Roberto Character	Automatic after Scythe unlock	N/A	Instant

Understanding the Prerequisites

Before you can even think about unlocking Roberto, you must first gain access to the Graveyard, the third map in Megabonk. This map is the cornerstone of the Spooky Update and the key to your entire unlocking journey. Many players make the mistake of trying to rush toward Roberto without properly preparing, but trust me – taking the time to understand each step will save you hours of frustration.

The Graveyard map isn’t available from the start, and for good reason. It’s home to some of the most challenging content in the game, including the bosses you’ll need to defeat to unlock both the Scythe weapon and Roberto himself. Let’s break down exactly how to access this crucial map.

Step 1: How to Unlock the Graveyard Map?

The Graveyard serves as your gateway to unlocking Roberto, and accessing it requires completing a specific questline with the Calcium character. This step is non-negotiable – you cannot skip it or use any other character for this initial unlock.

Detailed Graveyard Unlock Process

Start a Run with Calcium: Begin a new game using the Calcium character. This is the only character that can trigger the grave-disturbing mechanics needed for this quest.
Play in Desert Tier 2: You must be playing in the second tier of the Desert map. The graves won’t spawn in Tier 1, so make sure you’ve progressed far enough to access Tier 2 content.
Find and Disturb Four Graves: Locate and interact with (or “disturb”) four random gravestones scattered across the Desert map. Each time you disturb a grave, one of four different ghosts will spawn:
- White Ghost
- Black Ghost
- Purple Ghost
- Red Ghost
Pro Tip: After you find the first grave and defeat the White Ghost, a yellow exclamation mark will appear on your screen showing the location of the next grave. This makes the process much easier than randomly searching the entire map.
Defeat the Ghosts: Eliminate all four spectral enemies that appear. Each ghost has different attack patterns and health pools, so be prepared for varied combat scenarios. The order in which you defeat them doesn’t matter, but you must defeat all four to progress.
Summon and Defeat Calcium’s Dad: After the ghosts are defeated, a skeleton statue will appear somewhere on the map. Interacting with it summons the Undead Boss, known as “Calcium’s Dad.” This boss fight is the final step to permanently unlocking the Graveyard map for all future runs.

Calcium’s Dad Boss Strategy

Calcium’s Dad uses the same attack patterns as the Scorpionussy boss, so if you’re familiar with that fight, you’ll have an advantage here. Here are some key strategies:

Avoid Greed Shrines: Activating Greed Shrines will make this fight significantly harder. Focus on damage and survival shrines instead.
Use Area Damage: Weapons with good area coverage work well against his multiple attack patterns.
Stay Mobile: His attacks are telegraphed but can be devastating if you’re caught standing still.
Prioritize DPS: This isn’t an endurance fight – the faster you can defeat him, the better.

Once you defeat Calcium’s Dad, you’ll receive a notification that the Graveyard map has been permanently unlocked. This unlock applies to all characters, not just Calcium, so you can now access the Graveyard with any character you choose.

Step 2: Unlocking the Scythe Weapon

Now that you have access to the Graveyard map, you’re ready for the next major step: unlocking the Scythe weapon. This is crucial because Roberto’s unlock is directly tied to obtaining this specific weapon. You cannot unlock Roberto without first unlocking the Scythe.

There are two different methods to unlock the Scythe, both taking place in the new Graveyard map. Each method has its own challenges and advantages, so I’ll detail both so you can choose the approach that best suits your playstyle.

Method A: Defeat Big Bob (The Recommended Approach)

This method is generally considered more straightforward because you can prepare for the fight and control when it begins.

Enter the Crypt: Within the Graveyard map, locate and enter the Crypt area. This is typically found in a central or easily accessible location.
Collect Four Crypt Keys: Open chests inside the Crypt to gather four Crypt Keys. The keys drop randomly from chests, so you may need to open several chests to collect all four.
Summon Big Bob: Once you have all four Crypt Keys, use them to summon the boss Big Bob. There’s usually a specific altar or summoning circle in the Crypt where you can use the keys.
Defeat Him: Engage in battle with Big Bob and defeat him to unlock the Scythe weapon.

Big Bob Fight Strategy:

Big Bob has moderate health but hits hard with melee attacks
His attack patterns are relatively predictable compared to Spooky Steve
Focus on dodging his charge attacks and counter-attacking during recovery periods
Weapons with good single-target DPS work well here
Area damage weapons can help if he spawns additional enemies during the fight

Method B: Defeat Spooky Steve (The Challenge Approach)

This method is more challenging but can be faster if you’re already in the Crypt and don’t want to spend time collecting keys.

Fail to Exit the Crypt in Time: Once inside the Crypt, if you do not exit before the timer runs out, you’ll trigger the alternative boss encounter.
Face Spooky Steve: The boss Spooky Steve will automatically appear. This is not a fight you can prepare for in the same way as Big Bob, as it’s triggered by time rather than player choice.
Win an Intense Battle: Spooky Steve has an enormous health pool (approximately 340.3Ud) and represents one of the most challenging boss fights in Megabonk. Defeating him rewards you with the Scythe unlock.

Spooky Steve Fight Strategy: This fight demands a powerful build and specific preparation. Here’s the optimal setup:

Category	Recommended Items	Purpose
Weapons	Dexecutioner	Primary damage dealer
Tomes	XP Tome, Cooldown Tome, Evasion Tome	Leveling speed and survivability
Items	Moldy Cheese, Boss Buster, Big Bonk	Damage amplification

Key Strategy Points:

Maximize Damage: Every upgrade should focus on increasing your damage output
Attack Speed is Crucial: Faster hits mean more DPS against his massive health pool
Cooldown Reduction: Essential for maintaining your abilities throughout the long fight
Survivability: The fight can last several minutes, so you need sustainable defense
Positioning: Stay mobile and avoid getting cornered

Pro Tip for Spooky Steve: This fight can take 5-10 minutes depending on your build. The Dexecutioner as a primary weapon, supported by items like the XP Tome, is highly recommended. The XP Tome will help you level up quickly, allowing you to make your character’s abilities almost constant and gain near invincibility through rapid leveling.

Step 3: Claiming Roberto

Once you have successfully unlocked the Scythe weapon by defeating either Big Bob or Spooky Steve, the character Roberto will automatically be added to your character selection screen. There’s no additional quest or requirement – simply check your character roster, and Roberto will be available for your next run.

The unlock is permanent and account-wide, so you won’t need to repeat this process unless you’re playing on a different account or platform.

Why Roberto is Worth the Effort?

After going through this extensive unlocking process, you might be wondering if Roberto is actually worth all the effort. Based on my testing and community feedback, the answer is a resounding YES.

Roberto is considered a top-tier character in the current Megabonk meta, and his power comes from a game-changing item-based passive ability that can grant you free chests during runs. This passive significantly accelerates your power growth and increases your chances of successful, high-score games.

Roberto’s Passive Ability Explained

Roberto’s passive ability has a chance to spawn additional chests throughout your run. These chests are completely free and don’t require any currency or resources to open. Here’s why this is so powerful:

Economic Advantage: More chests mean more items, weapons, and upgrades without spending silver
Faster Power Scaling: Additional items allow you to reach powerful builds more quickly
Increased Flexibility: More item options mean you can adapt your build to different situations
Higher Score Potential: More items and upgrades directly translate to higher scores
Consistency: The passive reduces reliance on RNG for item drops

In the current Megabonk meta where items are extremely important for success, a character that generates free chests provides an incredible advantage that can make the difference between a failed run and a record-breaking performance.

Advanced Tips and Strategies

Now that you understand the basic unlocking process, let me share some advanced strategies that most guides don’t cover. These tips will help you unlock Roberto more efficiently and prepare you for using him effectively once he’s unlocked.

Preparation Before Starting

Level Up Calcium: Before attempting the Graveyard unlock, make sure Calcium is at least level 10-15. Higher levels mean better stats and more survivability during the ghost fights and boss battle.
Unlock Key Items: Focus on unlocking items that work well with Calcium’s kit. Area damage items and survivability upgrades will make the initial unlock process much smoother.
Practice Desert Tier 2: Spend some time familiarizing yourself with the Desert Tier 2 map layout. Knowing where graves typically spawn will save you valuable time during the unlock process.

Boss Fight Optimization

Build for the Long Haul: Especially for Spooky Steve, build sustainability over burst damage. You’ll be fighting for several minutes, so you need to maintain your effectiveness throughout the entire encounter.
Shrine Selection: Choose shrines that complement your playstyle:
- Damage Shrines: Good for Big Bob fights
- Survivability Shrines: Essential for Spooky Steve
- Speed Shrines: Helpful for both, allowing better positioning
Weapon Synergy: Some weapons work better together than others. Experiment with combinations that offer both single-target damage (for bosses) and area coverage (for adds).

Post-Unlock Roberto Strategies

Once you have Roberto unlocked, here’s how to maximize his effectiveness:

Chest-Focused Builds: Since Roberto generates more chests, build around item synergies and combinations that scale with the number of items you have.
Economic Items: Items that affect chest quality, item rarity, or silver generation work exceptionally well with Roberto’s passive.
Early Game Power: Use your additional early-game chests to snowball your power faster than other characters can.

Common Mistakes to Avoid

Through my research and testing, I’ve identified several common mistakes that players make when trying to unlock Roberto. Avoiding these will save you time and frustration:

1. Skipping Character Preparation

Many players try to unlock the Graveyard with an under-leveled Calcium or without proper items. This makes the ghost fights and boss battle much more difficult than they need to be.

Solution: Spend time leveling Calcium and unlocking key items before attempting the Graveyard unlock.

2. Wrong Map Tier

Players often try to find graves in Desert Tier 1, where they don’t spawn. This leads to wasted time and confusion.

Solution: Always ensure you’re in Desert Tier 2 when attempting to find graves.

3. Poor Boss Build Choices

Going into the Big Bob or Spooky Steve fights with the wrong build can make these encounters nearly impossible.

Solution: Prepare specific builds for each boss, focusing on the right balance of damage, survivability, and utility.

4. Impatience with Spooky Steve

Spooky Steve has a massive health pool, and many players get frustrated and make mistakes during the long fight.

Solution: Accept that the Spooky Steve fight will take time. Focus on consistent damage and survival rather than trying to rush it.

FAQ

Q: Can I unlock Roberto without the Graveyard map?

A: No. Unlocking the Graveyard map by defeating Calcium’s Dad is an absolute requirement. The Graveyard is where you’ll find the Crypt and the bosses needed to unlock the Scythe, which in turn unlocks Roberto.

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, which in turn unlocks Roberto. Big Bob is summoned via keys, while Spooky Steve appears if you take too long in the Crypt. Most players recommend Big Bob as the more manageable option.

Q: Which boss is easier for unlocking the Scythe?

A: Big Bob is generally considered the more straightforward method, as you can prepare for the fight and control when it starts. Spooky Steve has a massive health pool and punishes slower builds, making him a harder but optional challenge.

Q: What is Roberto’s main strength?

A: Roberto’s strength lies in his passive skill, which generates additional free chests during runs. This provides a major economic and item advantage throughout your run, allowing for faster power scaling and more build flexibility.

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, you can use any character to attempt the Scythe unlock.

Q: How long does it take to unlock Roberto?

A: The total time varies based on your skill level and preparation, but typically:

Graveyard unlock: 15-30 minutes
Scythe unlock: 20-45 minutes (depending on which boss you fight)
Total time: 35-75 minutes for most players

Q: Is Roberto worth unlocking in Megabonk?

A: Yes, Roberto is definitely worth unlocking because of his items-focused passive. Even in the new Megabonk meta, Items are extremely important, and a character that gets free chests will make for some exciting gameplay and significantly increase your success rate.

Q: What happens if I fail a boss fight?

A: If you fail to defeat Big Bob or Spooky Steve, you’ll need to try again in a new run. The Crypt Keys you collected will be lost, but your progress toward unlocking the Graveyard map remains.

Q: Can I unlock Roberto in co-op mode?

A: The unlocking process is designed for single-player, and most of the quest mechanics (like disturbing graves) don’t work properly in co-op mode. It’s best to attempt this unlock solo.

Conclusion

Unlocking Roberto in Megabonk’s Spooky Update is a multi-stage challenge that adds significant depth to the game. The journey involves unlocking a new map with Calcium, then venturing into that Graveyard to claim the Scythe by defeating a major boss like Big Bob or Spooky Steve.

While the process requires time, skill, and preparation, the effort is well worth it.

His chest-generating ability provides economic and strategic advantages that can transform your gameplay experience.
