Knights of Tartarus is a role-playing game where you enter the underworld to fight off a legendary order of knights and save the world. To have a chance, you will need monsters to teach you their spells, craft items, solve puzzles and even compete against your rival.


Explore an open world and travel into the magical monster dimension called Tartarus. You'll find many friends and not so friendly characters along the way.

There are many regions each containing unique puzzles, treasures, and enemies.

Fight against magic beasts to gain spells, crafting materials and gold. Each monster holds special and unique abilities which can be learned. Monsters also give you crafting materials for making equipment. Additionally, there are skill upgrades that can be gained by leveling up. These give you special perks like performing combo moves or becoming immune to paralysis, and much more.

Great and varied soundtrack.
Huge bosses that are difficult but fair.
A cute dog.

Good game with a few bugs

I haven’t made much progress but the game seems really good! (and I am not even a fan of classic RPGs). A few bugs however prevent it from being excellent. I initially played one hour or so. When I came back to the game the next day, it refused to open. I had to reinstall it, which meant losing my progress. Hopefully these issue will be fixed; if it wasn’t for them, this would be the perfect RPG mobile experience.

Updates broke it

I updated immediately when I saw there was a new update because some of the game’s features were bugged, like the kings flute freezing the game. Update 1.03 broke the game completely. I tapped on the app after and it just went to a black screen forever. I’ve already put a lot of time in the game, so I didn’t want to uninstall it and reinstall to try to fix it so I could keep my progress. So I just waited around until 1.04 to see if that would fix it and I wouldn’t have to lose my progress. So I was really excited to see the new update and I downloaded it immediately, only to find when I opened the game that it completely reset. Now the only option is “new game” on the menu. This may have been the worst 8 dollars I’ve ever spent.

A truly fantastic RPG that, no joke, rivals the NES’ Legend of Zelda. Interesting storyline, gorgeous 8-bit-like graphics, intuitive controls, clean menus free of distracting ornamentation, and remarkable variety of worlds to explore.

I hope they build on the success of this game and release a second campaign. If they do, I hope they keep KoT’s fundamentals: there’s a reason why the original Zelda is so beloved. “Don’t fix what isn’t broken.”

Please try the update 1.04 it should fix your issue.
