After being defeated by Omnitron in the Pike Industrial Complex (the previous game), Haka and The Wraith returned with backup in the form of Legacy and Unity. Unfortunately, Omnitron had had time to perfect its sinister devices (aka playing on Advance). Despite a slow start for some, Unity popped out a pair of Raptor Bots early on. These did well, until an Experimental Mutagen popped out, and rats devoured some of Unity's golems. Bee Bot proved instrumental in destroying the Irradiated Cyclohexane Vat, which Omnitron was taking advantage of via Adaptive Plating Subroutine. Through Haka's Ground Pounding and Legacy's kiting, the heroes were able to wear down Omnitron. Omnitron made a miscalculation when it snuck up on Legacy, for it received a Back-Fist Strike, which defeated the rogue robot...for now.
