This is a simple modified E1L1 map of the original Duke Nukem 3D which adds tons of enemies and changes the location of access cards or access card slots. Since it gets a lot harder, enemies are toned down a bit since they appear in large numbers.
Note: For now it's just E1L1, in the future there might be a full episode. :)
Mods Used:
1) Map Mirroring Mod
2) A single User map
3) Modified USER and GAME con files
