The House of the Dead III

The easiest place to get this is in chapter 4A (or if starting from the beginning of the game, take "Entrance" in chapter 1, then play the "Fool" boss level and then the "Sun" boss level leaving "Death" for last). After you encounter the vultures on a narrow bridge passway (enemies will jump down after the vultures) there is a barrel to the left as you move across the bridge. A zombie with a saw will saw the glass you are approaching, ignore him and shoot the barrel and shoot the hell out of the wind up toy (Mecha Zombie) that comes out of it. Killing it will net you 3000 points and this trophy.
