Evaluation

Rustil: Eternal Labyrinth Castle officially launched its v1.0 full release on March 13, 2026, graduating from Early Access. Before launch, the developer explicitly stated on February 24, 2026 that they planned to "continue updating the game to make it even better" even after the v1.0 release. That promise has been kept with a very active post-launch update cadence. Two major content updates have shipped since launch: the 1.0 full release itself on March 13, 2026, and Update 1.2.0 on July 16, 2026, which added the new "Premium Skill Tree" system, familiar enhancements, weapon skill adjustments, and drop rate improvements. In between, significant feature patches landed on June 10 (1.1.0, adding new weapons, armor, accessories, a Zhuk Forest expansion, and new game modes) and June 18 (1.1.4, adding a new Casual difficulty mode). Maintenance and balance patches have followed as recently as August 13, 2026 (Update 1.2.3), just six days before this evaluation. The developer's most recent news post (July 16, 2026) closes with: "We plan to keep bringing even more power-ups to the game in the future." No specific named future content has been announced, but the sustained cadence of substantial updates — with major additions arriving roughly every four to six weeks — combined with this stated developer intent makes clear the game is in active post-launch development. No end to development has been signaled.

About this game

Exhilarating roguelike action with monsters and swords at your command

A world where a huge castle suddenly appears.

The protagonist, Rustil, who has no memory of his past, is drawn to the labyrinthine castle.

[■Rogue-like action]

Choose your favorite ability from the souls of the heroes lying in the labyrinthine castle and acquire it.

Enjoy a variety of combat styles with one-handed swords, magic staves, gunblades, and more!

[■ Treasure Hunt]

A mysterious labyrinthine castle that changes every time you enter!
Explore its ever-shifting corridors to collect powerful equipment and recruit monsters to join your team!

Choose Your Play Style:

  • Safe Mode
    A casual exploration mode perfect for relaxed adventuring.
    Even if your exploration ends in failure, you’ll keep all the items you found.

  • Challenge Mode
    A high-stakes mode for those seeking thrill and reward.
    If you're defeated and fail to return, you'll lose all the items you were carrying.
    However, the risks come with greater rewards—rare equipment drops more frequently, and it's easier to capture high-stat monsters.
    Note: Even if you lose equipment, you may be able to buy it back from the merchant at home.

[■Monster training and battles]

All monsters in the game can be captured.

You can not only improve their abilities, but also decide their personalities in detail!

[■Speedy and exhilarating battles]

You can enjoy a variety of actions such as one-handed sword, magic staff, and bayonet!

Collect rare items and capture the labyrinth castle!
