Build a civilization. Build its history. Fight for Earth’s future.
Interstellar war nearly tore reality apart. In its place, the galaxy created Era Echo—a nine-day tournament where simulated civilizations decide the fate of entire planets.
Represent Earth, build a deck, raise a civilization across nine eras, and shape your hero one decision at a time. At the end of every era, that hero becomes an Echo: a preserved version of everything you built, earned, and sacrificed.
Then history goes to war.
Create Nine Versions of One Hero
You are not building a single final character. You are creating nine distinct moments of the same hero.
Every stat increase, Building, and Tactic changes the Echo preserved at the end of that era. Invest early to keep your first Echos competitive, or save resources to create devastating versions later in the timeline. The shape of your power curve is yours to design.
Spend Your History in Hidden-Information Duels
Each of your nine Echos can fight only once per Duel. Enemy Echos are hidden, turning every matchup into a contest of scouting, timing, or even a calculated sacrifice.
Use Reveal to uncover an enemy’s era. Risk Player Health in Winpoint battles, chase valuable Treasure battles, and decide whether to commit your strongest Echo now or save it for the fight that truly matters. Once selected, the two Echos clash in a fast auto battle shaped by the builds you created.
Build a Civilization, Not Just a Deck
Choose three of five Elements—Gold, Wood, Water, Fire, and Earth—and combine their identities into a build of your own. Place Buildings on an expandable grid, create engines through positioning and adjacency, register battle Tactics, and turn economy, growth, control, destruction, or defense into combat power.
Each hero brings unique abilities, cards, and relics, while your third Element opens new synergies every run.
Survive the Nine-Day Tournament
Every day follows a complete strategic arc: develop your run, build nine Echos across the eras, then send them into the Duel. Visit shops, open card packs, discover relics, enter unpredictable Warp events, and accept dangerous Challenges for greater rewards.
Start from the Knock Out, survive to the elimination rounds and advance to the final showdown. Earn Epoch Points, unlock new heroes, cards, and relics, and return with new ways to rewrite history.
Your Past Is Your Army
No two civilizations produce the same nine Echos. No two Duels ask for the same sacrifices. Build wisely, read the enemy, get creative — and win with who you were.
