DOOM II: Hell on Earth – How to gets mods running through Steam

Step 1. Get your source port into the game files

 
I would recommend GZDoom for heavy modding of the game. 
 
All you need to do is copy and paste all the source ports files into the base folder, and rename the executable to dosbox. Delete default dosbox. 
 
 

Step 2. Throw your mods into the Doom 2 folder

 
This place right here, i’m sure you recognize it. 
 
 
 
 

Step 3. Do a little editing

 
You want to edit either the doom 2 + mouse or doom 2 batch files, depending on which one you want to launch. 
Once you’re in the editor, the default code is something like this 
.\base\dosbox -conf .\base\doom2m.conf -fullscreen -exit 
 
Remove everything, leave the .\base\dosbox part 
 
Now, I wanted to run Eviternity.wad and Project Brutality 3.0 both at once through Steam. 
What you need to do is simply write -file and then just enter the names and file formats of your mods, and save. Then launch through Steam and it should work. 
 
So, since I wanted to run both Eviternity and Project Brutality 3.0, I entered this: 
 
.\base\dosbox -file Eviternity.wad Project_Brutality-master.zip 
 
Then just save and launch. 
 
Remember to choose to launch the dos version of the game when launching through Steam.
