AI-made browser game Saltline resurfaces in Chinese chat groups as a 'domestic AAA' title
Anthropic engineer Felix Rieseberg released the game on 10 November; a 1.4 MB copy circulating as 《几猫》 kept his code but removed his name
Key takeaways
- Anthropic engineer Felix Rieseberg published Saltline, a playable browser game, on 10 November 2026.
- Rieseberg said the models, sound and textures were generated by Claude Fable 5.2 in about eight hours.
- He put the cost at about $550, based on roughly 445 million input tokens and 2.7 million output tokens.
- A 1.4 MB HTML file spread through Chinese group chats as 《几猫》, a self-described domestic AAA game.
- The file kept Saltline's name in its source code but removed Rieseberg's credit, according to YYSTV.
A browser game, then a copy
On the morning of 10 November 2026, Felix Rieseberg posted a playable link to a browser game called Saltline. Rieseberg, whose LinkedIn profile lists him as an engineer on Anthropic's technical team, said the game's models, sound effects and textures were generated from scratch by Claude Fable 5.2.
He said the work took about eight hours and used roughly 445 million input tokens and 2.7 million output tokens. At API prices, he put the cost at about $550, or about 3,668.69 yuan.
Within a day, a 1.4 MB HTML file was moving through Chinese group chats under the name 《几猫》. Players who opened it found a working first-person shooter demo, according to the Chinese games outlet YYSTV, which traced the earliest public record to the morning of 10 November.
What the file claimed
The message that travelled with the file, and the project notes inside it, described 《几猫》 as a self-developed domestic AAA game built on Claude Fable 5.2. The text used 'domestic AAA' repeatedly, YYSTV reported, and ended with a request for feedback.
No developer name or contact details appeared anywhere in the file. YYSTV said the copy was a lightly localised version of Saltline: the original's name was still in the source code, but Rieseberg's credit had been removed.
YYSTV reported that the file fooled some players at first. It lost credibility once it spread beyond its original circles, as users compared it with Saltline and posted their findings.
The wider pattern
YYSTV said the episode fits a broader trend of overseas open-source AI projects being relabelled for Chinese audiences, sometimes to make money from the information gap. The outlet argued that AI lowers the cost of this kind of copying, because a project already produced by AI can be reworked by AI without the copier understanding the underlying development.
YYSTV did not name the people behind 《几猫》 or say whether anyone profited from it. The authenticity of a group-chat screenshot the outlet reproduced could not be verified, it said.
