In our interview with Lars Bakken of Bungie and Microsoft Game Studios' Ryan Crosby recently, the question was raised about the length of the game. This was met with an unexpected response considering the less rigid parameters that make up the ODST gameplay. Halo 3 offered a campaign in the region of 5-8 hours depending on difficulty and so to hear that Halo 3 ODST is going to be a shorter game is quite surprising.
