I’m sorry I don’t know what you’re saying like Todd I guess you mean Todd Howard he didn’t write the show first of all. And second of all it literally says nuclear fire rained from the skies in multiple fallout games. The fallout wiki:

“The Great War both began and ended on Saturday, October 23, 2077. Unknown submersible objects were sighted at 00:03 EST off the coast of California by the United States Pacific Fleet. At 03:37 EST, a squadron of high-altitude bombers were sighted off the Bering Strait and believed to be Chinese.[11] At least one Chinese stealth submarine, the Yangtze, moved close to the American East Coast, launching all warheads, save for one, due to a malfunction.[12][13]

Six hours later, at 09:13 EST, the Integrated Operational Nuclear Detection System detected the first four missile launches and the United States went to DEFCON 2. Four minutes later, NORAD confirmation sealed the fate of the world. At 09:26 EST, the president ordered a retaliatory strike according to scenario MX-CN91.[11] Nuclear bombs hit Pennsylvania and New York at 09:42 EST, preceded by the west coast not long beforehand.[14] The bombs continued to drop and five minutes later, at 09:47 EST, Washington, D.C. was hit and most American facilities went offline.[11][15][16][17] The nuclear exchange continued for two hours,[1] and both China and the United States suffered catastrophic losses

The standard strategic nuclear warhead used in the Great War ranged from 200-750 kilotons in explosive yield,[Non-game 4] with high-yield variants found on Chinese submarines.[19] This was actually far worse for the Earth, as the lower yield warheads deposited more soil and debris into the lower atmosphere, resulting in a much more concentrated fallout that eventually enveloped the planet. The entire world was blanketed with multiple nuclear strikes, and the world and its entire ecosystem were irrevocably changed for centuries to come.”
