Given the enemy's ability to open portals freely and move between planets, Zack faced a difficult challenge in tracking them down. The adversaries' tactical advantage of mobility meant they could evade detection and strike from unexpected locations. This flexibility in their operations made it difficult for Zack to predict their movements or establish a fixed strategy to confront them.
The realization that the enemy could operate across multiple planets added another layer of complexity to Zack's mission. It meant that his efforts to eliminate the threat were not confined to a single location but required a broad, multi-dimensional approach. Tracking and intercepting the enemy's movements became a strategic puzzle, demanding Zack's utmost focus and resourcefulness to outmaneuver their elusive tactics.
