Force Seven was programmed by Ken Grant and published by DataSoft in 1987. The game resembles the legendary "Gauntlet", nonetheless it can't be considered as a mere clone since it brings a lot of fresh improvements.
Force Seven is set on the planet 'KARIS'; your orders are to infiltrate an energy production plant, free any survivor and kill all Hostile Alien Forms.
The main idea behind it was source of inspiration to later games, like Alien Breed by Team 17 for Amiga.
