⚡ TL;DR - What You Need to Know

📋 Overview

Version 1.0.12 represents a major stability and balance update for Megabonk, addressing critical issues that emerged during the game's explosive first month. Following leaderboard exploits that disrupted the competitive community and meta strategies that resulted in multi-hour endgame sessions, developer vedinad implemented comprehensive fixes alongside targeted weapon adjustments.

This patch focuses on three core areas: securing leaderboard integrity through anti-cheat measures and permanent ban systems, redesigning the Final Swarm phase to create faster and more challenging endgame experiences, and rebalancing progression systems to encourage build diversity rather than single-strategy dominance.

⚔️ Weapons Affected by This Patch

⚖️ Balance Changes at a Glance

🔼 Buffed

Chaos Tome – Reward bonus increased by 50%, making the high-risk gamble more worthwhile for experimental builds.
Black Hole – Default projectile size increased by 20%, improving base crowd control without item investment.
Bush (Marksman Passive) – Cooldown now scales faster (-0.4s every 10 levels), reaching maximum efficiency (1s cooldown) at level 100.
Duration-Based WeaponsDexecutioner, Axe, and Sword now function properly at high duration values thanks to projectile cap fixes.

🔽 Nerfed

XP Tome – Experience gain reduced from 9% per level to 7%, slowing overall progression speed. (Developer indicated willingness to revert based on community feedback)
Black Hole – Proc coefficient reduced from 0.9 to 0.7, bringing it in line with similar weapons (Sword, Axe, Aura) and reducing synergy with on-hit effects like Moldy Cheese.
Joe's Dagger – Damage scaling capped at 200% per minute per dagger. With 10 daggers, maximum scaling is 2000% per minute, preventing extreme late-game dominance while preserving early/mid-game strength.
Rolly Bones Enemies – Movement speed reduced in Desert biome to decrease late-game farming efficiency.

📚 Tomes & Items Affected

👻 Final Swarm Rework

The endgame phase received a complete overhaul to address the problematic meta that encouraged players to endure hours-long sessions at sub-2 FPS framerates. The previous Final Swarm could be indefinitely sustained through execution chains and Black Hole stalling, creating an unhealthy competitive environment where leaderboard positions were determined by endurance rather than skill.

Developer Commentary: "The current meta required you to wear sunglasses and watch a slideshow at 1.5fps for 5 hours to get a WR. This was never intended, and I don't think anyone actually enjoyed that."

Key Changes

Meta Impact: The update shifts competitive strategy from "infinite sustain + stall" to "burst damage + efficient routing." Builds focused on raw DPS and mobility are now favored over pure survivability compositions. Check out our updated build guides for post-patch strategies.

🎭 Characters Affected by This Patch

Bush received significant buffs to his Marksman passive, Spaceman got bug fixes for his XP passive, and Megachad's Theme was reportedly added to the game soundtrack. View the full character roster and their updated best builds.

🏆 Leaderboard Improvements & Anti-Cheat

Following several days of leaderboard instability caused by exploits, comprehensive security measures have been implemented to protect competitive integrity.

Security Enhancements

Backend Secured – Multiple exploits that allowed leaderboard manipulation have been patched
Permanent Ban System – Confirmed cheaters are added to a global ban list and permanently removed from all leaderboard displays
"All Leaderboards" Temporarily Removed – The combined leaderboard view has been disabled pending implementation of character-specific filtering and additional anti-cheat measures
⚠️ Warning to Cheaters: According to the developer: "Cheaters you better watch your ass or im clapping your cheeks back to the shadow realm where you belong."

🔧 Stability & Critical Bug Fixes

Major Fixes

Save File Corruption Fixed – Resolved the critical issue where crashes or forced exits (Alt+F4) could corrupt save data, preventing progress loss
Black Hole Hitbox Corrected – Fixed bug where Black Hole hitboxes were approximately 10x larger than the visual projectile, essentially covering entire maps
Spaceman Passive Restored – Spaceman's passive ability now correctly grants XP bonus per level as intended
Spiky Shield Stacking – Corrected stacking behavior for Spiky Shield item
Weapon Duration Logic Improved – Fixed projectile cap system preventing weapons like Dexecutioner, Axe, and Sword from firing at high duration values. Previously, duration would keep projectiles "active" longer than intended, filling the cap with invisible/inactive projectiles

Performance Optimizations

⚔️ Detailed Weapon Analysis

Black Hole

Role Change: Crowd Control → Crowd Control (Reduced Synergy)

Joe's Dagger

Scaling Cap Introduced: 200% damage increase per minute per dagger

Chaos Tome

Risk/Reward Rebalanced: 50% increase to all stat bonuses

XP Tome

Progression Speed Reduced: 9% → 7% XP gain per level

Bush (Marksman Passive)

Scaling Improved: Cooldown reduction now provides clear milestones

💡 Strategic Implications

Build Diversity Opens Up

With Joe's Dagger capped and Final Swarm reworked, the competitive meta now rewards flexibility over single-strategy optimization. Previously dominant "stall until infinite scaling" approaches are no longer viable.

New Competitive Meta

Quality of Life Wins

🎯 Pro Tip: Experiment with previously underused weapons now that duration scaling works correctly. The Dexecutioner + Duration Tome combination, previously broken, is now a legitimate build path. See our Beginners Guide page for more strategies.
