Phantom Smog Demo

About this game

A toxic gas is spreading across the world, poisoning everything in its path. While humanity collapses, you are the only one immune — and the last hope to stop the organization behind this catastrophe.

This is a fast-paced roguelike metroidvania that blends intense combat with exploration across handcrafted, interconnected maps. Every area is designed to flow seamlessly, encouraging discovery, backtracking, and mastery of movement and combat.

The demo features 2 distinct maps and a powerful boss, giving you a solid taste of the game’s core mechanics, atmosphere, and progression systems.

Throughout your run, you’ll unlock and choose permanent upgrades that shape your playstyle, allowing you to evolve your abilities and adapt to increasingly dangerous threats.

With a strong retrowave and cyberpunk aesthetic, the game delivers frantic action, a dark and oppressive atmosphere, and rewarding progression in a desperate fight against a poisoned world.

Can you survive the gas — and stop what’s coming next?

Phantom Smog Demo

In a future suffocated by VX-Nebel, the megacorporation NOVA ATMOS controls every breath of the city. You are Kael, the only one immune to the gas — and therefore the only real threat. Track down and eliminate the leaders behind the conspiracy.
