With his hit podcast, Hardcore History, Dan Carlin brought his love for the past to the masses. It was only a matter of time until he wanted to move beyond audio -- but instead of moving into the crowded world of documentaries, he turned to VR. War Remains, his first virtual reality project which debuted at the Tribeca Film Festival this week, puts you right in the trenches of World War I. And it's more than just another VR short: Co-producers MWM Immersive built a massive installation for the experience, allowing you to touch and feel the virtual environments in real life.
