About
Free Allegiance is an open-source project built with Visual Studio and the Microsoft DirectX SDK. The codebase is split into a client (WinTrek), a game server (FedSrv), a lobby, and a game-logic library (IGC), with supporting sub-projects for 3D graphics, effects, sound, and networking.
Getting started
Getting it running currently means compiling from source with Visual Studio Community and the Microsoft DirectX SDK — no separate pre-built release download is mentioned in the project material itself.
