Not sure how to install nonarch.rpm files on /Downloads

Got this package : http://freecode.com/projects/transmageddon . not sure how to change to downloads directory and install.

 

Then Using, not fusion, but the standard

> sudo apt-get install rpm , still not sure how to install this package .. Do I need to Unarchive or de|restrict ?

What dependencies would this need to be installed ? & are those already installed on elementaryOS ?

 

$I note the command for rpm files is #rpm -ihv Efilename.i686.rpm or Efilename.i386.rpm
