Even if you are a hardcore 24 addict like myself; this game is not worth it. Gamespot has it spot on--on this one.

Cambridge Studios brings you into the world of every key player – be it Tony or Kim – and allows you to experience their role in the terror-filled day through a highly variegated gameplay design. If Jack calls CTU for a thermal satellite reading of hostiles in his area, you'll be asked to fulfill his request. You'll have to move the satellite into position, scan the interiors of the building, and highlight all of the potential targets that you find. Once this action is completed, control switches over to Jack, who is positioned to take them all out with a sniper rifle.
Within the course of 24 hours, you'll find yourself weaving through traffic, retrieving computer data, interrogating a junkie, unloading countless rounds from a helicopter-based turret, and even posing as a tourist at a government facility. The shifting gameplay keeps the action fresh, but the quality of these individual components is far from respectable. The core run-and-gun gameplay offers a nice assortment of rapid-fire weapons, but also a clunky targeting system and enemy AI that seems to be based on finding the easiest way to step in front of your bullet.
