When a fractured distress call cuts through the Voidstream, Mika is already battling the slow death of his failing ship. Answering it may mean salvation… or doom. Drifting in the cold expanse, a derelict freighter looms — silent, scarred, and spilling fragments of its story in rust and blood. Inside its shadowed corridors, Mika and his companion step into a waking nightmare: walls slick with old violence, a strange cargo that hums with hidden promise, and something alive… something hunting. When a catastrophic rupture floods the decks, survival becomes a race through half-submerged chambers as the creature stalks them in the dark water. With his young ally tethered to the controls of their crippled craft, guiding them from afar, Mika must gamble everything — not only to live, but to seize the freighter's cargo and escape before the void claims them both. Black Signal is a tense, atmospheric chapter in the Mikanical series — a blend of sci-fi grit, survival horror, and desperate ingenuity where every breath counts and every shadow has teeth.
