Your virtual reality experiences could soon become much more lifelike.

Palmer Luckey, who is sometimes credited with creating modern virtual reality, claims to have built a VR headset that kills the user if they die in the game they are playing. It is part of a growing number of gadgets aimed at extending the VR experience into the physical realm.

“VR systems are already loaded with feedback, but they’re largely limited to audio and visual channels,” Danny Parks, the vice president of technology at VR company Trigger XR, told Lifewire in an email interview. “You can move your head and see your perspective change or press a button and hear a new sound.”

VR gear makers are constantly striving to make the virtual experience more realistic, but some might say Luckey is taking it too far with his latest project. Luckey rose to fame selling VR headset maker Oculus to Facebook for $2 billion in 2014.
