Lost Sword is a side-scrolling idle RPG developed by Codecat and published by Wemade Connect, blending Arthurian legend with anime-style visuals and a heavy dose of “waifu” charm. Released in January 2025 in South Korea, the game follows Ethan, a modern-day student who is suddenly transported to the war-torn continent of Britannia. There, he’s named the Sword Bringer, destined to retrieve the lost Holy Sword Excalibur and restore order after the rise of the False King Vortigern and the cult of Tiamat.
Gameplay revolves around auto-battling mechanics with real-time skill activations, where players manage a growing roster of female knights—each a reimagined character from Arthurian lore. While combat is largely automated, mastery comes from timing ultimate skills, managing cooldowns, and positioning units to counter enemy gimmicks. The game features over 25 chapters, rotating raid bosses, PvP arenas, and a tower mode called Oberon’s Tower.
Visually, Lost Sword leans into 2D cel-shaded animation, reminiscent of Epic Seven, with expressive character art, flashy skill cutscenes, and a generous helping of fan service. Characters are fully voiced by top-tier Japanese voice actors, enhancing immersion and emotional impact. The game is optimized for smooth performance even on older devices, with short daily tasks and regular content updates every few weeks.
