Build your own army by commanding the "Echoes" of defeated foes.
ECHO LEGION is an army-building battle game where you defeat stronger opponents through formation and organization.
■ Defeated enemies become allies
Opponents you defeat become "Echoes" and join your army. This includes the Goblin King and the giant trees of the forest. Cultivate and combine the collected Echoes to create your own unique army.
■ Defeat stronger opponents with positioning
Formation and organization are key to overturning the difference in power. The placement of front and back lines, the protagonist's position, and the compatibility between Echoes greatly influence the outcome of the battle. Records of victories against stronger opponents are recorded as "Victories Against Stronger Opponents" in the rankings.
■ As you grow, your options expand
Learn abilities with Resonance Cores and change your fighting style with Keystones. There are many places to challenge yourself: stages, trials, and season rifts.
■ With Other Commanders
Chat in the plaza, make friends, and engage in asynchronous battles against other commanders. Show off your proud army!
■ Strength is Not Sold
There is no gacha system. In-app purchases are for card appearance and features that enhance gameplay (double speed, storage slots, warehouse, lamps that increase experience and drop rates, etc.). Echoes and ability points themselves are not sold.
