Prepare strong Rex-type tames, high-quality armor and weapons, healing supplies, and coordinated teammates, or use a carefully bred solo army with a Yutyrannus. Progress through successive arena stages by defeating corrupted creatures and Avatars, collecting their data fragments, and using them at the consoles to advance. In the final stage, deactivate the terminals to lower the Controller’s shields while surviving its summoned enemies and disabling laser attacks, then damage it until defeated.
