Sigma 7

SIGMA SEVEN is an all-action arcade game featuring imaginative state-of-the-art 3D graphics and exciting synthesised sound. There are seven increasingly more difficult stages to the game which starts-out easy but ends-up almost impossible. Each stage is split into three phases: first take a space-fighter and blast your way to the next station through swarm-mine defences, then free that station’s internal pathways of killer-robots and radioactive deposits, to finally reach the remote-controlled main panel which must be reset within a critical few seconds. May be played on keyboard or with a single joystick. Quick reactions essential.
