How to Beat Madhouse & Get the Madman Achievement Holo vs Robo Guide

The Madman Achievement in Holo vs Robo is one of the most hidden challenges in the game, and many players don’t even realize the stage exists. Madhouse is a secret level tucked away inside Story Mode, and while it sounds intimidating, it’s actually one of the most fun stages once you understand its mechanics. This guide explains how to unlock Madhouse, what makes the stage special, and the best unit setup to clear it consistently.

How to Unlock the Secret Madhouse Stage

Madhouse does not appear directly on the Story Mode path, which is why many players miss it. To find it:

• Open Story Mode
• Go to the island with Stage 2-4
• Move your cursor to the top of the island above 2-4
• A hidden stage called Madhouse will appear

Once discovered, you can enter it like any other story stage.

Why Madhouse Is Different from Other Stages

What makes Madhouse unique is the massive cheer boost provided by Ollie. In this stage:

• Cheer generation is extremely high
• Cheer management is basically irrelevant
• You can spam high-cost attackers freely

This removes the usual resource pressure and turns the stage into a pure unit placement and survival challenge.

Best Unit Setup for Clearing Madhouse

Because cheer is unlimited, the goal is to overwhelm enemies with damage while replacing units that get destroyed.

Shion

• Can attack enemies outside her lane
• Can hit flying enemies
• Very strong when stacked
• Ideal main damage dealer

Stacking Shion allows you to control multiple lanes at once, making her one of the safest choices for this stage.

Botan

• Strong lane control
• Works well if you prefer single-lane dominance
• Can replace Shion if you don’t have her leveled

Both options work, but Shion’s range advantage gives her the edge.

Aki

• Helps take down Robos faster
• Expected to die often
• Used mainly for speed, not survival

Aki is not meant to stay alive long. Since cheer is infinite, losing her doesn’t matter. Just redeploy when needed.

How to Handle Yagoobots

Yagoobots are the main threat in Madhouse because they can remove your units.

Best approach:

• Constantly watch for unit losses
• Replace fallen units immediately
• Do not hesitate to overstack attackers

Since resources are unlimited, aggressive replacement is the key to winning.

General Tips for Beating Madhouse Easily

• Ignore cheer efficiency completely
• Prioritize raw damage and coverage
• Stack attackers instead of spreading them thin
• Replace units instantly when they get taken out
• Focus on Robos first to reduce pressure

Once you understand that the stage is designed around unlimited cheer, the difficulty drops significantly.

How to Get the Madman Achievement

After successfully clearing the Madhouse stage:

• The Madman Achievement unlocks automatically
• No extra objectives or conditions are required

Simply beating the stage is enough.

Madhouse in Holo vs Robo is a hidden gem that many players overlook. With unlimited cheer and a chaotic enemy lineup, it’s less about resource management and more about smart unit stacking and fast replacements. Using Shion or Botan as your main damage dealers and treating support units as disposable makes the stage far more manageable. Once cleared, you’ll earn the Madman Achievement and bragging rights for completing one of the game’s most secret challenges.
