Ghost Blade HD is an improved edition of the top-down arcade shooter in a sci-fi setting. 10,000 years ago, an artificial intelligence named Shira was created, whose task is to ensure the protection of the inhabitants of Mars. As time passed, a certain error crept into the AI and it began to attack the Martian colonies. Unable to fight back against the crazed AI on his own, Mars asks for help. The Earth Defense Space Fleet is sent to destroy the Shire. He uses powerful lasers against the enemy to destroy them.
