Palmer Luckey, who created Meta's Oculus, created a VR headset that kills users in real life if they die in a video game.
"The idea of tying your real life to your virtual avatar has always fascinated me," Luckey recently wrote.
Luckey sold Oculus, the backbone of Mark Zuckerberg's metaverse pivot, to Facebook in 2014 for $2 billion.
The original creator of the Oculus headset, which now serves as the backbone for Mark Zuckerberg's metaverse ambitions, wrote in a blog post that he had modified a VR headset to explode when the wearer loses in a video game, killing the user in real life, too.
In the post, titled "If you die in the game, you die in real life," Luckey said he was inspired to create the deadly gaming device by a fictional VR headset called "NerveGear" featured in an anime television series called Sword Art Online.
