About the Game

Oneons is a short minimal, coffee-break roguelike with 12 floors of tactical combat, dangerous enemies, and useful items. Strategize your limited health and energy and strategically use items as you descend through the increasingly difficult floors. Survive. Die. Fight again.

After years of imprisonment and experimentation in a Sentinel prison, an Oneon shatters its containment pod and begins the long road to escape. Can it evade the sentinels and their minions, and rescue its fellow Oneons along the way?




  • Navigate through twelve floors filled with unique and dangerous enemies, some with powers of their own.
  • Balance careful use of combat, energy, and your unique abilities to maximize your chances of survival
  • Free other Oneons to power up in your quest for freedom
  • Permanent upgrades make it easy to win, eventually, with minimal grinding
  • Discover a story about oppression, faith, and hope

Note that Oneons is designed to be quite difficult. If you find the game too difficult, you can use the heal skill to make it easier.



Accessibility matters! Oneons contains several accessibility features, including:
  • Uses large, high-contrast images and text ideal for low-vision players
  • Uses simple, readable font for easy readability
  • Entirely playable by keyboard with fully rebindable keys
  • One-hand friendly key bindings setup by default
  • Options you can access at any time during the game


If you've never played a roguelike (dungeon crawler) game before, here are some tips and things to know to get the most out of your experience:
  • To explore, click any square that has adjacent unexplored/black squares, or click on any object.
  • Nothing happens until you take a turn. Observe carefully the effects after you move.
  • The game is difficult. Expect to die a lot. When you die, you restart from the beginning.
  • You can hover your cursor over things to see more information. Look closely at icons and their explanations.

Please note that we don't collect or store any information or data about you. Oneons connects to Steam's servers to trigger Steam achievements.
