Gradius is a Konami shoot em up for the NES, built around side-scrolling space combat against the Bacterion Empire. The mission centers on a hyper-space fighter pushing toward the Xaerous Superfortress and its Bacterion Bio-Computer.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• Side-scrolling shooter gameplay emphasizes enemy waves, projectile dodging, and survival through hostile space zones.
• The fighters arsenal includes air-to-surface weapons and double beam laser cannons for expanded firepower.
• Force fields provide defensive support during heavier enemy attacks.
