The story for the single-player experience will deal with a terrorist-like American populist group calling themselves the 'True Patriots' (Tea Party?) which is the inspiration for the game's subtitle.
Dialogue in the trailer has the True Patriots accusing their hostages of corporate greed, with their leader claiming that they are acting on behalf of the victims of economic inequality.
From the description it sounds more like the OWS movement.
I have given up on FPS games. If I want to shoot stuff or blow shit up, I just go and do it.
