The game will continue the story of the first game with "a much darker and more sinister story that leads your character down a path of betrayal, revenge and redemption against the city that has left him for dead."
The entire single player campaign will be playable in online and local play co-operative mode. New vehicles include boats, motorcycles, helicopters and planes. The player will be able to use limpet mines on cars, walls, and other surfaces as well. There will also be changes to Stilwater, including expansion of the west side of the city. The game will include additional weather effects. Pedestrians will be much more responsive to both environmental stimuli (such as opening umbrellas at the sign of rain) to possibly crowding around someone that has just been shot, allowing the player to use the distraction to get away. Alternatively, the player can attempt to use other characters in the game as human shields. The game will allow for personalized character creation, but will expand to include the creation of female characters. The player will also be able to expand and customize his "crib" through the game.
THQ has stated that with Grand Theft Auto IV due out prior to the release of Saints Row 2, they plan to allow Volition enough time to completely finish the game in order to obtain the best quality game possible. Additionally, the graphics engine has been improved to reduce the amount of "pop-up graphics" due to draw distances that were criticized in the first game.

Will be interesting to see how it compares to GTA IV. I really liked the last one and if they carry on it could be good competition for GTA.
and the single player campaign can be played co-op online??? Sounds incredible
