Very cool game for the PS2
Get a light gun, and play it in a dark room
you move your character around with the directional pad on the gun, look for clues and bullets, just like the other RE games
But when a zombie shows up, you pull the trigger on the gun to go to 1st person mode... then you blast them
And it takes place on a cruise ship, you kinda feel like playing the movie Ghost Ship except its with zombies
