Open-source alternatives to Wolf3d

Quake III Arena is a first-person shooter game engine and arena combat simulator. It consists of the original C++ game source code for a cross-platform 3D game designed to run on Windows, Linux, and Mac. The project provides the source code necessary to render a first-person shooter experience, focusing on player-versus-player battles in closed 3D environments. It serves as a resource for legacy game preservation and the study of early 3D game engine construction. The engine incorporates spatial partitioning, client-side prediction, and state synchronization to manage multiplayer networking

This repository contains the C++ game source code for a single-player first-person shooter action game. It is a software implementation of the Id Tech 4 engine, designed for 3D rendering with a focus on real-time unified lighting and geometry. The project enables the modification of core engine logic and rendering systems. It serves as a resource for classic game engine modification, first-person shooter development, and retro game preservation. The engine utilizes a unified shader pipeline and stencil shadow volumes for lighting effects, alongside BSP tree spatial partitioning for visibilit
