About Rustil: Eternal Labyrinth Castle

Rustil: Eternal Labyrinth Castle is a roguelike action title where players explore a ever‑shifting castle filled with monsters and loot. The amnesiac hero Rustil gathers abilities from fallen heroes and wields a range of weapons such as swords, staves, and gunblades. The game offers two play styles—Safe Mode, which preserves collected items after a failed run, and Challenge Mode, which risks loss of gear for higher reward drops. All monsters can be captured, trained, and customized, adding depth to combat and team building.

01 / THE GUIDE

Play Modes

Safe Mode provides a relaxed experience where items found during exploration are retained even after a defeat. This mode suits players who prefer steady progression without the pressure of permanent loss. Challenge Mode raises the stakes: defeat results in losing carried items, but the mode yields rarer equipment and makes high‑stat monster captures easier. Lost gear may be repurchasable from the home merchant.

  • Try Safe Mode first to learn castle layouts before tackling Challenge Mode.
  • In Challenge Mode, prioritize capturing strong monsters early to offset potential item loss.

02 / THE GUIDE

Ability Acquisition

Players choose abilities from the souls of heroes discovered within the labyrinthine castle. These abilities enable varied combat styles, letting you switch between one‑handed swords, magic staves, and gunblades. The system encourages experimentation, as each new ability can dramatically change how you approach enemies and obstacles.

  • Mix melee and ranged abilities to handle diverse enemy types.
  • Swap abilities after each run to discover synergistic combos.

Monster Capture & Training

Every monster encountered can be captured and added to your team. Captured monsters can have their abilities improved and their personalities customized in detail, influencing battle behavior. A well‑trained monster roster provides strategic options beyond the protagonist’s own weapon choices.

  • Capture a variety of monster types to cover different combat roles.
  • Adjust monster personalities to match your preferred battle tactics.

04 / THE GUIDE

Loot and Equipment

The castle’s corridors shift each entry, offering fresh opportunities to find powerful equipment. Rare items are more common in Challenge Mode, rewarding risk‑taking players. If equipment is lost, the home merchant may allow repurchase, offering a chance to recover lost gear.

  • Focus on rooms with higher loot density when in Challenge Mode.
  • Check the merchant’s inventory regularly for lost gear you can buy back.

05 / THE GUIDE

Controller Support

Rustil: Eternal Labyrinth Castle includes full controller support and recommends using a gamepad for the best experience. DualShock controllers are specifically listed among the supported devices. While the game is playable with a controller, no additional input methods are detailed beyond this support.

  • Use a DualShock controller to align with the recommended setup.
  • If the default controls feel uncomfortable, try adjusting your grip or how you hold the controller.
