Doraemon - Giga Zombie no Gyakushuu (Japan)

Doraemon - Giga Zombie no Gyakushuu is an action-adventure game with light RPG elements, released on the NES console. Players control the robot cat Doraemon on his quest to stop Giga Zombie, a villain who has turned the inhabitants into terrifying zombies. The game combines exploration of a vast world with side-scrolling action combat.

Each stage in Doraemon - Giga Zombie no Gyakushuu typically begins in a town or safe area where players can talk to NPCs to gather information or receive quests. Afterwards, Doraemon must venture into dangerous areas such as forests, caves, or zombie-infested buildings. The gameplay primarily involves horizontal scrolling, jumping over obstacles, and fighting enemies.

A unique aspect of the gameplay is Doraemon's gadget system. He can use various gadgets as weapons, each with its own utility and energy consumption. For example, the Air Gun is a basic weapon, while the Small Light can shrink enemies. Managing gadget energy is crucial, as Doraemon cannot use them when energy runs out. Players need to collect energy-restoring items or find charging spots.

RPG elements are evident as Doraemon can level up after defeating enough enemies, which increases his health points (HP) and attack power. Furthermore, Nobita also plays a significant role. Although not directly controlled, Nobita can be summoned in certain situations to assist Doraemon, such as using his "courage" to overcome mental obstacles or aiding in combat.

The game features various enemy types, from common zombies to larger monsters and boss characters at the end of each major area. Boss battles require players to master gadget usage and strategic movement. Additionally, Doraemon - Giga Zombie no Gyakushuu includes secret areas, minor puzzles, and hidden items for players to discover, encouraging thorough exploration.

Game saving is typically done via a password system, a common feature of NES games of that era, allowing players to resume their adventure from a saved point.
