Part 9

Head to the sewer gate with 10 blue minions. Consider setting up a guard marker (a designated safe spot for minions) on land before moving the pillar blocking the gate.

Move the pillar to reveal a large number of zombies. Lure them to your minions on shore to defeat them. Alternatively, run back to the tower gate and then to Heaven's Peak; the zombies may disappear upon your return.

Return to Mellow Hills. Follow the path past the Spree entrance towards the slave camps, to the brown minion spawn pit next to the blood pit.

Find a hidden path behind the brown spawn pit. Follow it to the shore and send blue minions to retrieve a tower object.

Bring the tower object back to create a bridge, allowing for more minion control to a waypoint (a marker on your map you've manually placed as a destination).

Head back to Heaven's Peak to the sewer entrance.

In the Understreets, proceed up the path until you see two stairways, one left and one right.

The right path leads to loot and a brown minion spawn pit. The left path leads to many zombies.

You can slowly kill the zombies with your overlord (a powerful minion), with health regeneration armor being very helpful.

A better strategy involves taking the right path to the loot area with blue and brown spawn pits. Command a brown minion out of its hole; it will drown. If you are quick, or have a blue minion waiting in the water, command the blues to grab the drowned brown minion and carry it back to land to revive it. Repeat this to build an army. A pipe between the staircases allows your new army to cross and deal with the zombies.

Another method: send blue minions down the pipe onto a small patch of land and set a guard point. Summon brown minions slowly, and the blues will save them when they drown.

Once the zombies are dead, proceed around the path to find barrels and chests. Continue until you see brown and blue spawning pits.

Boombo birds and eggs guard a red spoke. Leave it for now.

Grab some brown and blue minions and turn back towards a door blocked by mushrooms and barrels. Go through, around the path, and kill the zombies.

You will find the red wheel and need 3 spokes. Loot the platform you are on.

Return to the previous room with the birds. Set up guard markers. Send a blue minion to get an egg, bring it back, and have your brown minions kill the birds while blues revive them.

Alternatively, use a fire spell on the birds to defeat them quickly without needing eggs or losing minions.

Retrieve the first red spoke.

From the red wheel, head down the stairs and turn left. Set up a guard marker and break down a barrier in the water.

Lure zombies to your minions, then head up the next set of stairs. Kill bugs, loot, and break down a door.

Kill zombie priests and break the barrier to the right. Grab the second red spoke and return to the room with the wheel.

Send your minions to turn the wheel in this room. Head through the opened door and to the right, killing bugs.

Leave your minions and enter the water. Lure zombies to your minions, then head back. To the right is an area to loot.

Head back down the water path and around to find bugs and loot. Go up the stairs to find a red spawning pit.

Grab a red minion and break the fire barrier to your horde.

Return to the red wheel with red and blue minions. To the right of the wheel is a pipe. Sweep some minions across it.

Set up a guard marker of red and blue minions for resurrection. Sweep them across the pipe to shoot zombie priests across the water and zombies on the floor.

Go to the spot where you break the barrier leading to the zombies. Take that path, killing zombies, to reach the platform with the final red spoke.

Have a blue minion grab the final red spoke and return it to the red wheel. Turn the wheel to proceed.

Go through the gate and find a member of the Silent Order. Loot the area and head left.

Return to town. Loot the area and keep only blue minions. Head to the back and down some stairs.

Kill bugs for blue lifeforce if desired. Follow the path up more stairs to a blue spawn pit.

Attempting to sweep minions to turn a wheel will summon a water serpent.

Take a full battalion of blue minions to turn the wheel before the serpent attacks.

Walk through the opened gate. A brown spawn pit is ahead.

To defeat the hydra, position blues near the water for resurrection while you and brown minions attack from a higher platform when it attacks. Alternatively, attack it yourself, which takes a long time but preserves minions. A green spawning pit is in the zombie room if you prefer using greens. Kill the hydra.

Leave the three giant sacks of cash for now.
