Our take on HYDROGEN

The defining combat twist is the parry: a successful block reflects the exact attack back at its source.

What is HYDROGEN?

Hydrogen is an action roguelite set in a post-apocalyptic science-fiction world, where a mercenary fights to rescue humanity from impending doom.

Each run moves through procedurally generated instances with changing challenges and random items. The mercenary gains perks to develop abilities and customize a playstyle. Combat includes physical damage and elemental attacks: fire and acid deal damage over time, electric attacks can hit multiple targets, frost stuns enemies, and void knocks them back. A successful parry reflects the enemy’s attack, while dashing makes the character invulnerable to damage for the duration of the dash.

How HYDROGEN plays
