About Undying Fortress

Can you and your magic sword save the kingdom from death herself? Infiltrate a tower full of skeletons, decipher its secrets, and escape with your team!Undying Fortress is an interactive dark epic fantasy novel by Yeonsoo Julian Kim, author of The Fog Knows Your Name, where your choices control the story. It's entirely text-based, 500,000 words and hundreds of choices, without graphics or sound effects, and fueled by the vast, unstoppable power of your imagination.For centuries, a mysterious fortress has floated above the kingdom of Serendal. Now it has fallen—and all of its secrets, treasures, and monsters are within reach.You have fallen, too. After expulsion from the Imperial Academy cut short your studies as an aspiring knight-scholar, you turned to the life of a mercenary. Wielding your family's legendary blade, Wicked Fate, has won you a certain degree of fame and fortune, but now the ancient fortress presents the opportunity to climb much much higher. Enter the tower with a motley group: fighters, spellcasters, and thieves; former friends and mentors from the Academy; even a prince of the realm. Within lurk countless skeletons, shambling Afflicted, ferocious flying creatures cobbled together from bones, and more. Commanding them is the fearsome Carrion Mother, an ancient deity long suppressed by the royal family. Only you and your companions will learn the secrets that Serendal's rulers want to keep hidden.Fight off undead monsters to protect Serendal, or learn to wield forbidden mortuary magic and get the creatures to do your bidding. Uncover ancient secrets that may shake the realm to its core, or keep them hidden and become the power behind a new throne. Win glory with your magic sword and prove that you are worthy of knighthood, or just gather treasure to come out of this the wealthiest mercenary who ever lived.

I've almost exclusively played World of Darkness games from Choice of Games. However, Undying Fortress really piqued my interest, so I bought it right away. And I absolutely don't regret it. This is a thrilling and dynamic story with a dark atmosphere and fantastic ideas. I had a blast!

This was enjoyable, though the primary antagonist tended to seem a bit inconsistent in terms of how your options regarding her are framed. Even so, I got a really terrific ending that I liked a lot. I will say to be careful about the romance routes, I had to save scum after spending most of the game flirting with my goth baddie ex but then later I got the option to kiss my bestie so of course I did but that locked in her romance route (she literally was like "I have always loved you" and I immediately regretted it) so I reloaded an earlier save and was glad I did because my mean goth gf was endgame. Enjoyable ending, interesting story. The climax of the whole story actually reminded me a lot of Dimension20's The Seven, insofar as you're bouncing from one massive illusion to another where your comrades are facing their greatest fears and you need to help them. Anyway it's good.

I originally got this game out of passing curiosity, something to pass the time with. But the game ended up drawing me in far more than I would have expected. The narration of the game gives you great control over how the story unfolds and what kind of person your character becomes. The crux of the game makes you responsible for the lives and wellbeing of many different characters, some of which are nameless escorts and others are people of depth and backstory that you can develop close relations with. The game does not shy away from the consequences of decisions, forcing you to carefully weigh the risks of every choice as you navigate your expedition through an increasingly dangerous dungeon where there are no do-overs unless you are prepared to restart from the beginning. So what started out as a bit of pass-time reading turned into an exercise in leadership, where I could vividly feel the weight of responsibility, the intimidation of the uncertainty, and the rush of betting lives on reckless acts of desperation. Giving this simple text-based game an echo of realism that no other game in my steam library can claim to have achieved. In short, I am impressed.

This game felt like a gruelling slog but not in a negative way. The game captured the horror vibe very well and for nearly the entire story I was just waiting for my character and the group to catch a break, it made the story feel really intense at parts. I think the story telling and the characters are great and the actual adventure for the book was gripping. My only gripes are that the ending felt abrupt? I feel like it didn't really resolve much, and the secret ending especially just sort of ends without paying off alot of the major story beats. Though again the actual adventure was well worth playing through regardless.

Very good story game. The very end was a bit odd, but I know there are other routes. If you like fantasy and magic, this is worth getting.
