XWIS

XWIS (short for eXtended Westwood Internet Server) is a community-run multiplayer service which allows people to play Tiberian Dawn, Red Alert 1, Tiberian Sun, Firestorm, Red Alert 2, Yuri's Revenge, Renegade and Dune 2000 online. It is an imitation of the original Westwood Online server and was shifted to community control by Electronic Arts in 2005. It has been sponsored by the German branch of Electronic Arts since.

Overview
The server mimics most of Westwood Online features and requires no third party tool to connect to XWIS. An account needs to be created in the XWIS Control Panel, after which nicknames need to be formed and assigned to serial keys. The exception is Tiberian Sun, which users can play without a serial key (due to the game's freeware nature), but ranked a key is still required for ranked play.
