The crew of the starship Cyber Knight is on a mission to return home after being flung across the galaxy by their jump drive. The ship is badly damaged, and only 26 survivors remain, including six qualified combatants who pilot giant mechanized suits called Modules. These survivors land on the planet Farworld, which is under attack by mechanical aliens known as Berserkers.
The game Cyber Knight is an RPG that takes place in a top-down view for movement and side-view for combat sequences. Players can travel between stars, scanning worlds for information, and land on planets to explore and complete quests. The six Modules can be upgraded with analysis of "NeoParts" left behind by defeated Berserkers, unlocking new statistics and weapons. Combat takes place in turn-based battles on a 6x6 squares field, where players position the Modules to attack enemies using various melee and long-ranged attacks.
The game features a unique system where each Module has two sets of hitpoints, one for the pilot and one for the module itself. Players must manage their resources carefully, as healing kits and options can be restored by returning to the Cyber Knight 's lab. With six different Modules and pilots, each with unique skills, players must use strategy to overcome the challenges of the alien galaxy.
