As we reach the final 20 in the countdown, it's pretty much stone cold classics all the way from here on in - and Planetoid is no exception! Originally released by Acornsoft in 1982 as Defender (until a hasty re-release for copyright reasons had it rebranded as Planetoid), this game developed by Neil Raine is a clone of the Williams arcade cabinet classic Defender. Watch me pilot my ship, blasting bad guys and defending the inhabitants of the planetoid, narrowly avoiding death (well, sometimes). A superb early 80s game with crisp graphics, sound and an array of amazing gameplay dynamics. Enjoy!
