This repository contains the original source code for a classic real-time strategy game, serving as a legacy game engine implementation for managing units, maps, and combat mechanics in a military strategy setting. It functions as a real-time strategy game source code archive intended for preservation and technical study. The codebase acts as a game modification base, allowing developers to create custom content and modifications using the original source. It provides a foundation for retro game modding and software archeology to analyze how historical game mechanics were programmed. The pro

Mindustry is a cross-platform game engine and factory automation simulation that combines resource management with tower defense strategy. Players construct complex supply chains and automated networks to process materials while building defensive structures to protect a core from waves of hostile mechanical forces. The project utilizes a deterministic lockstep networking model to ensure simulation consistency across desktop and mobile devices. It is built on an entity-component-system architecture and a tile-based grid simulation, allowing for the efficient management of thousands of active

Unofficial open-source OpenGL/SDL2 reimplementation of Sid Meier's Alpha Centauri ( Alien Crossfire ).

Cataclysm-DDA is an open-world survival game and turn-based roguelike set in a post-apocalyptic world. It functions as a simulation where players manage resources, engage in combat, and handle character progression in an environment where time only advances when the player takes an action. The project includes a procedural world generator that creates randomized, persistent environments and city layouts, ensuring unique maps for every new game session. The simulation covers tactical movement and resource management through turn-based strategy gameplay. It also provides options for personali

CorsixTH is an open-source game clone and hospital management simulation game. It functions as a reproduction of a classic management title where players coordinate staff and treat patients to manage a medical facility. The project includes a level editor tool for designing original maps and campaigns. It also features a customizable input system that allows users to map game hotkeys and personalize control schemes. The simulation supports game localization to translate interface text and dialogue into multiple languages.
