Rustil: Eternal Labyrinth Castle is an action roguelike indie game for PC in which players guide the amnesiac protagonist Rustil through a massive, ever-changing castle filled with the souls of fallen heroes. Each run involves combat against monsters using a range of weapons, collecting equipment, and recruiting allies while uncovering fragments of the castle's mysteries and Rustil's own past. The game blends fast-paced action with roguelike progression, allowing players to experiment with different ability combinations drawn from hero souls.
Gameplay
Core combat revolves around acquiring abilities from the souls of legendary heroes encountered in the labyrinth. These abilities pair with weapons such as one-handed swords, magic staves, and gunblades to create varied attack styles and combos. Players explore procedurally shifting corridors on each entry, hunting for powerful gear and opportunities to capture monsters. Captured monsters can be trained, customized with detailed personality traits, and summoned into battle as companions. A home base serves as a hub for managing inventory, interacting with merchants, and preparing for the next expedition. The system supports both aggressive runs focused on high-risk rewards and steadier exploration that emphasizes collection and preparation.
Game Modes
Safe Mode provides a relaxed approach to exploration where collected items remain available even after a failed run, making it suitable for learning mechanics and building up resources gradually. Challenge Mode raises the stakes by causing the loss of carried items upon defeat, yet it increases the frequency of rare equipment drops and improves chances of capturing stronger monsters. Story Mode, introduced with the full release, follows a guided narrative path through the castle guided by the fairy Kotryn, with encounters that reveal lore about the setting and the protagonist. Additional features include an online battle mode for competitive play against others and support for free camera perspectives during certain activities.
Progression and Updates
Players advance by reaching deeper floors, acquiring rarer hero abilities with varying rarities, and expanding their monster team. The full release added new areas such as the Ruined City, a technology-infused zone with robotic enemies, along with new heroic souls like Zera Linfa who brings crafting-focused abilities. Subsequent updates have introduced new weapons, armor options, hairstyles, and quality-of-life improvements including expanded item capacity, refined floor layouts, and systems for recording progress to resume explorations from similar states. High-difficulty floors and endless exploration options encourage repeated runs with escalating challenges and rewards.
Is It Worth Playing?
The game suits players who enjoy roguelike action with monster collection elements and experimentation across weapon and ability builds. Its mixed to mostly positive reception highlights strengths in combat variety and companion systems, while noting occasional performance issues in some sessions. Full release support continues with regular additions to content and balance adjustments. Those seeking a single-player experience with optional competitive elements and steady character growth through repeated castle runs will find consistent engagement, particularly if they appreciate anime-style presentation and customizable team strategies. The base experience stands on its own without reliance on additional purchases for core progression.
