You need the original DOOM2.WAD file. This is required and not included with Zandronum. You must own a copy of Doom II (e.g., from Steam or GOG).
After installing Doom II, look for DOOM2.WAD in your game folder (often in C:\Program Files (x86)\Steam\steamapps\common\Doom 2\base\ on Windows).
Copy DOOM2.WAD into your Zandronum folder.
(Optional) Download DoomSeeker:
DoomSeeker is a server browser that makes joining servers easy.
Connect to the Server:
With DoomSeeker:
- Launch DoomSeeker.
- Look for A-Net Doom Server in the list (or add it manually).
- Server Address:doom.a-net.online:10666
Manually (Zandronum):
- Open a terminal/command prompt in your Zandronum directory.
- Run: zandronum.exe -iwad DOOM2.WAD -connect doom.a-net.online:10666
Have Fun!
Frag your friends, try all maps, and enjoy classic DOOM action!
