In 2077, a "Red Mist Catastrophe" suddenly occurred around the world. Cities were shrouded in strange red mist, mutated creatures were rampant, and human civilization was on the verge of collapse. At the same time, a mysterious game called "Doomsday Survival" suddenly arrives, and all survivors are forcibly bound. The behavior in the game is closely connected with reality, and survival and elimination are only a matter of thoughts. The male protagonist Lin Chen awakens to the "Twin Interface". In addition to the basic game interface that all survivors have, it also has an independent "backtracking" interface, which can consume a small amount of survival points to preview upcoming key events for 10 seconds and backtrack to the selected node (the number of uses per day is limited, and more functions are unlocked as the level increases).
