The dark passenger will arrive soon. Dexter for the iPhone is here at E3 this week. However, my hands-on session was a bit different than previous engagements with the iPhone game based on the smash Showtime serial killer series. This time, Marc Ecko Entertainment just turned me loose with the latest version of the game to play through the first scenario without any guide or interruption. It was just me, Dexter, some dead children, and a bonesaw.
