Prison is a post-apocalyptic action-adventure developed and released by Krisalis Software in 1989 for the Atari ST and Amiga.
In this game created by Peter Harrap (author of Monty Mole) and Michael Hart, you are a prisoner on a desert planet, devastated by a nuclear war. Your goal is to find some ship pieces useful for repairing a vessel that crashed on the planet and finally escaping your prison.
For the most part, the game is a point-and-click adventure, with fixed screens and a bi-dimensional side view. But there are also some arcade sequences, where you will have to fight some aliens that will try to kill you. This mix of genres is not totally convincing. Still, the atmosphere is really great, with a sense of darkness and loneliness communicated with the graphics (better on the Amiga than the Atari ST version) and the excellent music.
If you are a fan of dark science fiction and want to try something different, this original title by Krisalis is for you.
