Putting aside all those fascinating dungeon crawlers, it's time to mention Salvador Cantero's arcade release of 'Red Planet', which is now available to play on the ZX Spectrum. Powered by The Mojon Twins and title screen by Mike Smith, Red Planet is a jet pack jumping and shooter platformer, that was made available just yesterday as a tape based file. With lovely 8-bit detail and enemy designs, Red Planet is completely free. But I must warn you, it's not an easy game to master!
