Three years ago today, Halo 3 ODST came out. Some loved it, a lot hated it purley because of it’s length, but I was one of the people who loved it, and I will always consider it my favorite Halo campaign (at least until Halo 4, 5, or 6 take it down, if they do). Great story, great characters, outstanding voice acting, dialogue, and atmosphere, and absolutely beautiful music.
ODST is a great game, probably becuase it opted to be so different than the others. As much as I love Master Chief and Noble team, being exposed, clue searching and simply seeing the devastation left behind during the events of H2 make it something to remember.
if you are looking for a sequel it most most likely end up being more like reach in the sense that you would be a team of spartans. mostly because from what iv heard and read up on you can choose to become a spartan 4 so im sure a number of odst’s would have made the switch.
