Osta Afallon PC

A singleplayer MMO. Explore a large open world, run dungeons, gear up, and take on challenging content with NPC Adventurers that play alongside you like real players. If you've ever wanted the feel of an MMO but without the need for other people, this is the game for you.

Large open world
Explore a large open world filled with quests, dungeons, gear to chase, and enemies around every corner. The controls will feel instantly familiar if you've played any MMO before. Click to target, tab targeting, move your camera with the mouse. No learning curve, just jump in and play.

Play your way
How you play is up to you. Stick with traditional MMORPG controls, or switch to Action RPG controls and aim your abilities yourself. There is no right way to play, it is all up to you.

Simulated players
The world isn't empty. NPCs called Adventurers roam the land doing everything a real player would. They quest, group up, fight enemies, loot gear, visit vendors, and equip upgrades. You can inspect their gear, invite them into your party, and take on dungeons together. They'll tank, heal, roll on loot, and even fail boss mechanics sometimes. They make the world feel alive without needing a single other person online.

Dungeons
Dungeons come with the Corruption+ system, a scaling challenge mode with a timer, increasing difficulty, and better loot the higher you push. If you want to test your build and your skill, you can keep climbing as high as you can handle.

Make the world yours
You decide how the world plays. When you create a new character you can change how strong enemies and allies are, and set your own multipliers for drop rate and XP gain. Build the exact experience that fits you, whether you want a relaxed run or a punishing challenge.

Early Access
This is a solo project built by one person and actively developed during Early Access. New content, features, and improvements are being added regularly.
