The world didn't end with a bang, but with a blue screen.
For Alex Mercer, life revolved around conquering digital realms in the MMORPG *Aethelgard's Legacy*. But when reality itself glitches, overlaying the familiar world with a terrifyingly real game interface – complete with HP, levels, and skills – the rules suddenly change.
Overnight, the System arrives. Power grids fail. Monstrous creatures pour from shimmering portals. Impossible towers pierce the sky, and dungeons yawn open in city parks. Chaos reigns as society collapses, and the only status that matters is ‘Alive’.
While others panic, Alex’s gamer instincts give him a razor-thin edge in understanding the new world's brutal logic. But this is no game. Death is permanent, choices lock you onto irreversible paths, and every level gained is paid for in blood and terror. Teaming up with other desperate survivors, Alex must fight not only grotesque beasts from nightmare but also the darkness within humanity itself.
Why has the System chosen Earth? What are the colossal towers and mysterious dungeons hiding? And can a gamer truly level up fast enough to survive when the world itself has become the ultimate, unwinnable raid? In a world unbound, the only way forward is up... if you can survive the climb.
