• DS version based on console versions
• Wii version - Wiimote controls camera, aims and shoots your weapon, and use various objects found in the game. Nunchuck moves your character
• DS version will feature gameplay elements much like the PC game Missing: Since January. You can read details on that game here

I remember playing an Alone in the Dark game for the GBC :)  Good times—the gameplay is reminiscent of Hotel Dusk.
