"When the zombie uprising came, I was thankful for two things. One: I was carrying a big gun. Two: My virtual reality headset didn't have me tethered to a uselessly short cable," said a writer for Cnet that tried playing the VR game called Outbreak Origins. Free-roaming games have been historically popular, and they are even cooler in virtual reality. Describing what it was like to be in the game she said, "For instance, in my new virtual world, I was running through a 3D hellscape of post-apocalyptic ruins, pwning zombies and fighting for survival. In reality, I was with three nerdy colleagues in the bowels of the MGM Grand, covered in panic sweat and shouting obscenities as we ran around a 2,000-square-foot (185-square-meter) black box room."
