It had a different feel and vibe while I play this game everytime I play it it has a lonely feeling but an amazing lonely feeling because u can relate with rookie because he is alone, lost, and afraid it also has a well put together campaign and the music is amazing i love the sound effects ecspecialy the raining sound effects the game was overall made well for a 2009 classic shooter this is what real halo feels like and I suggest this game to anyone.
