The playable teaser for Hideo Kojima and Guillermo del Toro's Silent Hills offers a hint at the game's premise: aliens. A creepy Swedish radio broadcast outlines a world of tortured paranoia, including the phrase, "The radio drama from 75 years ago was the truth," as translated by YouTube user dimhoLten. This timeline aligns with Orson Welles' radio performance of The War of the Worlds on October 30, 1938.
Welles' broadcast of The War of the Worlds incited mass panic among the US radio audience, as it was presented as a series of news bulletins describing a live alien invasion, which many listeners took at face value. The radio drama was based on HG Wells' 1898 novel The War of the Worlds.
