The Story of the Untold Engine

Hi, my name is Harold Serrano. The story of the Untold Engine began on a particular morning in 2013. Unknowingly, I had felt dormant in my life. I decided to hire a physical trainer, eat healthy and run 6 miles a day. In less than a year I went from 210 lbs to 150 lbs.

I also decided to do something beyond my intellectual abilities. Something that would require determination and commitment. Something that would shake me from within. Thus, I decided to do develop a Game Engine from scratch.

On July 21, 2016, around 2:00 am, I was able to create what I thought was unattainable; I had created a 3D Game Engine from scratch.

It took three years, about 1,095 days, approximately 15,330 hours of work. And against all the odds, I did it. I developed what many considered impossible.

However, it took an additional two years to develop a working, fully functional 3D game engine that could be used by the public.

On July 28, 2018, I released the game engine to the public.
