Metroid

Screenshots

Samus Aran stands on a blue-tiled floor in the center-left of the screen, rendered as a small orange and yellow sprite. The surrounding architecture features blue brick walls and platforms arranged vertically on the right side. A horizontal blue platform extends across the upper-right area with a yellow enemy or object above it. The top-left corner displays a health counter showing 30, while the top-right shows a yellow item or power-up icon. The background is entirely black, and the entire scene uses NES-era pixelated graphics with a limited color palette of blue, orange, yellow, and black.
