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. -

OGRE
scene-oriented, flexible 3D engine (C++, Python, C#, Java)
OGRE (Object-Oriented Graphics Rendering Engine) is a scene-oriented, flexible 3D engine written in C++ designed to make it easier and more intuitive for developers to produce games and demos utilizing 3D hardware. The class library abstracts all the details of using the underlying system libraries like Direct3D and OpenGL and provides an interface based on world objects and other intuitive classes. We consider the results of our GL3Plus RenderSystem as the gold standard. The respective shaders are generated by the RTSS component with per-pixel specular lighting. Therefore the legacy render systems naturally have differences due to the use of fixed-function. However, when rendering diffuse surface both produce pixel-perfect results. Simple, easy to use OO interface designed to minimise the effort required to render 3D scenes, and to be independent of 3D implementation i.e. Direct3D/OpenGL. -

Luanti
Voxel game-creation platform with easy modding and game creation
Luanti, originally known as Minetest, is a free, open-source voxel game engine and platform designed to let players, modders, and developers build and play diverse sandbox-style 3D worlds. Written in C++ for core performance and Lua for scripting, Luanti runs on multiple operating systems (Windows, macOS, Linux, BSD variants and even Android), making it highly accessible and cross-platform. Rather than being a single game, Luanti is meant as an engine and toolkit: individual “games” are actually collections of mods — written in Lua — that define terrain, items, NPCs, mechanics, and rules. This modular design enables rich customization and community-driven content: users can install new games, mods, and texture packs via a built-in content browser that draws from a central repository (ContentDB). Luanti supports both single-player and multiplayer via servers; players can host their own or join publicly listed ones, with server-side mods being applied automatically. -

Redot Engine
Multi-platform 2D and 3D game engine
Redot Engine is an open-source game engine that aims to provide a flexible foundation for building games — likely offering a modern, modular structure so developers can compose only the systems they need (rendering, physics, input, scripting, etc.). It is built to give a base framework rather than a full “batteries-included” engine, which makes it suitable for developers who prefer minimalism, want complete control over architecture, or desire to build custom workflows. Because it’s open-source, Redot-Engine is potentially community-driven, allowing anyone to inspect, extend, or customize core functionalities. Its modularity and open nature make it attractive for indie developers or hobbyists who want to avoid heavyweight engines with lots of built-in assumptions. Even if the engine may not yet rival more mature engines in features or polish, its openness and design philosophy can offer an appealing balance between simplicity and flexibility. -

LiquidFun
2D physics engine for games
LiquidFun is a 2D rigid-body and fluid simulation C++ library for games based upon Box2D. It provides support for procedural animation of physical bodies to make objects move and interact in realistic ways. You can write LiquidFun code in C++, Java, or JavaScript. LiquidFun is an extension of Box2D. It adds a particle based fluid and soft body simulation to the rigid body functionality of Box2D. LiquidFun can be built for many different systems, including Android, iOS, Windows, OS X, Linux, and JavaScript. For applications on Google Play that integrate this tool, usage is tracked. This tracking is done automatically using the embedded version string (b2_liquidFunVersionString), and helps us continue to optimize it. Since this is open source, you are free to remove the version string but we would appreciate if you would leave it in. -

Urho3D
Urho3D Game engine
Urho3D is a game engine made by developers, for developers. The code is clean and well-commented. Urho3D is free and will always be free. There is no hidden royalties. It is IDE-agnostic and has no vendor lock-in. Urho3D runs on Windows, Linux, macOS/iOS/tvOS, Android, and even on Raspberry Pi. It also runs on your browsers. You need an installed Urho3D library for the desired target platform to proceed. Although the Urho3D build system also supports linking the Urho3D library directly from its build tree, this quick start section will not be discussing it here. Assuming you have been following along from the previous section, execute the following commands to create a new UrhoApp project, and then build it. The build artifacts from DBE can be found in the usual location as the conventional (non-dockerized) build environment. In fact the build artifacts from DBE should function and work as if they are built using the conventional way too. -
