Raiden IV is one of the best old school shmups out there. This is a great port with extended modes, various stages, and the option for multiple players along with a fantastic selection of weapons. There is room for bullet hell fans, casuals, top scorers, et cetera. The graphics while a bit dated more than get the job done. I added in some FXAA from Nvidia CP as I couldn't find anything else that worked. The resolution is basically what you got in the arcade, and they have a couple themes you can use to round out your screen.

As far as shmups go this one is actually quite a looker overall. While older, the gun effects and the stages are very well thought out and increasingly more exhilerating the farther you get into each stage and more you unlock the full potential of each weapon and sub weapon. Absolutely no complaints on the weapons here. This is Raiden at its best and your arsenal is fluid, exciting, and most of the tools are totally different in control from one to another. You can play this shmup pretty much anyway you want. You also get a choice of three ships, one being a fairy lol. Got to have a little of that Gundemonium vibe or something. Classic chip tunes keep the energy flowing and your mind on the action.

For difficulty you should not be disappointed. There is the classic arcade mode, practice, easier modes, and they also added some hardcore levels of difficulty for those troopers looking to show off their insane skills. Everything here is well done and it looks like they actually cared about this port. I really cannot see any real shmup fan being disappointed with this one. It's one of the best out there and the port is excellent.

ATTENTION: Had an issue with Rivatuner/D3DOverider being turned on which caused the game not to be able to switch to fullscreen or change resolutions without freezing. Just a heads up if anyone is experiencing the same issue.

Other than that the game runs great. Has plenty of options. It does have a scarce graphics menu, but the game still looks fantastic for what it is. There's even keyboard AND controller prompts, something a bigger company like Koei Tecmo can't seem to grasp.

The game keeps things fresh by giving players different ships (and a fairy) that utilize power ups and bomb attacks in different ways while also changing ship maneuverability. I'm fan of the flagship...ship of the game personally. I find it easier to maneuver and the weapons feel great to me. The overkill system is neat and a great way for players to try and wrack up points by bring more death to those that are already dead. Although, I find my greed into trying to rack up scores by doing this gets myself killed in the process.

The difficulty of the game is unrelenting. I find it difficult even on normal settings. I can't bring myself to go any lower than that, but seeing as how I'll probably never get to the end of the game if I don't do it, I'll probably just have to swallow my pride. The game isn't very bullet helly to me. It has more to do with enemy shots moving fast as lightning and sometimes being hard see due to them blending in with the backgrounds sometimes. It might just be because I'm finally getting up in age and my eyesight just isn't as good as it used to be.

The soundtrack for the Raiden games have never really wowed me, but their pretty good and always go along with the feel of each stage. I'm more of a fan of their sound effects for their weapons than anything else and this game doesn't disappoint. I just love hearing that laser baby.

The game also has a gallery that allows you to view and play around with some of the models in the game. You unlock them through game progression and gives gamers another level of replayability. While the models look pretty rough up close, it still a nice little bonus to just mess around with.

Overall all, H2 Interactive did a fine job with their port of this game. If you're a fan of the genre in general this is one game that should be in your library. It definitely won't disappoint your if you're looking for something to fill that shoot'em up void in your heart.

Excellent port! 60FPS, resolution options up to Full HD (maybe even higher), lots of game modes and goodies, adjustable game area size...

THE Raiden game to pick up and play! Well worth the price of admission. I'll be firing this bad boy up regularly.

The Raiden series has always been a favorite of mine (though I'm a bit less partial to the Fighters spinoffs since they have what I like to call "Audience inbreeding syndrome", catering to score freaks and those who mastered the main ones specifically and becoming rather obtuse in the process). I've been wanting to play IV for forever since I don't own any of the platforms it's historically been available on, so seeing this one pop onto Steam was quite a treat!

With that in mind, the porting work is very solid - the game runs silk smooth, looks great and even has some very good gamepad support. The original Arcade version of Raiden IV (Released in 2007) runs on the Taito Type X platform, which was sort of antiquated ("Pentium 4" antiquated) even when the game first came out, so it's no surprise that the game's a pretty smooth runner... Assuming this is a direct port of the original code, anyway. Raiden IV's lineage is somewhat confusing so I'm unclear how Overkill, the PS3, and the original Type X versions of the game all relate to each other.

The gameplay's easily some of the most enjoyable shooting you'll see out of a Raiden game since Raiden II/Raiden DX, and the classic Toothpaste Laser even makes the return it didn't in Raiden III! The game's new Overkill mode takes some cues from the more score-focused games (the whole Overkill chaining setup evokes Raiden Fighters Jet's medal chaining) but the mechanics aren't nearly as obtrusive and don't need to be followed if you just want to have some fun with the new map layouts. I think this is a really happy medium between how the Classic Raiden games do things and how the Fighters games did things!

Soundtrack-wise, Go Sato (The composer from MOSS - formerly Seibu Kaihatsu) returns to revisit his chiptune compositions for Raiden I and II. He did a very good job of it (and managed to make Tragedy Flame sound less like a transparent final countdown knockoff), so the game gets some marks there! Reusing music's a little unoriginal, but all the arrangements have been meticulously done. Newcomers and series veterans alike will get some ear candy! The new game modes also include remixes by other artists.

The game's very agreeably priced and includes plenty extra over the previous ports, making it easily worth the purchase. Give it a spin if you can!

Played a few minutes of this already and I can tell you it's a great SHMUP (Shoot 'Em Up) title!
Two things you will need to navigate the bullets in this game:
1/ Ninja fast reactions to navigate dynamic bullet patterns.
2/ An elephant like memory for the static bullet patterns.

From there you have the fundamental skills which will allow you to compete with other players around the world for the highest score! The longer you live then the higher your score multiplier goes up!

Classic arcade game with classic end of level baddies too!

One thing I want though.. in this age of widescreen displays, I want a SHMUP like this (vertical scrolling) BUT utilizes the ENTIRE screen real estate.. no large areas along the left and right hand side of the screen that are vacant (I KNOW in this particular game and series as we know it because the original arcade version was a vertical screen orientation), but I think there would be a market for it ! You know? Like GigaWing.

Could you imagine something like that running at 1920x1080 or higher?
It could be very good indeed!

The Overkill mode feels like an ultra fast Raiden, If you think "Raiden Fighters Jet" you won't be far away. Yes, this game is so good. it strikes the balance between bullet hell and oldschool shmups. The new scoring system is dead simple but is just so much fun, just keep mashing that button ;D The music consist of great remixes of classic Raiden tunes. The music is pumping during stages and changes to darker tune during boss fights.
Raiden has never been a bullet-hell and always retained its very unique (read: sluggish) gameplay with fast but sparse bullet patterns. i like how playing with Fairy overcomes the inbred sluggishnes and makes a very different beast out of Raiden game.

JOYSTiCK support is the most important thing for me in any shmup. Raiden DOES work with Playstation joysitcks. Inexplicably, being a game first published on japanese Xbox360, Raiden does NOT detect xbox joysticks , both Hori and Madcatz were not functioning at all. It is a shame, because all xbox joysticks have native drivers already installed in Microsoft Windows. I suppose this issue is going to be fixed in future.

this game wil demand from you some customisation at the very beginning.
Obligatory for the better comfort of the game are:
- screen pivot (optional but highly recommended as with any other vertical shmup)
- screen size adjustment (make it big)
- resolution
- controls rebinding for keyboard users (i prefer using left hand WSAD keys for movement)

If you are passionate about playing shmups, i wholeheartedly encourage you to buy a joystick. The simple truth is , Raiden/shmups should always be plaid with a joystick. All other input methods are not fast and subtle enough. If you churned out money for one, it will serve you for years to come (unlike constantly breaking "gamer" keyboards and mouses) and you will never look back at using anything else.

I really love arcade shooters and was glad I got this on sale during the Summer sale. This is essentially a port of the XBOX 36O Edition by UFO Entertainment. Unlike Raiden III Digital Edition, this game natively supports the XBOX 360 Controller and it makes playing this game much more nicer (yes, the D pad even works for those enthusiasts )

Graphics are beautiful, they are much more improved over Raiden III and nearly has a flawless presentation (Raiden III suffered from some flickering textures in some spots of the game.) One thing I did notice is that the game does have a tendency to stutter at times when it should not, and I've not been able to see how I can get V Sync enabled to make the game more presentable. The screen tearing is annoying to a degree.

One thing I really love however, is the music, it's arcade space ship shooting music at it's best. Lot's of happy moments.

Other than the litte quirks I've mentioned, I would suggest picking this game up, only during a sale, I could not reccomend it at full price.

Replay Value
Great Soundtrack
Bullet Hell
Some things in the game that only old school players of raiden will know, aka Raiden Trad music, Raiden I music.
Smooth Controls
Insane amount of content, and can basically can be played endlessly because of some randomized elements in bullet patterns.

There are no cons, this is the best raiden game I have ever played so far, 10/10...
Best bullet hell, shmup game I've ever played.

What makes a perfect sequel? Take everything from the predecessor and go one step beyond. I spare you listing all features and gamemodes and screen options because it's listed at the describtion of the game itself and there's a ton of it. What I'm gonna try is explaining what makes Raiden to one or maybe "the" best shoot 'em up on Steam.

To sum it up it's the overall feeling of shooting your weapons and destroying stuff.The controls are very precise and the feedback you get from annihilating the enemys just feels right. Raiden IV has a high production value across-the-board.

You upgrade your ship by collecting three different types of your main weapon which get stronger as you collect more upgrades and rockets. The enemy variety is also very high. There are tanks on the ground, big ships, small ones, enemys coming over bridges and turrets on aircraft carriers. The levels are very well designed and highly detailed.
After beating a level you encounter a boss. Those are also very detailed and well animated. And they demand all your reflexes and tactical abilities to beat them.

I recommend grabbing a coffee or a cold beer and sit down with your controller to train your reflexes like an animal. This game is very enjoyable!

I have already played this game a whole bunch on the ps3, and I can confirm that this game is very much worth it if you are at least even slightly interested in the genre.

Raiden IV improves upon Raiden III in just about every aspect (namely movement speed and weapon balance), and polishes the classic Raiden-style gameplay to a mirror sheen, the shooting feels incredibly fun due to the good mix of enemies and great sound design. I'm gonna sound like an Undertale fan here, but you really should "just play it" to get a feel of how good the shooting and level design is.

This is the Overkill version as well, meaning you get a whole other game mode, which is an arrange with the titular "Overkill" scoring system which can change the way you play the game, which increases the replay value. Best of all for PC players is that this is a much better port than the Steam edition of Raiden III, with good compatibility, options and controller support.

Great shmup, good port - although not perfect. It doesn't allow many different resolutions so on my 1680x1050 monitor I need to use 1280x720 (and have to tell the nvidia drivers to stretch this to fill the screen).

Also when using a 360 pad, the mouse pointer is on the screen the whole time, though you can just move it out of the way with the mouse you shouldn't have to do that. You can get a freeware 3rd party app which auto-hides the pointer after a set amount of seconds which is also a workaround for this.

Anyway it's cheap and it's very good so I do recommend it.

Raiden Rules of Engagement:

1. Don't stay in one place for too long!
2. Use bombs *very* sparingly...or you *will* die!
3. See steps 1 & 2. You've been warned... ;-)

This game deserves its own 'old skool' arcade cabinet in Dave & Busters, smelly bars, laundromats, your grandma's basement, etc! The graphics are just super awesome, and the gameplay is awesomely tough, in typical Raiden fashion. (Btw, MOSS are the same folks who made those awesome Raiden shoot-em-ups in the 1990s...probably before you were born! haha!)

Did I mention that this game is f-ing awesome?! :-D

In summary, hats off (and many beers) to the MOSS team for making such a kick-a$$ shooter and putting it on Steam!

The music has arranged tracks from Raiden 1, 2, and DX. That automatically makes this a good game.

In all seriousness, if you've played a Raiden game, you know what to expect: big hitboxes, fast bullets, and giant purple lasers. There are a wide variety of difficulty settings, and you can set your life/bomb count in the options menu, so the game can be enjoyed by anyone regardless of how bad or good they are at shmups.

If I had one gripe, it would be that sometimes the bullets can be difficult to see, but other than that, this is a solid Raiden game I can recommend to fans of top-down shooters.

dynamic bullet hell game

the basics are simple
red: lots of bullet
blue: giant laser beam
purple: weaker laser; but snaplocks on to targets

the only gripe i have about the game is power ups floating around make it diffucult to get when there are bullets everywhere and you have to wait for the power up to switch to the color you want and even if the color power ups spawn at the same time, they can be different, making the already diffucult task more diffucult

after that the color based firepower makes the gameplay more intense and dynamic, especially in tangent with the sub weaponary, you have an excellent load out to pick from and huge swarms and massive bosses to balance out your huge arrsenal

would highly recommend, espeically with a friend

The game is a little jewel, a perfect example of superior Japanese gameplay.

BUT it it also an example of how japanese editors CAN'T DECENTLY ADAPT GAMES TO PC!


16/10 monitors not supported, only 16/9. You play with a vertical display on a small portion of the screen only.

Despite many efforts, I DID NOT manage to use my fukken portrait monitor, which would have been so perfect for this game.
Edit: it seems like I can eentually play it on a portrait monitor. But for this, I need this monitor not turned in windows settings. I gotta fukken change my windows settings for every game, or even create a blank windows profile for playing that game. Hell.

tl;dr: Take your favourite cake, slip it on the ground: yeah, that's the right feeling...

Yeah, No. Just can't get over the inability to change the screen size so you don't have the pictures on either side of the screen as a distraction. Great gameplay, I guess, and although I understand this is a port of an already excellent game on it's respective console, I wish the developers had of taken it a step further and allowed the resizing of the play area. Just my opinion.
