I think this game may be a new story in a new universe. It think it will take place in the future, with a dictatorship ruling over the world/part of the world. The Ghosts are a resistance group, fighting this government. Hence, "We are all we've got." The whole thing in the teaser about people who wear masks to prtect themselves and others may refer to the fact the Ghosts wear masks when fighting the government to free the people and to protect their identities so if they escape, they can live to fight another day.
