i found a very cool app for you android users called "zedge" just type it into the marketplace and it is a free download. it has thousands of ringtones, wallpapers, and notification (text) sounds. you do have to make an account i do believe just give an email ( i did) they have xbox games sounds, super nintendo, gameboy sounds mario pacman and much MUCH more. they have ALOT of halo sounds you can use as ringtones and text sounds, a few off my head are "wort wort wort" "superintendant sound" "sniper shot" "killing spree" "untouchable" "triple kill" and ALOT more. ive got the superintendant one just cuz it sounds cool. and these are all high quality sounds. check it out. i dont own the app or know who does, just thought it was cool for people who have android and love video games. :) **** to get to the halo sounds just click search, and type "halo" and click notifications or ringtones. itl show alot of cool sounds im downloading some now :) [Edited on 05.02.2011 1:55 AM PDT]
