Although you can play the game as a standard first person shooter working together with your teammates is the only way to succeed, with each squad pursuing different tactics and objects - from directing air strikes, to taking part in parachute drops and overrunning enemy gun emplacements.
As you gain more experience in the game your character's abilities and weapons will improve and evolve, with the best players earning the right to command more and more people and take a greater strategic role in the wider conflict. This is all out virtual war on a scale that has never been possible before on a home console.
