ECHO - is a third-person sci-fi adventure action game with an unusual and interesting plot.

Events take place in the future. The main character is a girl named En. Waking up from a long artificial sleep, she turns out to be completely lonely. All her friends and acquaintances have long since died. This is partly her fault.

Hoping to revive life, En enters the Palace - a huge spaceship created by an ancient civilization. However, everything did not go as planned. After the system is activated, the Palace starts creating clones of En who try to capture her. At first, they are very clumsy and do not pose a serious danger. But with each automatic system restart, En clones become more nimble.

It is noteworthy that the actions of the clones depend on the actions of the heroine herself. And if she, for example, dares to use a firearm, after another reboot, new clones will also shoot at her.
