Tenchu: Return From Darkness is set in 16th century Japan, where rebellions and civil disorder are rampant. A powerful sorcerer seeks to gain ultimate power from an evil god, aiming to become the unquestioned ruler.
The player takes on the roles of Ayame and Rikimaru, completing missions for their master Lord Gohda in an attempt to bring peace to Japan. As they progress, they eventually defeat the evil Lord Tenrai. The third playable character, Tesshu, is a doctor by day and freelance assassin for justice by night. After completing Ayame and Rikimaru's quest, the player can guide Tesshu through a handful of missions, seeing Japan from his perspective.
The game focuses on stealth, with the player rewarded for playing undetected and executing "stealth kills" to gain bonus weapons and items. Open combat is cumbersome and unrewarding.
Tenchu: Return From Darkness features 6 co-op missions for two players, allowing them to choose from the three main characters. The game also includes a versus mode with 20 characters, including enemies and bosses, available in split-screen or network play.
The game is an enhanced port of Tenchu: Wrath of Heaven , which adds new features such as:
Two new single-player missions for each character
