Need help with editing a monster

[A Dense Goblin]

I'm making a wad for doom II, and i decided it would be a cool idea to use the Nazis found in the secret levels, but I want to make a few modifications to them, first. I know the basics of modifying monsters (using slade), but how would i load it so that the enemies show up within the level data on slade?

Have you set a DoomEd number for the modified monsters?

First you have to choose what ports you want to aim for if you want to aim for vanilla or boom you will have to get a program for making dehacked patches and watch/read some tutorials I honestly don’t really know where to go for that though because I mainly use zdoom based ports but if you want to aim for a zdoom derivative port then I suggest you check out the nazis on zdoom wiki https://zdoom.org/wiki/Classes:WolfensteinSS oh and if you do go for a zdoom port make sure to read up on inheritance https://zdoom.org/wiki/Using_inheritance
