Back to 2017, I and my team at Horus Entertainment (https://horusent.com) develop a battle royale game Bullet Strike. This was even prior to the releases of PUBGM or Freefire by Tecen and Garena.
We had a huge number of players for the alpha version with more than 10,000 CCU. Unfortunately, we are unable to compete with the major players in the industry due to limited funding and development resources, leading us to cancel the project prior to the beta launch. But I had the idea for time-as-currency concept at that time, mostly inspired by the In Time movie (2011).
After the rise of NFT games in late 2021, I aimed to merge blockchain technology with a high-quality battle royale game. And then MetaDOS (https://metados.com) was born.
