The AI of "Dune II" was one of the first used in RTS games, and while better than that of "Herzog Zwei", it has various drawbacks. Examples include only attacking the side of the player's base facing its own, general inability to perform flanking maneuvers, and not rebuilding defenses. Recent research into the game's engine by fans revealed that the AI is in fact capable of more advanced strategy, but that a large part of these capabilities is unused due to consistently repeated errors in all of the game's mission scripts.
