At this year's E3 Nintendo Press Conference, the only surprise game announcement was Luigi’s Mansion 2. While the game had been hinted at in the past, I’m not sure anybody saw it coming so soon, let alone being playable on the show floor. The game is a sequel to the GameCube launch title. While no story details have been given the demo shows Dr. E. Gadd digitizing Luigi and sending him to a mansion inside of a computer. Or at least that is what it looked like. The playable portion of the demo then begins there.
