Dangerous Rays is using a in-house game engine, called “DR Engine” for now.
Programmed entirely in C++ and for the PC platform, DR Engine is made with flexibility, performance and modding support in mind. it's using the latest C++ standards, compilers and tools for max execution speed. DR Engine is in constant evolution and is updated each months with new features and optimizations. DR Engine is meant to be used for several years to serve Dangerous Rays visuals and gameplay.

One of the main key feature of the engine is it's extended modding capabilities. Allowing regular or total conversion mods to be made for Dangerous Rays.

This game engine is coded by OldSnake, the lead developer of Dangerous Rays. The engine is originally based on a very old version of Urho3D engine. At the present day, a very large part of the original Urho3D code has been rewritten.
The engine is not available for licensing.
