NAM was released in 1998 for DOS PCs. It runs on the Build engine and reuses a lot of code from Duke Nukem 3D. So much code is reused that you can actually run NAM in eduke32. A source port for Duke Nukem 3D.

This allows for

-playing the game in a widescreen resolution. Can run at resolutions like 3072x2304
-easier to play custom maps
-Much faster framerate
- adds a full-featured console, including Quake-style key bindings, command aliases, advanced tab completion, comprehensive command history, colored text and more
-adds tons of optional new features that make the player's life easier including modern status display/HUD, support for loading mods from the startup window, and modern, WSAD-based controls with thoroughly reworked mouse aiming

Thankfully this is easy to install. I'll go over the steps bellow.

Go to

http://www.eduke32.com/

and download the software by clicking the Windows icon

After downloading. Use .7zip to open the file. You should be greeted with this


Now navigate to your NAM folder. This is commonly located in

C:\program files (x86)\steam\steamapps\common\NAM\

Extract the contents of the .7zip into your dosbox_windows folder

Now. Go to your NAM folder



Copy all of the files in this folder into the dosbox_windows folder

The game will now run if you run eduke32.exe, click "NAM" under the GAME section and press the START button



If you want the Steam overlay to work. Go back into the dosbox_windows folder and right click the file named dosbox.exe. And rename it to dosboxbackup.exe or delete it.

Then rename eduke32.exe to dosbox.exe



You will now be able to run the game from inside the Steam client and you will have the overlay.

If the game still doesn't work. Go back into your dosbox_windows folder and rename GAME.CON to NAM.CON

If you wish to revert the game back to the way it was. Go to your steam library and locate NAM


Right click it and go to properties

Then go to Local Files and press Verify integrity of game cache.



This will restore the game back to the way it was before.
