The neon lights in New York suddenly changed on Christmas Eve, the snow and wind in Altai suddenly stopped, and a "game" across the hemisphere started without warning.
Dozens of countries, including the United States, China, and Russia, were involved in the unknown copy in the announcement of the mechanical sound. The memory of reality was completely erased, and the grudges and bonds of the past were all blank.
Crazy Los Angeles, tombstones deep in the snowfields, the alternate dimension behind the revolving door, companions who suddenly disappeared...
They were forced to struggle to survive in layers of dungeons such as "Los Angeles", "Snowfield" and "Urban Fantasy". They relied on instinctive trust and suspicion to form a team, and gradually pieced together the broken clues during puzzle solving and confrontation.
As the memory fragments gradually recover as the mission progresses, old and new grudges between countries begin to intertwine, and the shadows hidden behind the system become increasingly clear. Those names that have long since disappeared in the long history are watching this "bond test" coldly through the screen.
When the door to the final copy opened, they were shocked to realize that this game was never a random selection, but an ultimate trial against "existence" itself.
The disappeared countries have returned by subverting the rules, and those who are alive must make choices related to the survival of civilization between forgetting and remembering.
Intention: Memories
