ODST isnt the best Halo game but dedicated fans wont complain.
Good voice acting that is hurt by lack of dialouge between characters, Sound effects are solid but recycled from Halo 3, and the soundtrack isnt as good as Halo 3 either.
Visuals: 9/10
Character models look good and the environments look good as well but once again it's not as good overall as the previous game.
Playability: 8.5/10
Same Halo combat that we know and love from the previous game, Nothing has changed for ODST and that is highly disapointing because it makes the game seem like a recycled waste of time.
Delivery: 8.5/10
Campaign isnt as long as the previous game but it offers a solid side story that is worth listening too. The addition of Firefight mode is a great addition and really saves this game from being a huge waste of time and money. The reason I hate this game so much is because it's so heavily recycled from Halo 3, I dont wanna pay 60 dollars for a game that is so similar to a game I already own.
Achievements: 8.5/10
Achievements are easier to get in ODST because of lack of multiplayer achievements, Wont take as much time either but the Firefight achievements can be a bit bothersome if you dont have any solid players around you.
Overall: 8.5/10
Too much is recycled from Halo 3 to make ODST as good as it could be but the addition of Firefight mode saves it from the depths of disapointment.
