# Zombie Nation (video game)

Zombie Nation is a 1990 Shoot 'em up game developed by KAZe and published by Meldac. It was first released in Japan on December 14, 1990 before being released later in the United States in January 1991.
The game revolves around the floating samurai head Namakubi goes to the United States to destroy Darc Seed—an alien who crashed to Earth via a meteorite in 1999, turned all the American people into zombies, and took control of various deadly weapons. Namakubi must recover the samurai sword Shura and destroy Darc Seed and its minions. This game features a juxtaposition of zombies, aliens and samurai.
Takane Ōkubo, its designer, had previously worked on Bōken Danshaku Don: The Lost Sunheart, a similar title for the NEC PC Engine.

## Gameplay

Depending on the version of the game, the player controls the giant levitating disembodied samurai head Namakubi (生首, namakubi, lit. "severed head") or a giant Tengu mask. The player can destroy structures and enemies by shooting rapid-fire eyeballs and vomit at them. Enemies include zombie snipers, zeppelins and lava monsters. The player can upgrade their firepower by rescuing zombie hostages that leap out of structures when destroyed.
The player starts every level with a full life bar of eight units (displayed as mini Namakubi heads at the bottom of the screen), and as the player gets hit, the life bar decreases. When it is down to one bar remaining, the music changes to a dramatic theme. The game ends when the player loses all eight units of the life bar or is crushed by the scrolling of the screen. However, the player can regenerate some of their life by defeating enemies and structures. In addition, the player gets six (increasing by one for every stage section completed, up to a maximum of nine) continues to beat the game.
Zombie Nation features two difficulty levels, easy and hard. The game also allows the player, like in the Mega Man series, to select any stage at will. Once a stage is selected the following stages will be played sequentially cycling from stage 4 back to 1. The objective is to clear all four stages and then destroy the final boss, Darc Seed.

## Story

The plot of Zombie Nation takes place in 1999, when a meteor known as "Darc Seed" (Eva in the Japanese version) crashes in the Nevada desert. Darc Seed/Eva then shoots magnetic rays and turns the people of the United States into zombies. Darc Seed/Eva also brings the Statue of Liberty to life to follow its commands. The magnetic rays also allow Darc Seed/Eva to control many deadly weapons, including the most powerful weapon of all—the legendary samurai sword Shura.
The head of the samurai Namakubi hears of Shura falling into Darc Seed's clutches. He then heads to the United States to destroy Darc Seed, free the American people from the looming zombification and reclaim the samurai sword Shura.

## Regional differences

The game was first released in Japan under the name Abarenbou Tengu on December 14, 1990. The US version was released a month later. As both versions only have differences between the sprites, with the Japanese version having a tengu mask belonging to Japanese folklore, the US version has major graphical and story changes, replacing the tengu mask with the decapitated samurai head. Aside from the differences, both games are practically identical, with the Japanese version having only a few major differences:
* In Abarenbou Tengu, the player must obtain the rapid fire ability. In Zombie Nation, the player starts with it.
* The main character's sprite is not that of the flying samurai head, Namakubi, but that of a Japanese konoha tengu head. The title screen is different, with the tengu's head being incorporated into it.
* The boss of Round I is an evil Statue of Liberty in both games but with a slightly different sprite; instead of being green with snakes in place of its crown in Zombie Nation, it's red and has a normal crown.

## Reception

Review scores :
| Publication | Score |
| Defunct Games | B |
| Dragon | |
| GamePro | 4.6/5 |
| Nintendo Power | 3.15 |
| The Video Game Critic | B+ |
The St. Petersburg Times tied the game with Splatterhouse 2 as the tenth-best video game of 1992. Mashable, in ranking Zombie Nation the second-weirdest video game of all time, claimed it "brings the side-scrolling shooter genre to a weird and gross new height. As challenging as it is confusing, the high point of this game is the chance to take down an animated, evil Statue of Liberty."
On the other hand, the Japanese version is criticized due to its difficulty and gameplay, and considered a kuso-gē (クソゲー, lit. "crap game"). However, both versions of the game are considered a cult hit among gamers.
