How to Unlock Roberto in Megabonk: Complete Overview

Before diving into the step-by-step process, let me break down exactly what you’re getting into. Unlocking Roberto is a three-stage challenge that tests your understanding of Megabonk’s progression system:

StageMain ObjectiveKey RequirementsEstimated Time
Stage 1Unlock Graveyard MapCalcium character, Desert Tier 2, defeat Undead Boss30-60 minutes
Stage 2Unlock Scythe Weapon4 Crypt Keys, defeat Big Bob OR Spooky Steve45-90 minutes
Stage 3Unlock Roberto CharacterScythe already unlocked, defeat Spooky Steve60-120 minutes

This guide will take you through each stage in detail, with multiple strategies for different playstyles and skill levels. Let’s get started!

Prerequisites: What You Need Before Starting

Before you can even think about unlocking Roberto, you need to ensure you have access to the required content. Many players get stuck here because they haven’t progressed far enough in the base game.

Required Unlocks:

  • Calcium Character: Unlock by killing 1,000 Skeletons
  • Desert Map: Complete Forest Tier 1 to unlock CL4NK, then finish Forest Tier 2 as CL4NK
  • Desert Tier 2: Complete Desert Tier 1 first
  • Basic Game Knowledge: Understanding of weapon upgrades, tome mechanics, and boss patterns

If you’re missing any of these prerequisites, focus on unlocking them first. The Desert Tier 2 requirement is particularly important—you cannot access the Graveyard unlock quest without it.

Stage 1: Unlocking the Graveyard Map

The Graveyard serves as the foundation for everything else in the Spooky Update. This third map is where you’ll find both the Scythe weapon and Roberto himself, but you need to unlock it first.

Step-by-Step Graveyard Unlock:

Step 1: Start the Right Run

  • Select Calcium as your character (non-negotiable)
  • Choose Desert Tier 2 difficulty
  • Graves only spawn when playing as Calcium, so don’t waste time with other characters

Step 2: Find and Disturb Four Graves

  • Explore the Desert map until you find the first grave (appears as a coffin-style object)
  • Interact with it using the “Disturb Grave” prompt
  • A White Ghost will spawn—defeat it quickly
  • After defeating each ghost, a yellow/white marker appears showing the next grave location

Step 3: Defeat All Four Ghosts You’ll face four different ghosts in sequence:

  1. White Ghost: Easiest, basic projectile patterns
  2. Black Ghost: Moderate difficulty, hits harder
  3. Purple Ghost: Mid-run boss check, requires stable build
  4. Red Ghost: Final mini-boss, ensure your build is ready

Pro Tip: Use Calcium’s high movement speed to kite these ghosts. Circle around them while avoiding their projectile patterns. Don’t activate any Greed Shrines during this process—they’ll make the final boss fight much harder.

Step 4: Summon and Defeat Calcium’s Dad

  • After defeating the Red Ghost, follow the final marker to a golden skeleton statue
  • Interact with the statue to summon the Undead Boss (Calcium’s Dad)
  • This boss shares attack patterns with the Scorpionussy boss:
    • Raises damaging rocks from the ground
    • Fires a red laser that sweeps across the arena
    • Teleports around the arena

Strategy for Calcium’s Dad:

  • Keep moving in circles around the boss
  • Step out of telegraphed rock spawn areas
  • Dodge the red laser by maintaining lateral movement
  • Focus on damage upgrades rather than survivability
  • On lower difficulties, his health is around tens of thousands HP

Step 5: Complete the Unlock

  • Once Calcium’s Dad is defeated, a chest drops
  • The Graveyard map unlocks permanently for all characters
  • You don’t need to survive the rest of the run—the unlock is instant

Stage 2: Unlocking the Scythe Weapon

Roberto’s signature weapon, the Scythe, must be unlocked before he becomes available. This stage takes place in the newly unlocked Graveyard map and offers two different paths to success.

Understanding the Scythe Unlock

The Scythe is a 360-degree melee weapon with excellent crowd control and scaling potential. It’s Roberto’s starting weapon, making it essential for his unlock process. You have two methods to unlock it:

Method A: Defeat Big Bob (Recommended)

Step 1: Enter the Crypt

  • Start a run on the Graveyard map with any character (no restrictions now)
  • Locate and enter the Crypt area (usually marked on the map)

Step 2: Collect Four Crypt Keys

  • Search for coffins scattered throughout the Crypt
  • Each coffin you activate spawns a mini-boss
  • Defeat the boss to receive a Crypt Key
  • Repeat until you have all four keys

Step 3: Summon and Defeat Big Bob

  • Use the four Crypt Keys to access Big Bob’s arena
  • Big Bob has a unique light mechanic similar to the Forest boss:
    • Unlock lamps to make him vulnerable
    • Stay inside light sources during dark phases
    • Instant death if caught outside light during dark waves

Big Boss Fight Strategy:

  • Prioritize unlocking lamps quickly
  • Stay mobile but always near a light source
  • Use weapons with good crowd control
  • Focus damage during vulnerability phases
  • Avoid greed—survivability is more important than speed

Method B: Defeat Spooky Steve (Alternative)

Step 1: Enter the Crypt

  • Same as Method A—start a Graveyard run and enter the Crypt

Step 2: Intentionally Fail to Escape

  • Do NOT collect all four Crypt Keys
  • Do NOT escape the Crypt before the timer runs out
  • Let the timer expire or fail the escape objective

Step 3: Face Spooky Steve

  • Spooky Steve spawns automatically when you fail to escape
  • This boss has an enormous health pool: 340.3Ud
  • The fight tests sustained DPS rather than complex mechanics

Spooky Steve Strategy:

  • Build for maximum damage and attack speed
  • Use area-of-effect weapons for consistent DPS
  • Position yourself to minimize movement
  • The fight is long—focus on sustainable damage output
  • Consider using Megachad for this fight (more on builds later)

Which Method Should You Choose?

MethodProsConsBest For
Big BobMore controlled fight, predictable mechanicsRequires key collection, light mechanicPlayers who prefer strategic fights
Spooky SteveNo key collection needed, straightforwardMassive health pool, long fightHigh-DPS builds, experienced players

My Recommendation: Most players should go for Big Bob first. The fight is more engaging and teaches important mechanics for the Graveyard map. Save Spooky Steve for when you’re specifically unlocking Roberto.

Stage 3: Unlocking Roberto Character

This is the final stage where you’ll add Roberto to your permanent character roster. The process depends on which method you used to unlock the Scythe.

If You Used Big Bob Method:

Step 1: Ensure Scythe is Unlocked

  • Verify that the Scythe appears in your weapon selection
  • If not, complete the Big Bob fight first

Step 2: Start a New Graveyard Run

  • Choose any character you’re comfortable with
  • Megachad and well-built Calcium are popular choices
  • Progress through the map normally

Step 3: Trigger Spooky Steve

  • Enter the Crypt but intentionally fail to escape
  • Let the timer expire or don’t collect all keys
  • Spooky Steve will spawn automatically

Step 4: Defeat Spooky Steve

  • Use a high-DPS build (detailed build section below)
  • The fight is identical to Method B from Stage 2
  • Focus on sustained damage over the long health bar

Step 5: Roberto Unlocks

  • Once Spooky Steve is defeated, Roberto unlocks permanently
  • You can die afterward without losing the unlock
  • Roberto appears in your character selection screen

If You Used Spooky Steve Method:

Good news! If you already defeated Spooky Steve to unlock the Scythe, Roberto should already be unlocked. Check your character selection screen—he should be available immediately.

Roberto: Character Analysis and Strengths

Now that you’ve unlocked Roberto, let’s understand why he’s worth all this effort. Roberto isn’t just another character—he’s potentially game-changing with his unique mechanics.

Roberto’s Core Abilities:

Scythe (Starter Weapon)

  • 360-degree circular attack pattern
  • Hits multiple enemies per swing
  • Charges stronger attack after killing Elite enemies
  • Scales exceptionally well with Size, Quantity, and Damage upgrades
  • Limited base range but compensated by other abilities

Hoarder Passive (Game-Changer)

  • Automatically spawns a free chest every 60 seconds
  • Interval changes to 120 seconds at higher levels
  • Provides constant stream of items and upgrades
  • Makes Luck and item quality incredibly important
  • Enables faster power scaling than any other character

Float Ability

  • Roberto can “float” or bunny-hop across the map
  • Provides excellent mobility and positioning control
  • Allows unique aerial playstyle
  • Compensates for low base health with superior positioning

Why Roberto is Meta-Defining:

AspectImpactMeta Relevance

AOE Coverage360-degree damageExcellent for wave management

Roberto’s strength lies in his ability to snowball power faster than any other character. The combination of free chests, strong AOE coverage, and superior mobility makes him exceptionally strong in both early-game survival and late-game dominance.

Best Builds for Unlocking Roberto

To make your Roberto unlock journey smoother, here are the most effective builds for each major challenge:

Big Boss Fight Build (Recommended)

Weapons:

  • Aura: Creates persistent damage zone, excellent for crowd control
  • Dexecutioner: High single-target damage for boss phases
  • Frostwalker: Provides crowd control and slow effects
  • Black Hole: Groups enemies for efficient clearing

Tomes:

  • Size Tome: Increases Aura and Scythe coverage
  • XP Tome: Faster leveling for more upgrades
  • Cooldown Tome: More frequent ability usage
  • Evasion Tome: Improved survivability

Items:

  • Moldy Cheese: Significant damage boost
  • Boss Buster: Extra damage against bosses
  • Big Bonk: Area damage enhancement
  • Beefy Ring: Health and damage scaling
  • Gym Sauce: Overall damage increase
  • Ghost: Defensive capabilities

Spooky Steve DPS Build (Essential)

Weapons:

  • Dexecutioner: Primary damage source
  • Aura: Consistent AOE damage
  • Frostwalker: Crowd control for adds
  • Black Hole: Enemy grouping

Tomes:

  • XP Tome: Critical for Megachad’s Flex uptime

Why This Works: Megachad’s Flex ability provides temporary invincibility when leveling up. With constant XP from the XP Tome and frequent chest openings, you can maintain near-constant uptime on this buff, making the Spooky Steve fight much safer.

Common Mistakes to Avoid

After helping dozens of players unlock Roberto, I’ve identified these common pitfalls that can waste hours of your time:

Mistake 1: Wrong Character for Graveyard Unlock

  • Problem: Using any character other than Calcium
  • Solution: Graves ONLY spawn with Calcium—don’t waste time with other characters
  • Impact: Complete failure to start the unlock chain

Mistake 2: Greed Shrine Activation

  • Problem: Activating Greed Shrines during boss fights
  • Solution: Avoid them entirely during unlock quests
  • Impact: Significantly harder boss fights with no meaningful benefit

Mistake 3: Wrong Build Focus for Spooky Steve

  • Problem: Building for survivability over DPS
  • Solution: Spooky Steve is a DPS check—focus entirely on damage
  • Impact: Fight becomes impossibly long and difficult

Mistake 4: Not Understanding Light Mechanics

  • Problem: Ignoring lamp mechanics in Big Bob fight
  • Solution: Prioritize lamp activation and stay in light
  • Impact: Instant death during dark phases

Mistake 5: Poor Resource Management

  • Problem: Wasting resources on wrong upgrades
  • Solution: Focus on damage, attack speed, and cooldown reduction
  • Impact: Insufficient DPS for timed challenges

Roberto’s Endgame Potential

Once you’ve unlocked Roberto, his true potential shines in extended runs and high-difficulty content. Here’s why he’s considered top-tier:

Snowball Potential

Roberto’s Hoarder passive creates exponential growth:

  • More chests → Better items → More survivability → Longer runs → Even more chests
  • This feedback loop makes him exceptionally strong in marathon sessions

Build Flexibility

Despite starting with the Scythe, Roberto excels with various weapon combinations:

  • Melee Focus: Scythe + Aura + Size scaling
  • Ranged Hybrid: Scythe + Lightning Staff/Blood Magic
  • Execute Build: Scythe + Dexecutioner for elite/boss deletion

Competitive Viability

In the current meta (2026), Roberto dominates several categories:

  • Fastest clear times on lower difficulties
  • Highest potential scores in extended runs
  • Most consistent performance across varied scenarios

FAQ

Q: Can I unlock Roberto without the Graveyard map?

A: Absolutely not. The Graveyard map is a mandatory prerequisite, and you can only unlock it by defeating Calcium’s Dad in a Desert Tier 2 run while playing as Calcium. There are no shortcuts or alternative methods.

Q: Do I have to defeat both Big Bob and Spooky Steve?

A: No, you only need to defeat ONE of them to unlock the Scythe weapon. However, you WILL need to defeat Spooky Steve eventually to unlock Roberto himself, unless you happened to defeat him first for the Scythe unlock.

Q: Which boss is easier for unlocking the Scythe?

A: Big Bob is generally considered the more straightforward method. While he has mechanics to learn (the light system), his health pool is manageable and the fight is more engaging. Spooky Steve has a massive health pool (340.3Ud) and is essentially a DPS check that can take 10+ minutes even with good builds.

Q: What is Roberto’s main strength?

A: Roberto’s strength lies in his Hoarder passive, which generates additional free chests throughout your run. This provides a massive economic and item advantage, allowing for faster power scaling and access to high-tier items much earlier than other characters.

Q: Can I use any character to unlock the Scythe and Roberto?

A: Yes, but ONLY after the Graveyard is unlocked. The initial Graveyard unlock MUST be done with the Calcium character. Once the Graveyard is available, any character can be used for the Scythe and Roberto unlock process.

Q: How do I find the Graves in Desert Tier 2?

A: Graves spawn in random locations and only appear when you start the run with Calcium. Once you find and defeat the first grave (White Ghost), a yellow exclamation mark appears on your screen showing the location of the next grave. Follow these markers sequentially.

Q: How do I quickly defeat Spooky Steve?

A: Focus entirely on Damage and Attack Speed. Faster hits and high DPS are the only ways to kill Spooky Steve efficiently. Use the Megachad build with XP Tome for near-constant Flex uptime, and prioritize Dexecutioner upgrades. The fight is long—prepare for a 10+ minute battle even with optimal builds.

Q: Is Roberto worth unlocking in Megabonk?

A: Absolutely, yes. Roberto is considered one of the strongest characters in the current Megabonk meta. His item-focused passive provides consistent advantages throughout runs, and his mobility with float makes him exceptionally versatile. He’s particularly strong for players who enjoy aggressive, high-mobility playstyles.

Q: What happens if I die during a boss fight?

A: For progression unlocks (Graveyard map, Scythe, Roberto), the unlock is granted as soon as the boss dies. You don’t need to survive the rest of the run. However, dying means you’ll need to start a new run to attempt the next stage of the unlock process.

Q: Can I unlock everything in one run?

A: It’s theoretically possible but extremely difficult. You would need to: 1) Unlock Graveyard with Calcium, 2) Immediately progress to collect Crypt Keys and defeat Big Bob, 3) Then trigger and defeat Spooky Steve in the same run. This requires an exceptionally strong build and perfect execution.

Conclusion

Unlocking Roberto in Megabonk’s Spooky Update is undoubtedly one of the most challenging but rewarding progression chains in the game. You’ve learned how to navigate the Desert as Calcium, master the Graveyard’s mechanics, and defeat some of the toughest bosses in the game.

Remember these key takeaways:

  • Patience is crucial: This unlock process takes time and multiple attempts
  • Build appropriately: Each challenge requires different strategies
  • Learn from failures: Each attempt teaches you more about boss patterns
  • Roberto is worth it: His unique abilities make him a top-tier character

Now that you have this comprehensive guide, you’re equipped with everything needed to add Roberto to your roster. The journey may be challenging, but the reward a character with game-changing potential—makes every boss fight worth the effort.
