It doesn't seem too difficult at first as you watch other players struggle to walk out on the plank. "How hard can it be, it's just a piece of wood on the ground". After you put on the headset though, your reality is changed and you can't turn back.
"Don’t miss the Plank! Easily the most realistic. You walk the plank out over a city skyline. They simulate the wind with an industrial fan, your toes at times dangling off the edge of the building and yes, you can fall to your death. Absolutely terrifying but I found it personally rewarding as someone with a fear of heights." - Anthony
