Leo Vance dies for the hundredth time in the ruined world of 2047, his body torn apart by a powerful Chitter Alpha. For ten years he has survived in a nightmare where alien creatures called Chitters overrun Earth. Death has become familiar to him, but this time something unexpected happens. Instead of waking up days or weeks in the past like before, his consciousness is thrown ten full years back—to October 31st, 2037, the exact moment the mysterious event known as the Veilfall began.
Leo keeps the memories, experience, and survival instincts he gained from a decade of brutal fighting. However, his body is once again that of his younger self, weaker and untrained. While the world around him still looks normal, he knows that within hours society will collapse as dimensional rifts tear open the sky and release the first wave of Chitters.
This time, Leo discovers something strange. Any firearm he touches never runs out of ammunition. It is an impossible power in a world where survival usually depends on rare weapons and limited resources. The bullets may be infinite, but Leo’s stamina, sanity, and humanity are not.
As the Veil changes reality, a mysterious system appears. Humans can gain experience by killing Chitters, allowing them to Level Up and awaken abilities connected to something called Aether. Victories produce Treasure Orbs—glowing spheres that contain weapons, technique manuals, enhancement serums, and other powerful items.
Armed with his knowledge of the future and his strange infinite-ammo ability, Leo sets out to change the fate of humanity. He must survive the first days of chaos, guide key allies, and stop the disasters he once witnessed. But altering the timeline may demand terrible choices, and Leo must decide how much of his humanity he is willing to sacrifice to save the world.
