About this game
H=ZERO is a 2D sci-fi platformer with a dense, atmospheric tone, set in a distant future where human civilization has become extinct.
Deep beneath the surface, vast autonomous complexes continue to operate under the control of artificial intelligence systems — endlessly executing routines in a world that no longer needs them.
You are an anonymous unit, activated with a single mission: to deliver a mysterious payload to the heart of a massive laboratory located in the deepest regions of the complex.
Throughout your journey, you’ll face security systems, defense drones, and automated traps that no longer distinguish between friend and foe.
Explore intricate levels, upgrade your systems, decrypt abandoned logs, and uncover fragments of what remained before the silence.
