New mashup, as I said yesterday. This mashup is a multiplayer mashup using Halo 4 music, not anything else (other than the Foward Unto Dawn part). Enjoy it, it might be a little sloppy but bear with it!
"A new mashup comin' right at you. This mashup is a multiplayer mashup that is much like a trailer. It may be sloppy at some points, but bear with it and enjoy the awesome!"
