If you are planning to use this for something new, I would like to be credited please. (I know it probably won't happen, but maybe
you won't do what I did: take prefabs and not credit the prefablab authors and TWHL). Nonetheless, here are the instructions to open up
the map successfully in Valve Hammer Editor

1. Place de_nuke2.wad inside your zhlt directory
2. Include de_nuke2.wad inside Valve Hammer Editor
3. Open de_nuke2.rmf inside Valve Hammer Editor
4. The compile parameters are for zhlt253-17
5. Rename the compile.txt into compile.bat
6. Place compile.bat inside your zhlt directory
7. Save as de_nuke2.map into your zhlt directory
8. Copy lights.rad inside zhlt directory
9. Open compile.bat
10. Enjoy!

default wads used: halflife.wad and decals.wad from valve folder
