High Quality Content by WIKIPEDIA articles! Obsidian is an action-adventure computer game for the Amstrad CPC personal computer published by Artic Computing in 1986. The game is set on the titular space station located within the centre of an asteroid, which is out of control and drifting towards a black hole. The player must guide an astronaut with a jet pack around the station and re-activate its engine shields to prevent the Obsidian`s destruction. This involves collecting items and using them to solve puzzles, while avoiding the Obsidian`s reactivated security systems.
