    ioquake3

    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.

    Crown Engine

    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.

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.

    ReBOOM

    ReBOOM

    Conservative port of BOOM 2.02 to modern systems.

    ReBOOM is a direct port of BOOM 2.02 to SDL2 aiming to be as close to the original as possible while adding Quality of Life features to it, such as always on stats. ReBOOM is demo compatible with BOOM 2.02. Please note, that this is essentially BOOM 2.02 compatible, it is NOT compatible with many wads 'claiming' to be Boom-compatible. Many of these modern Boom wads are in-fact only PRBoom-compatible and are not classed as Boom-compatible by myself or by historical Boom. It is pure fantasy. ReBOOM was primarily developed for GNU/Linux systems.
