What this is

📺 A text game you play by talking to Grok. You work the great unsolved case of American broadcasting: the night in 1987 when someone in a mask took over two Chicago television stations. The stations, the times, the engineers' own words and the FCC investigator's account are real; your investigators are invented. You get a numbered menu every turn, and you can always type something of your own instead.

Sunday, 22 November 1987. A sports report on Channel 9 goes black. Two hours later Doctor Who stops dead on Channel 11, and something else is on your television for ninety seconds.

Work it as an FCC field engineer, a station engineer, a reporter, a hamfest regular or a tape collector, chasing evidence that really exists:

Type "fact" and the game breaks character: what the record holds, where two FCC spokesmen gave different answers the same day, and what was invented. It never names a private individual — nobody ever has.

Every scene quietly composes a full media set you can picture or save, and saved scenes become AI-generated reenactment films at momatio.
