Aetheria – Free Online .io Game

An online fantasy RPG where you build a hero, explore mines, forests and dungeons, fight monsters and bosses, collect rare equipment and pets, complete quests and join clans. Progress through levels and Rebirth tiers as you go. Note: this game asks you to sign in before playing.

Which device? We do not hold a control list for Aetheria yet, so we cannot tell you what it expects. Open it and see — and if it does not respond to taps, try it on a computer. The full-screen link above gives it the whole screen either way.

1. Create your hero, then explore the mines, forests and dungeons.
2. Fight monsters and bosses to collect equipment, pets and quest rewards.
3. Push through levels and Rebirth tiers, and join a clan if you want company.

Controls — general guide

• Mouse or touch: click, or tap if the game accepts it. Some games here are built for a touch screen and some want a keyboard — the note above says which this one is.
• Keyboard (if the game uses it): arrow keys or WASD to move, and the space bar to jump or act.
• Full screen: use the “Play full screen” button above for a bigger view.

• Read the steps above before your first run — Aetheria documents 3 of them, and most early losses are just not knowing the rule.
• Use Play full screen if anything feels cramped — it hands the game the whole window, which matters most on a laptop.
• Nothing saves to SlowDen. Closing the tab ends the run, so finish a level before you leave.
