Empyrean

Overthrow your father's regime with his own secret experimental fighter plane! Dogfight dieselpunk aeros to save your city and the iron jungle beneath it.
"Empyrean" is an interactive "flying ace" novel by Kyle Marquis where your choices control the story. It's entirely text-based--325,000 words, without graphics or sound effects--and fueled by the vast, unstoppable power of your imagination.

Far below the city of Actorius lies the mysterious world of the Deep Tech--creatures and plants both living and mechanical, and powered by unknown forces. Your father harvests the tech to create experimental airships, and the Revolution that fights his every move races to do the same. Your father's aero, the Empyrean, is governed by Deep Tech dynamics not even he understands.

Only you can fly the Empyrean, match wits against ruthless oligarchs and devious spies, and take to the sky to fight your city’s enemies. But who is the enemy? The Revolution, or the government they say is corrupt? Foreign invaders, or the Deep Tech itself?

In a world of gleaming towers and downtrodden laborers, streaking aeros and deadly rooftop duels, when you risk it all, the sky's the limit!


• Fly the Empyrean, the greatest aircraft ever designed
• Play as a man, a woman, or nonbinary; romance men or women.
• Explore the Deep Tech, a savage mechanical ecosystem below your city.
• Conceal your true identity from your family and the secret police.
• Befriend Wesh, a denizen of the Deep Tech who is both human and machine
• Cross swords in top secret research facilities, elegant cafés, and even atop airplanes in flight!
• Use the Deep Tech and your political authority to improve and protect your city
• Side with the revolution, the government, foreign powers, or the Deep Tech itself!

Excellent story, well developed characters. Outcomes respond to attribute profiles, good opportunities to develop traits throughout the course of the game, with choices that clearly correspond to one or another trait(s) and also make sense within context. Would love to see more from this author. I would definitely pay commensurately more for a longer version. Only thing i would change is to offer option of having attribute changes noted after each change, like in some other CoGs.

Okay story, but it feels unbalanced. Your stats change too easy, and the options arent well written so you know which stat is being used. For example: you might find an option that says, "if you are quick enough you could repair this or that". Does that option judge your finesse or technical skill? It is very easy to accidentally screw up.

ABSOLUTELY great, UNTIL the ending! The ending (for me at least) was terrible. I succeeded in everything I tried during the game. But at the end I just crashed and died! Oh, but Wesh said I was a great person, so that makes up for it, right? Lol. Just seems like choices don't match up with the correct skill, or worse, skills don't matter that much. Would be a 5 star if this game had even a bad ending. This ending was like worst EVER!

Okay, I just wanna say...That we NEED more great, oustanding, detailed games with the general, overall theme of the 'ace pilot' (one of my favorite military-related tropes, honestly) and warfare stories, like this one...Maybe one in set in a Voltron:Legendary Defender or Gundam-series-esque type of a setting? Just a suggestion, of course. ☺.

I highly recommend this game. The story is very interesting and the author writing skill is high. While choice changes the story properly, and the endings are plenty.

It's a really well written game, with memorable dialogue, action, and characters. But it is HARD. As someone who has been playing these games for close to 7 years now, this is the most confused and challenged I've ever been playing a CoG game. Still, I need to commend the writer on a job well done. 4.5 stars.

Perhaps the latest update has helped, but this simply is one of the best from CoG. An amazing diesel-punk fantasy interactive fiction that revolves around politics and wars. Dark and gritty, but amazing nonetheless.

A gripping story with compelling choices

A very good story, although the final fight and epilogue left something to be desired.

Tal. C. Jun 25, 2021     

THIS IS BULL, THEY FORCE ME INTO THE REVELUTIONARY....THIS GAME IS TRASH.....ALSO WHATS THE POINT OF GIVING ME AN OPTION TO DO SOMETHING AND NOT LET ME DO IT, I FEEL LIKE MOST CHOICES I MAKE DON'T MATTER AT ALL....... but a tiny black disc at the base of your skull. You could hide it with a scarf or a raised collar WOULDN'T MY HAIR COVER IT ESPECIALLY SINCE I HAVE A FEMALE CHARACTER.........but then the old woman notices the trode at the base of your skull. MY FEMALE CHARACTER HAS HAIR RIGHT🤬😡

There seems to be one problem, why can't I dance with Lectini at the soiree?

I don't want to be a rebel. I want to be part of the regime and be a cruel leader

Very cool

I actually purchased this book.The author built a unique world with a Steampunk feel: with Combines [the ruling class], the Resistance and Deeptech [think underground ancient technology].The Empyrean is a flying machine called an Aero built using the Deeptech.This story has dog fights, rival airmen and competing factions.The ending is abrupt and could have had more detail about what happens afterwards. The stats work well but they are not intuitive. Use the show stats to assist decision making.

This game is amazing. Great writing, impactful choices with branching paths and excellent prose and characters.

Easily one of this developer's best works. The setting is great for fans of dieselpunk, and the characters are quite interesting. The story, while not that original, has good pacing and keep you hooked in. Overall, well worth the price. A little request: it would be good to have a feature where you can see what stats each choice you make in the game will impact after finishing the game at least once.

The tagline alone sold me with this game. I played it several times then wrote a campaign based on the adventure for Fate Core; my players are the Revolutionaries helping my hero to do the right thing. Thank you for a game that has kept me riveted and obsessed since I bought it in early 2017. I have just discovered the update on my Steam copy, this is going to be interesting to check out!

I've gone through quite a few COG's, even bought a few COG games I disliked only to see if I could grow to like them. So trust me when I say this may very well be the best COG out there. I encourage anyone and everyone to give it a solid good try, you won't regret it.

Lor. G. Jun 17, 2018     

Simply put it Drags it takes so long on getting anywhere that if you stay around that long you find all the other problems. The traits are next to impossible to predict or to even care about unlike so many of the other stories written by this same group. The other characters are started so bad (because the dragging) by the time they seem the least bit interesting your in the final act. All in all really subpar not worth $5

Joe. H. Feb 1, 2018     

Really liked this one--vividly drawn world, strong plot, engaging characters. The choice to make the stats opposed (eg an increase in Tech decreased Sensitivity) seemed a bit arbitrary, and it was hard at times to tell what choice would affect a stat -- but the gameplay was still interesting, and the story elements thoroughly enjoyable.

Empyrean is a really addicting app to play through. Really love the concept and characters. The choices are numerous and always make me replay out of curiousity of the consequences associated with the other choices. I agree with the review below, I'd love to play a prequel or a sequel. It's just that good.

Cae. M. May 16, 2017     

Probably the best Choice of Game yet. I recommend giving it a read. It feels longer and more fulfilling than most. The choices are meaningful and have clear, long-lasting consequences. I've read through several endings and I'm always finding something new and interesting I didn't see on a previous read.

Jac. L. May 11, 2017     

Ama to the zing. Loved dat story, dem characters, dem fights, so guuuud. Only prob was I didn't like the VERY ending. But I think MY ending was specific to the choices I made prior. So over all this game was quite noice.
