Pre-register now! A tactical idle RPG where world rules change every loop. 49 tactical cards and 20 Worldlines make every run a new puzzle! The world resets, but the rules change every time. It's not you who grows stronger — it's the world itself. Aeterna Loop is a tactical idle RPG where you combine tactical cards to adapt to ever-changing Worldlines with each regression. ◆ Worldline System — Different Rules Every Loop Choose one of three Worldlines each time you regress. In "Burning Land," water attacks become devastating. In "Silent Wave," basic attacks reduce skill cooldowns. With 20 unique Worldlines, every loop becomes a fresh puzzle to solve. ◆ 49 Tactical Cards — 6-Slot Tactics Board Combine 49 cards across three categories: Acceleration, Stability, and Economy. Attack speed builds, skill nuking, lifesteal survival, gold farming — the strategies are endless. Will you go all-in with the legendary "Glass Blade," or protect your team with "Martyr's Chain"? The choice is yours. ◆ 30 Heroes — Shared Levels, Free Swaps Heroes can be freely swapped to match any situation. With the shared account level system, every hero is instantly combat-ready at full power. Save up to 5 team presets and switch with a single tap to match any Worldline. ◆ Strategic Idle — Deep Yet Relaxed Enjoy auto-battle progression without pressure, while experiencing strategic depth through card combinations and Worldline choices. Fever Mode, Gold Rush bonus waves, and bosses with unique mechanics — idle gaming that's anything but simple. ◆ Key Features • 20 Worldlines: Changing rules and rewards every loop • 49 Tactical Cards: Build your strategy with Acceleration/Stability/Economy cards • 30 Heroes: Shared levels + collection buffs make every hero valuable • 5 Elements: Water/Fire/Nature/Light/Dark affinity system • Unique Boss Mechanics: Strategic challenges that break the meta • 6 Languages: Korean, English, Japanese, Chinese (Traditional), Portuguese, Thai
