Our take on Rustil: Eternal Labyrinth Castle

Rather than focusing only on the protagonist’s combat abilities, the game includes monster capture, training, and summoning. It also offers two expedition modes with different failure consequences: one preserves found items, while the other puts carried equipment at risk in exchange for increased rewards.

What is Rustil: Eternal Labyrinth Castle?

Rustil: Eternal Labyrinth Castle is a roguelike action game set in a huge labyrinth castle that changes each time Rustil enters.

Rustil collects abilities from the souls of heroes lying inside and fights with weapons such as one-handed swords, magic staves, and gunblades. Expeditions involve collecting equipment and recruiting monsters. Every monster can be captured, trained, and summoned, and its personality can be set in detail. Safe Mode keeps found items when an expedition ends in failure.

In Challenge Mode, failing to return means losing carried items, but rare equipment drops more often and high-stat monsters are easier to capture. A home merchant may allow lost equipment to be bought back. Rustil aims to strengthen and reach the castle’s top floor.
