I got this from a YouTube video too. One of the first Halo games I ever played on the Xbox 360 is Halo 3:ODST. In my opinion one of the most underrated series in my opinion because of the music and atmosphere of being a lone soldier finding the troops that you think are dead.l and also finding collectibles of what happened in the city. Although the game is short it's a well-done game. I give it an 8 out of 10.
