One of the best action and strategy games i have ever played. I have spent hours playing this game and just love it. All the good aspects of both the previous versions (Halo 1 and Halo 2) are brilliantly covered in this one. The missions started in previous one comes to an end here (though I don’t think the end is perfect). Halo 3 has lot there to boast about. First thing, its fresh and you can see the innovation and creativity there (some people who have played Halo 1 or 2 may say that there is not much new but i don't agree). Better weapons, enhanced skill sets, wiser strategy all are a part of this new version. The levels of the games are designed in the best possible way.
But when played in the single player campaign mode it is too short and i hate this. There is some improvement in the graphics but the most prominent feature where this version excels is the Multiplayer option. You are going to have one of the best Multiplayer experiences.
You will enjoy every single buck you spend on this.
