Doom && Alien Doom

[caleb]

Hello,
          I am a doom addict and I just found out that doom is available 
from the ports tree :) I could install doom legacy but needed to 
download the doom.wad file and copy it to the doomlegacy directory. I 
could then run doom with no problems but because it is shareware I could 
not use all the weapons. I really want to be able to get Alien Doom up 
and running but I am not sure which files I need. Is there a full Linux 
version of Alien doom that I could get off the net?

Cheers,

Caleb
