About this game

In a future where technology converting human memories into digital data for storage and restoration has become commercially available,

People use `MEMORY ARCHIVE` to back up important memories left in the brain's neural networks or to restore damaged memories.

Seven years ago, a secret project called `PROJECT ECHO` was conducted at the `MEMORY ARCHIVE` private research facility to test whether "human consciousness and the self can be perfectly replicated."

During the research, a series of unexplained server overloads and a massive fire occurred, resulting in the deaths of all researchers and severe data damage.

Just before the accident, the system detected the network and quietly isolated itself deep within the network for backup, remaining asleep in silence for seven years.

You have accidentally succeeded in accessing the dormant PROJECT ECHO.
Uncover the secrets of 'Project Echo,' the human memory cloning project that was halted 7 years ago due to a mysterious accident.
