Short Summary

The KZX Engine, developed by Grand Dog Studio, is an award winning 3D game engine designed for video game development in both 2D and 3D perspectives. This free game engine is the first of its kind to be developed in the Netherlands and is available for download. Development began in 2014 and has since been continued by a small team. While the KZX Engine is currently a freeware game engine, it is licensed with proprietary software. The engine was created using the powerful C++ programming language and OpenGL for graphical rendering, while Lua serves as its standard integrated scripting language. However, it is worth noting that the KZX Engine is currently only available on the windows operating system and only supports the windows build export feature within the game editor.
