Space Cavern (Atari 2600)

You command an intergalactic starcruiser that has landed on a mysterious planet riddled with smoky caverns inhabited by savage Electrosauri whose horns generate deadly electromolecular charges. The Electrosauri stalk you, their horns crackling and sizzling. If even one blast of energy strikes you, your skeleton will glow as you disintegrate. Warning: Beware the shaggy marsupods!
