It is going to be agood game in my opinean. It takes place before halo 1 and is more of a stratige game. You get to place the chatacers and vehicles in the game. You can have more than 1 sparten scince they haven't died yet in the story line. For the first time in multiplayer you can use the covenent charactors. So just imagen owning your friends with a group if hunters, a pack of pruts, and the prophet giving them orders. The system to select the troops is lso said to be very easy to navigate.
Hope this helps! =D
