## **Game engine**
Prometheus engine developed based on COCOS. Cocos 2D-X, Cocos Studio, Cocos Code IDE, and additional frameworks and tools are integrated with Cocos to give developers a complete set of game development options. We chose Cocos as our development engine since it has proven to be one of the most reliable engines in mobile game development over the last decade. It provides trial-play technology for all three terminals (PC, mobile and web).
