Game Description: Zanac is a top-down, vertically scrolling shoot-'em-up where players control a spaceship battling against waves of enemies in a futuristic setting. The game features dynamic difficulty that adjusts based on the player’s performance, making each playthrough unique. Players can collect power-ups to enhance their weapons and ship's abilities, with the ultimate goal of defeating enemy forces and progressing through increasingly challenging levels.
Note: The transition from 5-screw to 3-screw cartridges in Nintendo Entertainment System (NES) games was primarily a cost-saving
measure implemented by Nintendo during the late 1980s. This change occasionally coincided with updates to other aspects of the game's
packaging, including the Universal Product Code (UPC) and/or a color change to the Nintendo Seal of Quality (SOQ). Not all NES games
underwent a UPC change during this transition and many retained the same UPC across both cartridge designs.
