ODST is fun, it has good campagin and in my opinion I think its kind of better than the original halo 3, it's nice that it has all DLC maps, but it is kind of crappy for the people who bought the maps before it came out, but atleast we still had fun playing them before this came out, but it's cool that they give you an oprotunity to get recon armour but it will probobly get overused by players, firefight mode is pretty fun to, and the graphics didnt change to much and they give you a new mode which can be useful for battle called visor mode, I suggest you buy it if your a fan of other Halo games.
