Saboteur II: Avenging Angel is a sequel to the 1985 video game Saboteur. Saboteur II was one of the first action-adventure games to feature a female protagonist.

The player takes control of a female ninja named Nina (a sister of Ninja, the deceased hero of the original Saboteur), who must break into a dictator's high-security compound to alter the course of a nuclear ballistic missile and then escape. The enemy’s command centre and office complex is being built on top of a mountain filled with underground tunnels and caverns. An armoury building is on the top left of the mountain, a missile silo is on the top right, while the central top area is still being developed; there is only one way out of the mountain, which is the long entrance tunnel on the bottom left.
