This Van Helsing theme's not just for fans of vampire lore. The game itself combined a wide variety of concepts in an ambitious attempt to merge folklore with science -- adding a touch of RPG goodness to round it all out. The theme conveys those concepts very well.
Apart from the titular hero, you've got a rather bizarre, alien-looking creature and a sinister robot, while giant clockwork dominates the background. The parchment-themed icons add a nice touch too. It's another one that's especially suitable for a Halloween theme, but fans of what goes bump in the night and Diablo-style RPGs can enjoy it year-round.
