I built a map for deathmatch and dueling last week.
I don't really do much 'Dooming' these days but it's always fun to churn out a deathmatch map.
It integrates some modern features such as 3d floors and jump pads into what I would think of as a traditional Doom deathmatch map to keep things fresh and interesting.
Jumping and crouching is not recommended (you can easily bag the plasma with one leap) - more info can be found in the readme.
Hope you have fun playing it.
