About Global Defense (usa, Europe)
Global Defense was released for the Sega Master System, a Sega-developed title from the late 1980s. It was one of many shooters on the platform that tried to capture the arcade experience at home, using the then-current theme of the Strategic Defense Initiative as its backdrop.
You control a crosshair, moving it across the screen to shoot down incoming missiles, aircraft, and satellites before they destroy your cities. The main objective is to protect your bases at the bottom of the screen across multiple stages. Key mechanics include managing a limited energy supply that depletes with each shot and recharges slowly, and defending multiple cities simultaneously as the attack patterns grow more complex. The pacing is relentless, and the difficulty escalates quickly, demanding precise aim and constant attention. It feels like a tense, high-stakes battle against an overwhelming barrage.
