Energy (UK) (1987) - Amstrad CPC - Puzzle, Action

In a dark future, you are responsible for 3 regions (each divided into ten sections) which you must keep clear of aliens - but be careful as a section will seal once cleared - even with you in it! Your mission is simple: make your way to the Planet Zub 10, steal the green eyeball of Zub and return to Zub 1. Use the Zub Teleport Network to travel undetected. Each planet has 3 teleport units which are in orbit, a mile or so above the planet surface. To reach them you must cross a series of floating platforms which can be moved left or right. Each of the 3 units will transport you to a different planet within the Zub system. Each planet is protected by its own fleet of security robots. Watch out for the ZIRK BOMB, accidentally activating this could be disastrous.
