America's Amry And .run Extension

Does anyone know what to do with a .run extension on a file? I downloaded America's Army for linux and it had a .run extension which I never saw before. I spent about an hour on google looking for what king of file type this is, but found no insight. Anyone extracted or ran this before?

EDIT: I found this on a website:

RUN: Compiled output p-code file (Softworks basic compiler) (SoftworksLtd)

I'm not at my computer with Opensuse on it right now but does softworksltd exsit on the installation dvd?

Try to run the file, It worked for me.

#/_.run

Thanks I'll try that.

I had no success at being able to run the file.

sh filename.run should do it.

Thanks that did work, but I still have a problem. When I go to run the application I get a splash screen of America's Army and then it closes. I saw that it said it was an SDL application, so I went into yast and installed some packages related to SDL but that didn't help. I am running as root, but it made no difference. Any suggestions?

This is the reason I can't start the game. I get this error:

open /dev/[sound/]dsp: Device or resource busy
Couldn't set the video mode: Couldn't find matching GLX visual


What can I do about this?

I download it as I write.
Will post some comments when I'll try to run it...
