Welcome into the official, international QuakeWorld community discord where everyone in the scene hang out, ask questions and get help. Since we revolve around Quake1, the people in here are mature and friendly!
There are several clients to play QW online, which are under active development. Most developers hang out here and anyone can chime in with suggestions!
The recommended starter package can be downloaded at https://nquake.com/ – which includes the established ezQuake client.
Welcome in!
