Brink is one of the last bastions of hope for the hardcore PC gamer; in a world that is becoming increasingly dominated by consoles and lousy PC ports, the days of the old fast-paced PC FPS games almost appear to be coming to a close sometimes.
The new E3 trailer starts off with the character customisation, then some weapon customisation before launching into gameplay proper. There's some example footage of interacting with various parts of the environment in addition to the actual running around and shooting. The trailer gives you a feel for Splash Damage's typical objective-based approach to multiplayer game design as well, showing team members performing certain tasks and the audio cues you get when control points change hands.
