Many of you may have noticed our review for Knights of the Phantom Castle last month, and for those who are interested in Hudson's title can now pick it up from off of the App Store for their iPod Touch, iPhone or iPad for more than half of the original price. Knights of the Phantom Castle has been marked down in price from $4.99 to $1.99 and it will remain on sale from now until October 19th, so if you are fan of classic 16-bit RPG's and especially one's that you can play while on-the-go, then this is a title you won't want to miss.
