A studio called Timeline opened a Steam page on 26 October for Three-Body: Eve of Judgment (三体：审判前夜), a narrative adventure that carries an official Three-Body universe licence. In the page’s AI content disclosure, the studio says that all of the game’s video, including cutscenes and story sequences, was generated by AI (Steam store page).
The listing names Timeline as both developer and publisher. The game is for Windows only and is marked “coming soon”, with no price or release date. Simplified Chinese is the only language listed, with interface, full audio and subtitles. Timeline promises more than 300 minutes of play, several story branches and multiple endings. Its Steam tags include full-motion video, interactive fiction and QTE.
A rescue mission before Operation Guzheng
The game is set just before Operation Guzheng, the attack on the Earth-Trisolaris Organization (ETO) in Liu Cixin’s novel The Three-Body Problem. The player is Chen Anjiu, a former special forces soldier. He boards the ETO ship Judgment Day under a false identity to rescue someone. According to the store text, the factions on board want different things, so the player has to hide who they are, read conversations, gather clues and use items to get past obstacles.
Liu’s novel was serialised in 2006 and published as a book in 2008. Ken Liu’s English translation came out in 2014 and won the Hugo Award for Best Novel in 2015 (Wikipedia). That translation is where English readers know the operation and the ETO from.
Chinese and Japanese outlets call it an “AI interactive film”
IT Home reported the Steam page on 26 October. Its headline calls the game the first AI interactive film game licensed by Three-Body Universe, and it says the first trailer is already out. The report does not explain how the licence was arranged or which parts of production used AI beyond the label. The next morning, Japan’s Denfaminicogamer covered the page, noting that the game supports only Simplified Chinese for now and that the trailer is on bilibili.
We found no information about Timeline outside the store page, and no statement from the licence holder. For now, the Steam page is the only place the studio has described how the game was made, in its AI content disclosure. It does not say whether the script, voices or game logic also involved AI.
An English screenshot, but no English listing
At least one of the official Steam screenshots shows English dialogue options and an English subtitle (“Mr. Chen… You used to be in the military, didn’t you?”), so an English text version appears to exist in some form. The store still lists Simplified Chinese as the only supported language, and Timeline has not announced an English release. The Steam page can be wishlisted now. A release date, price or added languages would be the next concrete news.
