Undercroft is a free iPhone and iPod touch "old-school" style RPG originally developed and released in 2005 by Rake in Grass, an independant game developer. A PC version also existed, but was removed from markets as the game underwent various updates. In 2010, Jagex purchased Undercroft (gaining all rights to the game) and repackaged it as a free download.
