It was ok but I did have a lot of problems with the game, mostly the characters as I didnt feel like they meshed all that well. The story was...barely there, as I recall and it didnt really bring anything new to the game. On top of that generally I found the game to be pretty ugly when compared to other games for the time (even more so now). Probably the most glaring thing, for me, was the price tag. A game I completed in 4 hours I think for $40? No it wasnt worth that price tag. Had it been 30 or less I wouldnt have had any problems with the price
The one thing I will praise it for is it cleaned up a lot of the driving mechanics, ODST was the first halo game where when I drove a warthog I didnt feel like I was going to fly into space when I ran over something as insignificant as a tin can
