Destroyer (Cidelsa, set 1)

Published in Spain in 1980, Destroyer is a single-player shooter that presents players with a familiar challenge reminiscent of Space Invaders. As the sole defender, you maneuver a stationary base along the bottom of the screen and target descending rows of alien formations. Destroying these enemies earns points, but failure to eliminate them results in their advance toward your defensive position. The game utilizes an 8-color palette on its display and runs using a CDP1802 central processing unit paired with a CDP1869 sound chip. Players must strategically manage their shots and anticipate enemy movements to survive the increasingly difficult waves of attackers. The gameplay loop is simple but demands focus and precision, providing a classic arcade experience for those familiar with early shoot 'em up titles.
