Halo 3: ODST...best games till now of 2009, I really love Fire Fight Mode!!! Super fan to play with your companions, the campaign is boring alone, it gets a bit lonely, just doing the same thing, and you don't really get the Halo 3 atmopshere but it's still awesome. I'm so happy ODST changed it's sub machine gun and it became better aswell as the Pistol, now with aim support. I could not stop playing fire fight mode in Lost Platoon map, super awesomeness.
Despite all the bad remarks, bad campaign, it's still awesome and I really think you should buy it...now!
