I <3 Halo: CE - started it all
I played ODST again today.
I love it. I forgot how much I missed it. I got so hooked with Halo:Reaches campaign that i forgot all about how awesome ODST's was.
The music.
The look of the destroyed city.
The story.
It all adds up to be an awesome game, and I was actually getting a sad feeling when a song came up while I was walking around in Destroyed New Mombasa, knowing that 9/22/10 is long gone, and not much people play ODST anymore.
I love Every Halo campaign, by ODST's is by far the best and I will continue to beat the campaign again throughout this week.\
Thanks Bungie for an awesome game!
