Wow, one of the best Halo games I ever played in a long time. Definitely worth it to every Xbox 360 owner.
Now lets talk about the Campaign. In the Campaign,you start out as the Rookie, a shock trooper and the newest member of his squad. As you drop your drop goes wrong. You crash in the city and you basically pass out for about six hours (I think). When you wake up, it's night and you are alone in this new film noirish cityscape. What you are doing is fighting around the city and looking for clues that link you to flashbacks. These flashbacks are short, high-action scenes that take place after the drop. You essentially play as other members of the ODST squad and experience the part of the day that you missed while you were passed out (Which it happens a lot). Eventually, the timelines converge and the Rookie hopefully meets up with his surviving squad members and they make it safely out of the city. This will keep going on to the end, but its not just that, its about the Storyline in the game, and the action. The Storyline in this game is like in all Halo games, you kill Covenant like, but in this game, it actually experience more of the Characters this time around then the Past Halo games. As I said earlier, you switch to other ODST Soldiers, and experience more of there Personality in the game. My favorite Character in the game is either Buck or Mickie. Buck is just an Awesome character to be buy and I like his him for some reason. Mickie is just Funny, especially playing Firefight with him, he's funny. The Campaign lenght is around 6-8 hours, yet Short, but it has really great Replay Value in the game since you could do Campaign Scoring, turn on Skulls, Achievements, CO-OP (Online or Offline), and other stuff to keep the Campaign fun and entertaining.
Now theres the number on reason why people buy this game, the Multiplayer. ODST pretty much have no Multiplayer, besides Firefight and another Halo 3 dist (Later on, I'll talk about that). Firefight is like Horde from Gears of War 2, except that it has no Matchmaking in the game and it has Skulls on (Randomly when the game starts, besides Silver Skulls) so that it'll be Challenging. You could Invite your friends to Firefight and kick some butt. Yes, it has no Matchmaking in the game (Which I said earlier), but just Invite your Friends or Family members and kick some butt in Firefight and have fun. It never gets old of playing Firefight since you could pick your Own Character from the ODST game (Not customize like Halo 3, but you could change your Colors) and just experience some cool Dialogue when you play as them, expecially if your playing with someone like Mickie in the game, or, Sargent Johnsion in the game (Which you only get him if you Pre-order it before the game came out). Either way, its a good way to experience some cool stuff with the guys when you play as them. My favorite Character (like earlier ago) has to be Mickie, because he has some funny Dialogue in the game and its really fun to listen to, but my 2nd favorite Character to play as in Firefight is Dare (With the Recon helmet), mainly because Recon looks like a Cool helmet to look at and I also like her, not much as Mickie or Buck, but she's pretty cool, but definitely my least favorite character in the Campaign, but still a cool person to play as in Firefight. You could also take pictures on both Firefight and Campaign and put it to your File Share, if you do, then if you play the Halo 3 disk in ODST (The 2nd disk in the ODST Copy), everyone could see your ODST Pictures in your Fileshare if you do add if to your File Share (Which has all your Halo 3 Videos or Pictures in your File Share so that people could see it). That's pretty much it for Firefight.
That's it for ODST, now lets start the 2nd disk in ODST, the Halo 3 Disk.
Now theres another Halo 3 disk in the ODST game, its separate (The second disk in the ODST copy), and it has all the New maps in the game that you didn't brought is in the Disk, and of course, another 3 new maps in the game so yeah. It has all the gametypes in the game, but if you bought ODST, you got some new Gametypes to play since these Gametypes are only in the Mythic Disk only (The 2nd disk you have in ODST), like Team Mythic, Team Throwback, Double EXP Weekends (Some), Big Team Mythic, and I think that's it, but theres going to me more pretty soon so whatever. The only difference in the game that it has No Campaign in the game and it has a New Main Menu in the game, and of course, it has some new Music in the game (Besides the beginning when you start it up), and I think its pretty cool IMO. Besides that, its all the same and it has everything you have in the original Halo 3 disk, like all your Forged maps and Custom game stuff in the game so don't worry if your thinking everything is gone, its not. Oh, and it has all your Armor and stuff in the game so don't worry about that either. That's pretty much it for the Halo 3 disk in this one so yeah.
That's pretty much it for the Review and Im giving this game a 9.5 for being an incredible game to the Halo Franchise and I can't wait for the Reach beta in this game (Which it will start early 2010) and its definitely worth it to every Xbox 360 owner, and to every single Halo fanboy their is.
Have a nice day to all.
