With the Power On you'll just need to get 2500 more points in order to get through the last two doors in your way.

Before you do this you might want to either upgrade your current weapon or spin the Mystery Box a few times just to get better equipped.
Upon opening the second door a blue orb will appear and spawn in an Oni. To help take this out concentrate your fire on his head and avoid his close range attacks.


Once killed he will drop the Shogun's Hanko along with a killstreak.

Pick this up and interact with door in the room to apply the Shogun's Hanko.

This will open up the next area where you'll need to feed souls to the World Seed.


After completing the World Seed event, the Pack-a-Punch machine rises from the center of the Sanctum, becoming permanently available for the remainder of the match.
Strategy:
- Focus exclusively on marked enemies.
- Train regular zombies away from the center.
- Use grenades or field upgrades if you become overwhelmed.
Once enough marked zombies have been defeated, the World Seed reacts and transforms.
