Simply amazing. One of the best bullet-hells / rogue-likes / space pirate games I've ever played. Once I start playing this game, I usually play long into the night, saying "Oh, just one more run. Just one more. One more." Before I know it, it's 4AM, and I'd have found the coolest weapon combo since I started playing the game, and had a blast doing it.

Anyone who even remotely likes shooter games or rogue-likes or bullet hells (OR, as in any of those!) will love this game. Highly recommended.

Still haven't beaten it yet btw.

Steredenn is a masterpiece.

This game is your stereotypical 2D shmup, spaceship and all, but has more challenge, better art, better gameplay, and more fun guns. I would say if you want a VERY hard shmup that is still possible, buy this game! It is worth the asking price, which is sometimes not the truth. it's satisfying to shoot, and to play, there's that oomph feeling when you kill something, and when you dodge, you feel like a god ( because MAN some things are tough to dodge ). There's also sort of a pokemon style typing system. some weapons do more damage to an enemy than others, which adds a little bit to the gameplay.

The only cons I have seen in this game is that some of the waves are impossible to not take damage against. A lot of the waves that have the laser turrets are not possible with anything other than the laser weapons or weapons that shoot bullets of a bigger hitbox, forcing you to take a little bit of damage. I'm sure there's some way of no-hitting these waves, but I have not figured out how.

Be warned, the game will kick your butt repeatedly and laugh while doing so. It's brutal, this game is NOT for "casual" players, but IS for somebody who loves the shmup and bullet hell genres!

Overall 9.8/10 great buy!

This game is awesome. The Random generation gets you the "One more time" feeling. The weapons and power ups are diverse and surprising. The juicyness effects are perfect. The sound track is great. The art work is beautiful. Just buy this game, you won't regret it!

Difficult space shooter with nice visuals, a great soundtrack, and intense gameplay. I just wish the game was easier.

Also some of the weapons are just useless, not even better than the default blaster.

I'm not really a Shmup person, but something about this one keeps drawing me back in for another bash at it. I guess maybe that it's got a lot of variety, feels tough but fair, and has you doing something different every half a minute or so to keep things lively. Good stuff.

Super fun schmup! Even the dieing is fun!

Crazy duel weapon system with perks; pick a power up after every 'boss fight'.

Fight the bosses in arena mode with your choice of weapons that you've encountered.

Daily challenges and leaderboards!

I just wish there was more of the music and a soundtrack to play externally.

Oh did I mention the pixel art is fantastic?

Awesome side scroll shooting, with random generated levels, gorgeous pixel graphics, awesome soundtrack, great ship upgrades and an insane selection of cool weapons.
It's even possible to remove the random factor by playing superplay mode, which let's the player select a 'seed' to go for scorehunt in fixed level layouts. As the game is quite hard in the beginning, this helps getting into it.

Key supplied by developer for review.
(Read on for the full review!)

The most breathtaking pixel art I've seen since I reviewed CrossCode. Absolutely glorious music, and one of the tracks sounds like the OPM battle music! Fast, frenetic gameplay. The only reason not to buy immediately is if you don't like difficulty! Like... SNES/NES level difficulty.

You've been warned.


+ Visuals: Gorgeous.
+ Music: Blissfully brutal.
+ Auidio: Satisfying sound effects.
+ Gameplay: Hellishly fun.
+ Weapons: Variety ho!
+ Difficulty: I can't get past the third wave yet.
+ Retro: Modernized.
+ Genres: Oldschool horizontal shmup roguelite? Definitely.

- Difficulty: I can't get past the third wave yet.
- OST not available in music player or as a purchaseable soundtrack on steam.

+/- Difficulty: If you can't tell, this can be positive or negative.



Welcome to: Steredenn, pronounced something like stair eden; a beautifully chaotic horizontal shmup with rogue elements. Featuring gorgeous pixel art, a health and shield system, upgrades, an impressive variety of enemy types and coordination in waves, and a multitude of weapons.

Let's dive in!


The gameplay in Steredenn is difficult. Let me be even more of a broken record. Steredenn is difficult. Could it be more difficult? Yes. Will you ever stroll through this game? No. In general, though, there are various weapons, each with their pros and cons, and even if you find one weak or hard to work with, the default blaster is very much serviceable. The dynamics between what weapon you have, what the wave spawns for you, and how these randomized elements all work together, is beautiful. Frenetic, fast, and fun.

There isn't too much time between waves and bosses, so consider them like a warmup to keep you on your toes for the real deal. Defeating a boss rewards you with the option of one of several upgrades, also randomized, which range from slightly helpful to almost essential. These won't persist if you die, and you only have one life, however, most are common enough that you won't ever go many runs without being able to get them back. The balancing act that is Steredenn's mechanics is quite impressive.

Last but not least, I really want to stress how lovely the randomized waves are. There's so much variety, from popcorn to dodging anything from lazers to asteroids or suicidal enemies converging on you. To make this even better, the bosses have set patterns, so you'll never be unfairly killed by that one cheap attack that a boss only sometimes spawns with. Steredenn is fun, and it is hard, but it is fair.


The graphics in Steredenn are gorgeous. Even if there were no animated elements, they would still be a work of art, but even the animations are beautiful and satisfying. Really, just look at the screenshots or a quick video. Even those that have a hateful bias against all these "stupid indie pixel games flooding the market" would have to be blind to not be floored by the craftmanship presented here.


The audio in Steredenn is serviceable; quite good, even. The music, however, potentially outshines even the gameplay. A satisfying mix of electro, harder rock, and crunchy metal elements, making the sound effects of the explosions and lazers and blasters all the more beautiful when thrown into this chaotic mix.

The only flaw with the audio of Steredenn is that THERE'S NO SOUNDTRACK TO BUY ON STEAM, which it entirely deserves. I hope this is an option in the future.


If you don't shy away from oldschool difficulty, or you like shootemups, just buy it.

Full price.

Buy it.

Flying through space, somewhere between a bullet hail shoot'em up and a retro classic arcade is Steredenn a game which relies on rogue-like randomized waves of enemies and quirky weapons. Steredenn is a fun space shooter that lets you switch between two weapons once you've collected a second. The levels are quick, but get longer as you progress. The real meat of the game lies in the boss battles to cap off each level.

When the game starts, your mother ship is destroyed. As its breaking out you and a few others fly out. You only get one life, but you have plenty of health and making it to the next level restores your health. Having only one life keeps the immersion that you are fighting against the odds alone. When you die there's a whole new game waiting for you. That's the rogue-like element of it all. I assume the others that fly out have their own lone randomized mission they're struggling with as well.

If you're looking for walls or anything other than space rocks, look elsewhere. Steredenn gives you full control over the screen. The only objects are projectiles, enemies, and asteroids to run into. There are even explosive asteroids that detonate when you destroy them to take surrounding enemies with them. Some asteroids have turrets mounted on them. There are even red laser beams that reflect off of space mirrors. You need to destroy the emitter first, before you destroy the mirror otherwise you might inadvertently spray yourself with a red laser beam.

In one way there's a lot of variety here with different enemies, gun cannons and red laser beams. The only problem is that within fifteen minutes of playing, I felt like I had seen everything the game has to offer. Sure there are two or so new enemies for each new level, but they all look the same. like flying dark gray walls with subtle variations. I can recognize the enemies more by their size than their appearance. Even the first few bosses look the same before they grow larger with each level further you go. With two hours into the game, I feel like at the third or forth level, the game runs out of boss diversity that the early levels have.

The boss fights are where the real bullet hail patterns come into play. The bosses may look similar, but they each have different patterns you'll need to cope with. Its several changing patterns. Once a boss runs through all the patterns, it starts from the first pattern all over again. They're diverse and rich bullet patterns that any game of the genre would be proud of. The game does a lot with fat bullets. Waves, spirals, blooms and other patterns are still here.

When you defeat a boss, it explodes in a blaze of glory, and out of its body fall a selection of five or so passive abilities to chose from. Things like +20% score, reflect damage taken by enemies, weapons break shields, +10% damage, bullets do +50% damage and get +15% drops and even one more try on a wave making it so you have two lives. A lot of these feel uninspiring. There are still interesting abilities though such as firing rockets in addition and grow a shield. I go for the ones that have more health, more damage and so on. I'm sure a lot of score attackers will go for the chains and the scores.

To keep with arcade roots, the game offers plenty of points, bonuses and chains for destroying waves of enemies rather than just enemies themselves. Its well worth your time to stop a ship from leaving the screen. Speaking of leaving the screen, if an object enters from behind, above or below your ship, it will give you a warning icon. Until one of the level starts throwing quick metiers from below you. Then your best option is to stay toward the top of the screen.

As a game, Steredenn plays well with a controller or keyboard. The movement is speedy to help you avoid those projectiles, but its still precise. Your ship's cockpit seems to be the hit box to take damage from. Big enemies, big projectiles, tiny, two-pixel hit box and you'll still get hit. The only issue that I have with the controls is hitting one button to change between weapons. You have two weapons, so it would be easier just use the second button as the second gun, but then there's an issue of collecting a new weapon replaces your old weapon. Also when you switch weapons, you need to let up off the shooting in order to shoot with the new weapon; that is unless you've collected the ability to contradict that.

There are plenty of weapons in Steredenn and all random drops from larger carrier ships. You start with a typical beam weapon with a steady flow of bullets. Each of the other weapons has its own personality. A wide spread shot weapon with bigger bullets in the middle and smaller bullets at wider angles. There's a weapon that shoots small bullets in eight directions, front, back,, up, down, and everywhere in between. It also has a focused beam that goes wherever you point it. You've got rockets that take a split second to release and homing missiles that shoot less frequently. Death lasers can be shot once, then need to recharge over time. Larger lasers have fat beams that deteriorate as you stay firing. Torpedoes have a long reload time. Flamethrowers are short range.

Then the game gets quirky with its giant saw blades and sword weapons. The shock wave makes you charge before you can release a short distance burst. The longer you hold, the greater the burst. This weapon turns boss battles into dull tedium as you can sit behind a boss while they fire forward. Some bosses still have patterns that fly directly at you rather than forward.

Next you have the bots. Gun bots and flame bots. Rather than you shooting, you launch up to three bots one at a time, then they do the shooting for you. Well then you switch to a different weapon and shoot. Its a good idea in theory, but the problem is that the bots die easy, they still need to rotate to target an enemy and when most of the enemies are flying horizontal, these bots are shooting where the enemies are rather than where they'll be. So there's a good chance the bots will miss and be ineffective overall.

While I can say its fun and interesting to find new weapons, they just feel ineffective compared to a lot of the normal tropes in shmups. That's why I've described a lot of them to you. Its just far easier to stick with your default weapon, homing missiles or the spread beam than mess with anything else. Some of the weapons move your ship slow to compensate for their power, but that's enough to justify never using them. The homing missile while under powered can still clean a screen and make boss battles easy albeit tedious and dull.

In a way Steredenn should rely on skill because of its random selection of wave patterns, but I feel like I recognize the patterns far too often. The game falls into a game of luck and chance rather than skill. Luck of what weapon drops. Luck of what passive abilities you have to chose from. Luck of which of the first bosses you fight. Some of them can feel unfair, but that's why you play again and again to learn their patterns.

There's a charm to Steredenn's production and retro style. I'd rather play a game that looks like this than a lot of other games. The backgrounds look good, but the entire game is pixelated and low resolution on purpose. Its an easy game to pick up, play and have a different yet similar experience to your last time.

In terms of other frills, there is an arena mode where you can fight each of the game's thirteen defeated boss. Steredenn makes use of online leader boards and daily challenges as well. Both good ways to keep people in the game.

For anyone looking for a quick fix of arcade action, Steredenn is a good use of your time. If anyone is looking for a polished refined experience that you can memorize everything, then look elsewhere. I'd also like to thank the Steredenn team for granting me a copy to review.

I never played "bullet hell" games, but decided to give Steredenn a try, also mainly because it has great pixel art. Oh man, this game is a brilliant procedural shooter with amazing replayability that has an high challenge level and requires quite a lot of skill to be appreciated. Considering the low price, there's really not much to complain about. The variety of the bosses, random generated levels and weapons keep the experience fresh, fight after fight. Unlocked all achievements!

Looks great with a (really) enjoyable soundtrack, heavy electronic with strong guitar rifts.
Variety of weapons and play-styles available to experiment with.
Took me about 15 hours to be able to beat the final boss and crack in the top #100 scoreboard.

It's probably the best bullet-hell game I've played, very sleek with strong identifiable colors separating ships and bullets.
Large variety of enemy types (roughly a dozen, all of which are unique).
The screen's jam packed, it's very fast paced but it never feels cheap.
