By replacing it, I meant taking it out of the maps and putting another enemy in its place. Similar to how the devil stallion replaced the dragonman.
Regarding deathmatch maps, I don't really plan on making any of my own. I don't play deathmatch, so I don't know what makes a good deathmatch map. That's why I'm looking for somebody, who has experience working with them and leave it to them instead.
