OpenArena

About

Quake III Arena is a 1999 multiplayer-focused first-person shooter by id Software, whose single-player mode is played against bots. This repository is the OpenArena engine, a fork of ioquake3 with OpenArena-specific client and server changes, built as a standalone game that needs no Quake III CD key. It keeps its own renderer, openarena1, separate from the untouched ioquake3 renderers, so either can be chosen when the game starts.

How it differs from the original

Its renderer adds widescreen support, reworked lens flares, and extra post-processing effects, including one that imitates a popular 1996 3D card. It also has an optional slowdown mode that simulates a typical 1998 computer.

Getting started

It builds as a standard ioquake3 project; on Debian or Ubuntu, the easiest route is to install ioquake3's build dependencies and run make. The renderer is chosen at launch, and ioquake3's opengl1 renderer is a fallback if OpenArena's own renderer gives trouble.

Status & roadmap

• The README notes initial testing only on Debian and Windows, and asks for help testing other platforms and the SDL2 branch.
