Play Global Defense Online
Dodge neon alien swarms in your slick little jet, panic at screen-filling bosses, then grin when your spread shot turns the tide—pure '80s arcade rush with stupidly smooth controls. That synth boss theme will haunt you.
Global Defense came out for the Sega Master System in 1987, developed and published by Sega. It was one of the many shoot 'em ups available on the platform, offering a straightforward take on the genre without much pretense.
You pilot a small, nimble ship tasked with clearing each screen of enemies before advancing. The main objective is to survive increasingly dense waves of alien craft and defeat large, screen-dominating bosses. Key mechanics include collecting power-ups to enhance your weapon, such as a wider spread shot, and navigating tight spaces while dodging intricate bullet patterns. The pacing is relentless, and the difficulty ramps up quickly, demanding sharp reflexes and memorization. It feels like a tense, focused battle against overwhelming numbers, where every narrow escape brings a shot of relief.
