how can i open a file thats download? ?
 

I download a game called AMERICA'S ARMY of the web, this is suppost to be a linux version. Now i have a file on my desktop, What do I do with it? How can I open it?

You'll have to give a bit more information. What version of Linux are you using? What's the full name (especially the extension) of the file you've downloaded?

Also, do you have to kill innocent civilians for the crime of being in the wrong place at the wrong time?

It's probaly a script. I don't know what desktop environment you are using so I will tell you how to run it from the command line.

open a terminal and change to your download directory

then run it
