Deep Silver Homefront : The Revolution

Homefront: The Revolution is an open-world first person shooter where you must lead the Resistance movement in guerrilla warfare against a superior military force.
A living, breathing, open world responds to your actions - you and your Resistance Cell can inspire a rebellion on the streets and turn Occupation into Revolution, as oppressed civilians take up the fight.
But your enemy has the advantage - superior technology, firepower, heavy armour and air support. You must learn the art of guerrilla warfare – ambush, sabotage, infiltration, deception – and fight a running battle through the war-ravaged suburbs of Philadelphia.
And the single player campaign is just the start – in Co-Op you and your friends can form your own Resistance Cell and become renowned as Heroes of the Revolution
