ODST imho looks amazing i like the refinements that Bunige has made to the game engine and also the fact that they are speeding up the gameplay slightly due to the fact of not having shields it is leaning more towards COD kind of gameplay i played halo 3 up to a couple of months ago when i got COD i went back to halo and it seemed very slow looking at this it looks really good i like the way the textures have been improved and the story seems to be a good one though i'm keeping away from the spoilers of the campaign.
