Bulgarian Metro: Descent into Ash

Martin, an ordinary high school student, awakens in a nightmarish Bulgarian subway system, a subterranean labyrinth where radiation has twisted humanity and the surface is a death trap. Reborn in this post-apocalyptic Metro, each station is a fiefdom controlled by warring factions, desperately clinging to survival. He possesses the unique 'Tree Skill System,' a latent power that branches into physical, mechanical, and metaphysical abilities, growing stronger with every desperate choice. Martin's immediate struggle is survival, forced to navigate the treacherous political landscape of the underground. He must choose an allegiance, or risk becoming prey to both ruthless factions and the evolving horrors lurking in the dark tunnels. But the true terror lies in the constant, agonizing decision: embrace the brutal safety of the Metro, or dare to venture to the mutant-infested surface, where a forgotten truth might be buried alongside the ruins of the world. His power might be his salvation, or his ultimate curse.
