Unlocking every secret achievement in Holo vs Robo represents one of the most challenging yet rewarding experiences for completionist players. Unlike regular achievements that naturally appear through story progression, secret achievements require specific actions, hidden mechanics, or unusual win conditions that the game never explains directly. Based on my extensive research and hands-on experience, I’ve compiled this comprehensive guide covering all confirmed secret achievements with detailed unlock methods and proven strategies.

How Secret Achievements Work in 2026?

Secret achievements in Holo vs Robo remain hidden from your achievement list until unlocked. They’re typically tied to:

  • Hidden stages and areas
  • Character-specific mechanics and interactions
  • End-of-stage board states
  • Extremely long-term actions
  • Unusual win conditions

All achievements listed here are confirmed complete based on in-game tracking and Steam achievement data, verified through multiple sources including official game channels and community testing.

Complete Secret Achievement Guide

1. Madman – Beat the Madhouse

The Madhouse is a hidden stage accessible from the story map.

How to unlock:

  • Hover your cursor above the island area just above Stage 2-4
  • A hidden node labeled “Madhouse” will appear
  • Enter and clear the stage

Pro Tips:

  • Ollie provides massive cheer generation in this stage
  • Cheer is effectively unlimited, so use high-cost attackers freely
  • Shion excels here due to her multi-lane and flying enemy coverage
  • Aki is expendable but helps speed up clears

Strategy: Don’t hold back on expensive units – the unlimited cheer generation means you can field your strongest team without resource constraints.

2. Excuse Me – Reap 10 Enemies With One Calli

This achievement requires precise timing and character positioning.

How to unlock:

  • Enter Stage 1-5
  • Bring: Wall unit, Fauna, Moona, and Calli
  • Wait until mid-stage when enemies are grouped
  • Place Moona in the middle lane
  • Activate Calli at the perfect timing to reap at least 10 enemies

Critical Tips:

  • Timing matters more than raw damage
  • Wait for enemy clustering before activating
  • Moona’s positioning is crucial for enemy grouping

Common Mistake: Activating Calli too early when enemies aren’t properly grouped. Patience is key!

3. Monday Blues – Destroy 20+ A-chan Robos With One Kanade

This achievement requires specific enemy types and perfect timing.

How to unlock:

  • Must be completed on Stage 1-5
  • The stage must spawn A-chan Robos (not guaranteed every run)
  • Bring Kanade and support units
  • Trigger Kanade’s skill once enough A-chan Robos are present (20+)

Important Notes:

  • Cannot be unlocked on stages without A-chan Robos
  • May require multiple attempts due to enemy spawn RNG
  • Support units help keep Kanade alive while waiting for the right moment

4. Doomed Yuri – Defeat Nerissa-Bot Using ERB

A character-specific achievement that showcases ERB’s unique capabilities.

How to unlock:

  • Earliest Nerissa-bot appearance is Stage 2-4
  • ERB can solo Nerissa-bot with correct positioning
  • Play the stage normally with ERB as your main damage dealer

Critical Strategy:

  • Do not leave empty lanes, as Vivi-bot can instantly cause a loss
  • Position ERB carefully to maximize damage output
  • Use other units minimally to focus on ERB’s contribution

5. Evac – Move a Low HP Marine Using Subaru

This achievement leverages Marine’s unique passive mechanic.

How to unlock:

  • Deploy Marine as a wall unit
  • Allow her HP to drop significantly (but not to zero)
  • Use Subaru to reposition Marine into the backline while she’s at low HP

Mechanics Explained:

  • Marine gains a damage bonus at low HP
  • Moving her with Subaru triggers this bonus and unlocks the achievement
  • Timing is crucial – Marine must be low HP but still alive

6. Barren Glory – Beat a Level With No Holodolls Remaining

A risky achievement that requires careful balance.

How to unlock:

  • Allow all your holodolls to be removed from the field
  • Complete the stage afterward

Safety Tips:

  • Don’t accidentally lose by allowing Robos into empty lanes
  • Monitor Vivi-bot jumps carefully
  • Consider using single-use dolls for the final wave

Strategy: Clear most enemies first, then sacrifice your units strategically before the final wave.

7. On the Brink – Beat a Level With No Yagoo Heads Left

Similar to Barren Glory but focused on Yagoo heads.

How to unlock:

  • Allow Robos to destroy all Yagoo heads
  • Clear the stage afterward without losing

Easier Method:

  • Best attempted in shorter or early-game stages
  • Less risky than Barren Glory since Yagoo heads are defensive structures

8. Perfect Placement – Win With a Fully Symmetrical Board

This achievement has an easy exploit method.

How to unlock (Easy Method):

  • Near the end of any stage, scoop up all your dolls
  • Place a single Sana in the center
  • Clear the final wave

For Final Boss:

  • Leave only the middle row populated
  • Finish the boss using single-use dolls
  • As long as other rows are empty, symmetry still counts

9. Cheerleading Squad – Store 5,000 Cheer in One Level

Perfect for AFK progression.

How to unlock (AFK Strategy):

  • Enter Story Stage 1-1
  • Use only Nodoka and Fauna
  • Let the stage run until cheer accumulates naturally

Alternative Method:

  • Late-game A-chan makes this achievement much easier
  • Can be combined with other objectives for efficiency

10. Luckmaster – Win a Holodoll Race

The game’s only purely luck-based achievement.

How to access:

  • Click your coin count on the title screen
  • Select the “Horse Race Test”

Tips:

  • Exit and re-enter until races have fewer participants
  • Watch races until the end – unexpected upsets do happen
  • No skill involved, pure RNG

11. Do You Remember – Headpat Gigi 24,921 Times

The most notorious achievement in the game.

How it works:

  • Headpat Gigi a total of 24,921 times
  • Progress is saved automatically
  • You can stop and continue later

Strategy:

  • No shortcut exists – must be done manually
  • Break it into multiple sessions
  • Consider doing this while watching videos or listening to music

12. Marathon Master – Beat Marathon Mode

Unlocked after completing Story Mode.

Tips for clearing Marathon:

  • You can restart a stage even after losing a doll
  • Avoid Ollie in this mode (cheer generation isn’t optimal)
  • Start with Nodoka and Fauna for early cheer generation

Recommended Setup:

  • Use Subaru to reposition Nodoka as needed
  • Finish cheer generation with A-chan
  • Strong setup: 3 A-chan and 2 Nodoka in one column

Advanced Strategies & Pro Tips

Resource Management

  • Focus on one achievement at a time to avoid confusion
  • Some achievements can be combined efficiently
  • Save the grind-heavy achievements (like Do You Remember) for last

Character Synergies

  • Certain character combinations make achievements easier
  • ERB’s solo capability is unique and valuable
  • A-chan’s late-game cheer generation is game-changing

Stage Selection

  • Not all stages are suitable for all achievements
  • Early stages are safer for risky achievements
  • Some achievements require specific enemy spawns

Common Mistakes to Avoid

  1. Rushing through achievements – Take time to understand requirements
  2. Ignoring character positioning – Many achievements depend on precise placement
  3. Not checking enemy types – Some achievements require specific enemies
  4. Giving up too early – Some achievements require multiple attempts due to RNG
