How to Unlock the Secret Madhouse Stage?
Madhouse doesn’t appear on the main Story Mode path, which explains why many players miss this hidden gem entirely. To access this secret stage:
Contents
- Navigate to Story Mode from the main menu
- Locate Stage 2-4 on the island map
- Move your cursor to the top area directly above Stage 2-4
- Wait for the hidden stage “Madhouse” to appear
- Click to enter like any other story stage
The stage remains permanently unlocked once discovered, so you can retry it as many times as needed without repeating the discovery process. This clever hiding spot has kept the Madhouse stage secret from the majority of players, contributing to the achievement’s rarity.
What Makes Madhouse Unique?
Unlike any other stage in Holo vs Robo, Madhouse completely changes the game’s core mechanics through one major twist: unlimited cheer generation provided by Kureiji Ollie. This fundamental change transforms the stage from a resource management challenge into a pure test of strategy and unit placement.
Key Differences from Regular Stages:
- Infinite Cheer: Ollie generates cheer at an absurd rate, making resource management irrelevant
- No Cost Constraints: You can deploy high-cost units without hesitation
- Focus Shift: Success depends on unit placement and replacement speed rather than economy
- Aggressive Playstyle: The stage rewards spamming powerful attackers rather than conservative play
This unlimited resource environment makes Madhouse one of the most enjoyable stages once you understand its mechanics. The removal of economic pressure allows you to experiment with different unit combinations and strategies that would be impossible in regular stages.
Best Unit Setup for Madhouse
Given the unlimited cheer mechanic, your unit selection should prioritize raw damage output and lane coverage over cost efficiency. Based on extensive testing and community feedback, here are the optimal units for Madhouse:
Primary Damage Dealer: Shion
Shion stands out as the premier choice for Madhouse due to her unique abilities:
- Cross-lane attacking: Can hit enemies in adjacent lanes
- Anti-air capabilities: Effectively deals with flying Robos
- Stacking potential: Multiple Shions create devastating damage zones
- Range advantage: Safely attacks from distance
Strategy: Stack 2-3 Shions in key lanes to control multiple paths simultaneously. Her ability to attack outside her lane makes her invaluable for covering weak points and handling unexpected enemy movements.
Alternative: Botan
If you haven’t leveled Shion sufficiently, Botan serves as an excellent alternative:
- Strong single-lane dominance: Excels in focused lane control
- High damage output: Comparable effectiveness to Shion in straight lanes
- Reliable performance: Consistent damage without complex positioning
Strategy: Place Botan in lanes where you need concentrated firepower. While she lacks Shion’s cross-lane capabilities, her raw damage makes her more than capable of handling most threats.
Support Unit: Aki
Aki plays a crucial, though sacrificial, role in your Madhouse strategy:
- Robo specialist: Accelerates Robo destruction
- Disposable nature: Expected to die frequently
- Speed focus: Designed for quick deployment and replacement
- Low cost: Easy to replace when lost
Strategy: Deploy Aki aggressively to speed up Robo elimination. Don’t worry about her survival – with unlimited cheer, you can instantly replace her when she falls. Treat her as expendable acceleration rather than a permanent fixture.
Handling Yagoobots: The Main Threat
Yagoobots represent the primary challenge in Madhouse due to their unit removal ability. These dangerous enemies can instantly eliminate your placed units, creating gaps in your defense that Robos can exploit.
Effective Yagoobot Counter-Strategy:
- Constant Vigilance: Watch your unit placements continuously for losses
- Immediate Replacement: Redeploy fallen units the instant they’re removed
- Overstacking: Place extra units in critical lanes to absorb removal
- Priority Targeting: Focus fire on Yagoobots before they can remove key units
Since cheer is unlimited, don’t hesitate to overstack your defenses. Having backup units ready to replace lost ones is far more valuable than conserving resources in this stage.
Advanced Yagoobot Techniques:
- Bait Placement: Use expendable units like Aki to draw Yagoobot attention
- Recovery Positioning: Keep high-value units like Shion slightly back to avoid immediate targeting
- Wave Management: Save some cheer for emergency replacements during intense Yagoobot waves
General Tips for Beating Madhouse Easily
Master these fundamental principles to significantly reduce Madhouse’s difficulty:
Core Strategy Principles:
- Ignore Cheer Efficiency: Since cheer is unlimited, focus entirely on damage output
- Prioritize Coverage: Ensure all lanes have adequate protection rather than perfecting individual lanes
- Stack Attackers: Concentrate firepower rather than spreading units thin
- Instant Replacement: Never hesitate to redeploy units immediately after loss
- Robo Priority: Target Robos first to reduce overall pressure
Common Mistakes to Avoid:
- Resource Conservation: Don’t try to save cheer – it’s infinite
- Overthinking Placement: Quick, adequate placement beats slow, perfect placement
- Unit Attachment: Be willing to sacrifice units strategically
- Passive Defense: Maintain aggressive unit deployment throughout
Pro Tips for Consistent Victory:
- Pre-position Key Units: Have Shion or Botan ready in critical lanes before major waves
- Use Aki Liberally: Deploy Aki frequently to speed up Robo clearance
- Monitor Multiple Lanes: Don’t focus too heavily on single areas
- Adapt to Enemy Patterns: Adjust unit placement based on Robo movement patterns
- Maintain Pressure: Keep deploying units even when defense seems adequate
Getting the Madman Achievement
The Madman Achievement unlocks automatically upon successful completion of the Madhouse stage. There are no additional requirements, hidden objectives, or special conditions to meet – simply beating the stage is sufficient.
Achievement Details:
- Rarity: Very Rare (2.4% of players)
- Points: 815 EXP
- Category: Secret Achievement
- Unlock Condition: Beat the Madhouse stage
Once you clear the stage, the achievement notification will appear immediately. The achievement will remain unlocked even if you struggle with subsequent attempts, so don’t worry about maintaining consistency after your first victory.
Alternative Strategies and Unit Combinations
While the Shion/Botan + Aki combination represents the most reliable approach, several alternative strategies can also succeed in Madhouse:
High-Cost Attacker Spam:
Since cheer is unlimited, you can experiment with expensive units that would be impractical in regular stages:
- Multiple High-Damage Units: Stack various expensive attackers for overwhelming firepower
- Specialized Counters: Use situational units without worrying about cost
- Experimental Combinations: Test unusual unit synergies freely
Instant Unit Only Challenge:
Some players have successfully completed Madhouse using only instant-deployment units. This advanced strategy requires:
- Perfect Timing: Precise unit placement and replacement
- Wave Knowledge: Understanding enemy patterns for optimal deployment
- Quick Reflexes: Rapid response to unit losses
While more challenging, this approach demonstrates the stage’s flexibility and the power of unlimited resources.

Frequently Asked Questions
How do I find the Madhouse stage if I can’t see it?
Ensure you’re hovering your mouse directly above Stage 2-4 on the Story Mode map, not just near it. The stage only appears when your cursor is in the exact spot. Try moving your cursor slowly across the top area of the island until the hidden stage appears.
What’s the minimum team level needed for Madhouse?
While there’s no official level requirement, having Shion or Botan at least partially leveled significantly increases your success rate. Most players find success with units around level 3-5, but skilled players can complete it with lower-level units using perfect strategy.
Can I get the Madman Achievement in co-op mode?
The Madman Achievement is only awarded for single-player completion of the Madhouse stage. Co-op progress doesn’t count toward this specific achievement, though playing co-op can help you practice strategies.
Why is the Madman Achievement so rare?
With only 2.4% of players earning this achievement, its rarity comes from the stage’s hidden nature rather than extreme difficulty. Many players simply never discover the secret stage, and others may struggle with the unique mechanics without proper guidance.
What happens if I fail Madhouse multiple times?
Nothing negative occurs from repeated failures. The stage remains unlocked for unlimited attempts, and your progress toward the achievement isn’t affected. Each failure helps you learn enemy patterns and improve your strategy.
Are there any time limits or special conditions in Madhouse?
Madhouse follows standard stage rules with no time limits or special conditions beyond the unlimited cheer mechanic. Simply survive all enemy waves to complete the stage and unlock the achievement.
Can I use any units in Madhouse, or are some restricted?
All unlocked units are available for use in Madhouse. However, the unlimited cheer mechanic makes high-cost attackers particularly effective, while low-cost cheer generators become less valuable than in regular stages.
