VS4 (F) (1987) - Amstrad CPC - Simulation, Sci-Fi

You have to leave the VS4 base and return to your home base on Venus, but first you must explore VS4 and find the evacuation sphere that will fly you home. This game consists of two parts. The first part sees you exploring a large maze of rooms avoiding enemies. Any contact with them will reduce your energy. The rooms are drawn in an isometric perspective, and while the graphics are not too bad, some terrible choices of colours are used in a lot of the rooms. Once you've located the sphere, you then play a simple 3D shoot-'em-up with enemy spacecraft heading towards you.
