Oh don't be so immature – we know that Svetlograd sounds like the name of an especially butch Scandinavian pornstar, but it's not.
Actually Svetlograd is a pretty nifty little old-school arcadey type affair. Although Svetlograd comes pre-packed with a tired old story about protecting a city from advancing baddies with a magical cannon, what it really is is Centipede. A spellbindingly beautiful version of Centipede, granted, but Centipede nonetheless. That shouldn't stop you from giving Svetlograd a whirl, though – it's a beaut.
