The game starts when Herbert attacks the EPF's main computer. While doing so, Gary attempts to track the location of Herbert's hideout, and the player needs to buy gary enough time by stopping all virus enemies' waves. Gary finds out that Herbert's location is somewhere in the mountains, and in the end of the level, his exact location is revealed- the Toughest Mountain.

By finding the location of herbert's hideout, the EPF planned to stop further attempts by Herbert to take over the island. Gary used the Air Conditioner 3000 to blast Herbert's hideout with cold air, and thereby made him hibernate. During the Great Snow Race, EPF agents infiltrated into Herbert's base, and constructed a cage to make sure that he doesn't escape.
