Halo 3: ODST

To summerize the new game Helo 3: ODST, I took a summary from http://www.gamespot.com/xbox360/action/halo3untitledodstgame/review.html?om_act=convert&om_clk=gssummary&tag=summary;read-review:
" In Halo 3: ODST, you wake up all alone in a hostile city. Pockets of enemies are hiding in the nearly pitch-black environment and your allies are nowhere to be found. In the opening moments of Halo 3: ODST, you are vulnerable and aimless--two elements that have never been explored in a Halo game before. These quiet, moody scenes flow into the spirited, high-energy battles the franchise is known for, but this feeling of desolation never fully dissolves. ODST is an awesome entry in the franchise because it not only showcases the elements that have made previous games in the series so explosively fun, but it also introduces a handful of new ideas that add a unique spin on the classic formula. The most exhilarating of the new features is the Firefight mode, a cooperative battle against a never-ending swarm of covenant soldiers that is as intense and rewarding as anything that has appeared in the series. Whether you love the solitude of the single-player campaign, the camaraderie of cooperative encounters, or the blood lust of multiplayer competition, Halo 3: ODST is a fantastic package. "

My opinion:

I myself enjoyed very much the Halo 3, and believe that ODST is a good incrementation to it. ODST includes and shows new materials of the game, such as the Firefight mode, and the continuation of the story. I have beat the whole game of halo over and over again (if I was to count, I would say about 8 times), since I loved it. Reviewers of the game say that comparing with the anterior one, it has improved multiplayer campain, and maps. I think that since the first Halo, it has always been a success, and I think ODST will be the same way.
