Back in April we previewed Chillingo's upcoming castle defense game Knights Onrush, developed by MoreGames, the folks behind iDracula and Origins: Legend of Wizards.
Knights Onrush is a castle defense game in the vein of the popular StickWars [App Store] and Defend Your Castle [App Store], but with much improved graphics and an apparently wider variety of defense methods.
Chillingo has just posted a new gameplay video of the upcoming title. (See the earlier video here.)
Knights Onrush has already been submitted to the App Store and is expected to be available any day now. It's currently being discussed in a lengthy thread in our forums.
