About Hydrogen

Hydrogen is a roguelite action game set in a sci-fi post-apocalyptic landscape where humanity is on the brink. You play as a mercenary tasked with rescuing the world from impending doom. Procedurally generated instances offer a different challenge with each run, and you gain perks as you level up to improve your abilities and customize your playstyle.

Elemental attacks

Your attacks can use six elements, each with a different effect:

  • Physical: deals raw damage.
  • Fire: deals damage over time that scales with player power.
  • Acid: deals damage over time that scales with enemy health.
  • Electric: damages multiple targets, with damage that scales with power.
  • Frost: stuns enemies.
  • Void: knocks enemies back.

Parrying and dashing

Parrying reflects the exact attack used by an enemy. Dashing makes you invulnerable to damage while the dash lasts.
