Hedra is a 3D open-world RPG with procedurally generated worlds, quests, skills, and multiple classes that was created from scratch by its developer starting in high school at age 15. The project evolved into a full game engine written in C++ with approximately 100,000 lines of code, featuring advanced graphics rendering capabilities, modding support, and availability on Linux and Windows. The game includes gameplay elements like fishing, crafting, trading, companions, and a skill tree system alongside engine features like dynamic shaders, particle systems, and Steam integration.
