In 2020, Chinese game developer and Bilibili content creator Chen Jiacheng hosted a livestream where he challenged himself to code a functioning zombie survival game in just 30 minutes using Unreal Engine.

While the initial 30-minute challenge failed to yield a completed project, Chen spent another 3 days improving it and released it for his followers. As popularity grew, he dedicated another week to it.

In September 2021, Chen paid the $100 developer registration fee out of pocket to put the game on Steam. He did this simply because the game had grown too popular for standard cloud-sharing drives, which were bottlenecking download speeds for his community.
