Must also correct the path name in the Target: line. OR download Zandronum and use the DOOM.wad file from the release you have here and be able to play online too. Source: 12 months ago

The most active multiplayer Doom port is Zandronum, using the Doomseeker server browser to join games. Mac support may be a bit flaky, but I think it currently works (join the Discord for help). https://zandronum.com/ - get the software, join the discord https://doomlist.net/ - see active servers. - Source: Hacker News / over 1 year ago

That doesn´t really have anything to do with doom mods. Zandronum works similar to gzdoom. It can only play wads and pk3. You can get it here: https://zandronum.com/. Source: over 1 year ago

Cube Engine 1 and 2 touted as the smallest (in terms of file size) FPS Multiplayer game. It's also free. Unknown if the community is still booming as I have not played it in a long time. Eh while we're at it there's also Warsow but this one I know the community isn't as great as before. Source: about 1 year ago

I'd you want something a little more advanced but straight forward I highly suggest Warsow. It's a free first person arena shooter that plays very much like Quake. Source: about 2 years ago

Warsow is also quite good and very close to late 90's shooter's idea of multiplayer https://warsow.net/. - Source: Hacker News / about 3 years ago

Playing games is part of who we are as humans. Ditto for making games. From Nine Men Morris to Shattered Pixel Dungeon, Mindustry, and Warsow, people have been making and playing games for free. We don't need a games industry in order to have games. Source: about 3 years ago
