You're an aged war veteran called Zed Pelin. A malevolent empire has begun to attack a small independent planet. You have to stop the evil terrorist group in its tracks.

Your aim in this action-packed title, then, is to aid a resistance movement by transporting passengers and cargo, protecting valuable targets, and taking down enemy combatants.

You do this across 20 hand-illustrated levels that are spread across dark forests, even darker mines, and snowy mountains.
