Players of the video game Hello Neighbor have to investigate the mysterious guy next door, Mr Peterson, sneaking into his basement to uncover a dark secret.
The survival horror game, launched in 2017, has gained a cult following and such is its popularity that its developer, TinyBuild, was emboldened to go public this year, listing its shares at 169p on AIM in March to raise £154.4 million at a valuation of £340 million.
Since then, they have risen 49 per cent to 251p, giving TinyBuild a valuation of £509 million. Not bad for a business that made $37.6 million (£27.2 million) in sales last year.
The Seattle-based company is a small player in a booming industry expected to be worth $200 billion by 2023. Founded
