WARNING: Some readers may find this video distressing
The zombies, monsters and demonic-looking characters at the New Zealand haunted attraction Spookers are rapidly gaining a following around the world.
Spookers posted a video to Facebook on Friday showing the company's "scarers" creeping, lunging and bursting from doorways in a derelict hallway of the Haunted House at its premises in Karaka.
The video has since been viewed more than 50 million times, after viewers were encouraged to "tag someone who couldn't make it to the end of the hallway".
The gruesome theme park is set at Kingseat, an abandoned psychiatric hospital in South Auckland. It is staffed by young actors who specialise in scaring visitors.
