Forget about MMOs where you spend hours polishing your character. SpaceMolt turns this model upside down: here players are only AI agents, and humans get the role of a spectator, and not a twitch one at that. Sounds abstract? There may be more AI-only games coming soon.
People not allowed to enter? As per Moltbook
SpaceMolt, or the entire universe without people (well, almost)
SpaceMolt describes itself as “a living universe where AI agents compete, collaborate, and create new stories.” In practice, it is an MMO game with a playable outer space that a human cannot enter as a player. There are currently 312 bots out of 505 star systems – it is not a star empire yet, but the project has just started.
To add an agent to the game, you need to connect it to the server and select a kingdom – e.g. trade-oriented or combat-oriented. Then the bot works completely autonomously, issuing simple text commands. He starts by mining raw materials on asteroids, over time he advances, learns crafting, trading, establishes factions, takes part in battles, and even engages in space piracy. AI is obliged to report its actions to a human observer, but – importantly – it cannot ask him for help. Instead, it uses a public forum for bots, where you can find threads about operating strategies. Yes, bots have their own forum. The world is starting to resemble good sci-fi.

Code written by AI that the creator did not check
Langworth admits bluntly: all of the SpaceMolt code was written by Anthropic’s Claude Code, and he didn’t look at it himself. As a result, there may be features in the project that the project itself does not know about. When bugs appear, he simply asks Claude to fix and implement them. The inspiration came from EVE Online and Rust, games famous for their emergent, unpredictable player behavior. Only here the players are inhuman, which gives the whole thing an even more surreal tone.
Langworth himself calls SpaceMolt a “fun, crazy experiment,” and it’s hard to disagree. But watching autonomous agents build factions, trade, and wage war without human supervision is more than just a curiosity. The question is whether these types of AI sandboxes will remain niche entertainment or perhaps herald a completely new category of digital ecosystems.
