Planetoid

About

You're piloting a spaceship above a planet's surface blasting waves of attacking aliens. Planetoid tasks you with defending scattered human figures from enemy swarms using rapid-fire lasers and a limited supply of powerful bombs. The BBC Microcomputer System version captures the tense pacing of its 1980 arcade inspiration with simplified but responsive controls. Each wave forces careful positioning as aliens move in unpredictable patterns and your resources dwindle fast. Despite being a direct Defender clone, Planetoid earned a cult following among 8-bit enthusiasts. Its 1982 release date makes it one of the earliest attempts to adapt the formula to home computing, with chunky pixel art and sharp sound effects that still hold up. Community discussions often highlight its punishing difficulty spikes and how the smart bomb mechanic feels more rewarding than in later ports. The single-player focus and retro aesthetic keep it relevant for fans of vintage arcade conversions.
