ODST isn't that different from halo 3. besides night vision theres no difference plus you're a lot weaker.

There isn't much difference b/w Odst and halo 3. The gameplay is the same and it kinda sucks that you're not that strong. The only new feature I see is firefight. I kinda thought that you could play online as the Odst members but I didn't expect them to give you a multiplayer disc with all maps from halo 3. Now I kinda wonder about how many microsoft points I used up to get the maps. They did improve some of the weapons like the smg and the magnum, but I noticed that there weren't any BRs. Even with those things, Odst does have a good storyline and it's kinda cool how they didn't show the rookie's face. You get to play as Sgt. Johnson which is also beast. In my opinion, Odst is alright but they should've changed or actually added some more features to it like running or cooking granades. Ling review short, it's kinda Beast.
