This gamepass will give you access to the energy core control where you can activate a self-destruct sequence to blow the whole game up! You will unlock the "Core Access" head title, a neon orange chat color and 60% more money for escaping the meltdown. The maximum payout for escaping is 200 billion. The energy core is located under the lobby, take the stairs from the lobby down to the floor level, then walk to the other side of the stair exit and you'll see a ladder leading down to the energy core.
