Llamasoft's neon arcade shooters

These six games from Llamasoft Ltd. give you short bursts of old-school arcade shooting wrapped in bright patterns and driving music. POLYBIUS sends you speeding down a tunnel while you blast what comes at you, Tempest 4000 keeps you circling a rim to clear waves of enemies, and Akka Arrh asks you to guard rings while you link shots for points. The rest follow the same idea: simple controls, quick restarts and score chasing that rewards focus and reflexes.
