The Roblox Death Sound Syndrome (also known as "Roblox Death Tone" or "Phantom Forces Suicides") was a peak in suicides and illness of children between the ages of 7-69 shortly after the release of Roblox Classic and Roblox Season Pass Edition in Merica, back in February 27th, 2006.
Rumors say that these suicides and illness only occurred after the children playing the game played Phantom Forces, which death sound had extremely high frequencies, that studies showed that only children and young teens can hear, since their ears are more sensitive.
Due to the Roblox Death Tone, at least two-hundred children supposedly committed suicide, and many more developed illnesses and afflictions. The children who committed suicide usually did so by hanging or jumping from heights. Those who did not acted irrationally complained of severe headaches after listening to Phantom Forces Death Sound.
Although the Death Sound now sounds differently depending on the version, this mass hysteria was caused by the first Roblox game released. After the Death Tone Tone incident, the programmers had fixed Phantom Forces Death Tone to be at a lower frequency, and since children were no longer affected by it.
One video appeared in 20XX using ”special software" to analyze the audio of Phantom Forces sounds. When played, the software created images of the Steve near the end of the audio. This raised a controversy, since Steve didn't appear until Minecraft.
There is also the said Beta Version of Phantom Forces.
It is said that the Beta Version of Phantom Forces was released to some kids to test the games. This is the video of the Beta Version of Phantom Forces: https://www.youtube.com/watch?v=H-fWXSAO76Y
