Xash3D FWGS Engine
Xash3D FWGS engine
Xash3D FWGS is an open-source fork and extension of the original GoldSrc-based engine (from the classic era of first-person shooters), aimed at providing compatibility with the original engine (e.g. games built on it) while extending and modernizing its capabilities. The engine supports multiple rendering backends (OpenGL, GLES, software fallback), modern platforms (desktop OSes, mobile, etc.), and updated features such as better multiplayer, voice chat, IPv6 support, improved virtual filesystem, and support for modern asset formats. For modders or fans of classic games, Xash3D FWGS offers a way to play or build games using the familiar GoldSrc workflow but with updated portability and features. Legacy mods and maps for supported games can often be used unchanged (or with minimal modifications), preserving the classic experience. At the same time, the engine’s enhancements — modern input support (gamepad, touch), modern OS compatibility, cross-platform builds. -

Crown Engine
The flexible game engine
Crown is a general-purpose and data-driven game engine, written in orthodox C++ with a minimalistic and data-oriented design philosophy in mind. Every aspect of the game is controlled through text configuration files. Before shipping, configuration files are compiled to efficient platform-specific binary blobs. Data in memory is organized to achieve the maximum performance possible on every platform. Every game asset is hot-reloadable, code included. Evaluate modifications and adjustments on-the-fly without having to reboot the game every time. Runs and looks equally well both on Linux and on Windows. Designed to be as fail-safe as possible to never lose your work if crashes should occur. Engine plus tools amounts to less than 50K LOC. Written in simple 'C-style' C++. It is easy for anyone to understand and make modifications. All the code is released under the very permissive MIT license and can be downloaded via GitHub by anyone. -

ioquake3
The ioquake3 community effort to continue supporting/developing id's
ioquake3 is a free and open source first-person shooter engine derived from the Quake 3: Arena and Quake 3: Team Arena source code, maintained as a modern baseline engine for new games and classic mods. It is designed to let players run Quake 3, its expansion Team Arena, and community mods on contemporary systems while also serving as a solid base for new projects. The engine modernizes the original codebase with a CMake build system, an SDL2 backend for cross-platform windowing and input, and OpenAL sound for better audio quality and multi-speaker setups. It adds numerous quality-of-life improvements such as VoIP support, AVI demo capture, improved console completion and history, and optional Ogg Vorbis support. ioquake3 also improves portability and maintainability by supporting x86_64 on Linux, MinGW builds on Windows, and various other operating systems, and even provides web support via Emscripten. -

Generic 3D Game Engine
A basic 3D environment with a first-person POV
Despite being more graphically advanced than my 2D game engine, it isn't as well developed. Its original name was "3DWorld" because it simulated a 3-dimensional environment -and that's pretty much all it does. You can move around, pick up a cube, and jump using typical FPS controls. I started to implement the ability to shoot but it's still incomplete. This project has been put on hold in order to focus on my 2D game engine. -
