Run3 is released as an open-source game engine!
The source code is on C++ written in Visual Studio 2003. Unfortunately, it is a very old compiler. The development of Run3, as the development of a first game on Run3 -The Long Way, lasted for years.
Although, with documentation, building Run3 is not a difficult task.
With a source code, you can make some mods for The Long Way game.
API of Lua scripts will be added soon.
Wiki repository will be extended and updated.
The near future of engine is being decided. It will depend on a solution, what engine I will use for the future of "The Long Way".
