done a little research on this one, as I buy these Japanese titles a lot and usually have no idea what they are about.

So Kamui was originally released some 15 years ago as a SHUMP for the Japanese PC doujin community. The game is actually part of the Alltynex trilogy [http://alltynex.com/] with Kamui being the third game in the trilogy, but strangely enough the first one that was released to market.. go figure.

As a SHUMP it has the standard waves of enemies in a bullet-hell type environment. Using a combination of your weapons (which includes a lighting gun - which IMHO looks really cool when you fire it), power-ups and kill-streak combo(s) you can really rack up some high scores.
What I personally really like the is UNLIMITED continues so that people like me can actually finish the game.

It would appear that the game is the same as it was 15 years ago, with additional graphic and audio tweaks that bring the game in 2015 - so the DEVs should be proud of keeping the games originality intact while accessing some modern capabilities.

I picked it up in a Groupees bundle, but would have happily paid full price for it.

like SHUMPS? get it.

A very impressive Taito-inspired doujin shmup with a lot of Rayforce cues. Spectacular presentation (within its idiom). Steer clear if you hate bendy lasers though.

Steam, seriously come on! The game isn't too easy if it takes 10 continues to complete and much less it is in that case beaten. There are about twenty players that have actually beaten the game and only few thousand that have played it!

What's wrong with you people????

It’s a solid shooter loosely based off of the RAYCRISIS series (as it seems to be for 90% of shumps). I spent a decent amount of time on this and will come back.

It uses 3D graphics but doesn’t fall into the pit that Solar Shifter EX did. There was some confusion as to what to do about the ground units but i’ll figure that out.

Will return to it and finish it.

Even little details like how the stages connect together are clever in design; there’s no obligatory rolling out of background tropes like the jungle level or the factory level just so boxes can be checked. KAMUI is a seamless journey stitching each of the six stages to each other, offering a rare glimpse of chartable progress from cloud-covered sky, through depths of earth into the outer reaches of the planet to take on an orbiting weapons platform. It’s a real labour of love that not only does credit to its esteemed source material but manages to out-perform it. It’s more forgiving, more fluid, more concise.

My sole complaint about KAMUI is I do not believe you can set this game in full-screen.

Everything else about this is phenomenal. I felt like a kid in an arcade again. And the vertical elements were implemented seamlessly. :-D

It's alright for a quick playthrough. Sadly not many power ups and all the same two weapons through the whole game.
Good music and art, ok difficulty.

Kamui is a vertical 2D shoot'em up released exclusively for PC (Windows) in 1999 by japanese Indie developer Siter Skain. This game is part of the trilogy " The Tale of Alltynex " composed of the games: Kamui, Reflex and Alltynex Second. Kamui is considered one of the best shoot'em ups released for PC, something I have to agree, because the game is really great! Kamui's gameplay is heavily inspired by the games Rayforce, Raystorm and Raycrisis made by Taito Corporation. In Kamui you have three types of weapons at your disposal: the front gun that can be upgraded; the ray gun, seeking and hitting the enemy in the lower layers in relation to your ship and finally a powerful, concentrated shot that smashes the enemies, but that depends on an energy bar in a scheme similar to the classic R-Type. The game has a nice and fluid gameplay, very tasty and fun. The controls work very well with the Xbox 360 controller and the music is wonderful and very engaging! An excellent game that has my strong recommendation! To see me playing this game, please check the videos below:

KAMUI is a shmup in the same series as RefleX and ALLTYNEX Second. It has great visuals and shooting mechanics like the rest of the series and is pretty tough, although this one has an option for unlimited credits (it's the only game in the series with that to my knowledge). Like the others, it's a great entry into the genre and if you enjoy this type of game, you'll love KAMUI.

If you are a big Fan of the Japanese Arcade Shmup (Shoot em up) Genre, then This is a must have game! Especially if you are a big BIG fan games like Rayforce which is very reminisent of this game. Every bit of the game reminds me of Rayforce and Raystom from the lock-on system to the graphics itself! The graphics itself isn't great by today standards but wounderfully replicated the effects and graphics rayforce had back then. I would only recomend this game to fellow shmup fans and players out there especially the softcore ones who played games simmilar to Rayforce and other not so maniac bullet hell shooters. oh, and if you played Thunder Force V and digging it's music like me, this game will be a treat! The game uses the same PCM instruments used in Thunder Force V! I believe it's the same instruments and I love that they did that. This game brings back old 90's Shmup nostalgia to me. I wish I still have a copy of Thunder Force V and a fully functioning raystom PCB cabinet. Hopefully steam would be brining these great shmup titles like those I said earlier.

Total recommend for the STG lineups. Though I still find myself struggling against a few fights. I still found it fun as hell for the struggle though. Only thing I have to say: Curvy Lasers are the death of all.
