The A - Z of Spectrum Games

Sigma 7

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.
