Check out Brink's Intro As Well as New Security Gameplay
Two videos for your viewing pleasure; first, the intro to the game–accented narrator and all. Second, a video that showcases some new gameplay from the Security portion of the storyline. Both are new!
Interesting tidbit from the intro video: the Resistance is trying to escape. That…makes things interesting. Why wouldn’t Security allow people to leave? Wouldn’t that help out the situation–given that resources are scarce?
