If you like Halo 3 you will like this
Having thoroughly enjoyed the previous Halo games I was looking forward to ODST. Especially since it seems I am one of the few that had fun with the single player in all the previous games. The single player is a bit shorter than any of the previous games, but it is by no means too short for a full game. The story telling method is totally new to the series. It works with the main character being in an over world and finding points to initiate flash back stories. The last piece of the story is played out via audio logs that are found scattered about the over world (except for the last one). It is too bad you have to find these since they are really well done. When I watched the audio logs they immediately reminded me of the pre-release shorts put out for Dead Space. If this game needed hype I think the audio logs could have been released the same way to build up the story for ODST.
The game also includes a new co-op multiplayer mode called Firefight. I call it co-op because it has no matchmaking and is totally separate from the other multiplayer mode. The last mode is a second disc of the entire Halo 3 multiplayer experience, including all previously released maps. If you haven’t bought any of the maps then this is a good deal, if you have well you may feel a bit ripped off.
As my score says I would recommend this game to any FPS fan and especially Halo fans. As a standalone game I think it is worth it as well.
