Ys: The Ark of Napishtim (イースVI -ナピシュテムの匣- Īsu Shikkusu -Napishutemu no Hako-) is a Japanese action RPG developed and published by the Nihon Falcom Corporation, and the sixth installment in the Ys video game series. It was first released in 2003 for Microsoft Windows-based personal computers. Not counting the Eternal/Complete remakes of Ys I & II, it was the first new Ys game released by Falcom in eight years. The name Napishtim is a reference to the character Utnapishtim from the Epic of Gilgamesh.
