Megabonk, a chaotic multiplayer party game, has gained attention for its slapstick physics and fast-paced action. However, a critical issue has emerged for many players: an input glitch that causes uncontrollable UI scrolling and infinite forward movement. This bug renders the game nearly unplayable, affecting both keyboard and controller users. In this article, we’ll explore the problem in depth—its symptoms, triggers, community feedback, and potential solutions—across ten structured sections arranged by timeline and relevance.

1. Identifying the Input Glitch The issue begins immediately upon launching Megabonk. Players report that the UI scrolls upward uncontrollably, making menu navigation impossible. In-game, characters move forward endlessly, ignoring player input.

This glitch affects both keyboard and controller setups. Even unplugging peripherals doesn’t resolve the problem, suggesting a deeper software or engine-level conflict.

Symptoms Checklist:

  • UI scrolls upward without input
  • Character moves forward infinitely
  • Input devices appear unresponsive

2. Early Community Reports and Frustration The first wave of complaints surfaced on Steam forums, where users described the game as “completely unplayable.” Despite restarting the game and PC, the issue persisted. Some suspected faulty peripherals, but tests ruled that out.

Players expressed frustration at the lack of official response and the inability to find fixes online. The bug’s severity halted gameplay entirely, leading to refund requests and negative reviews.

Community Feedback:

  • “Game is completely unplayable”
  • “Tried everything—still broken”
  • “No fix available online”

3. Testing Peripheral Conflicts Many players attempted to isolate the issue by unplugging controllers, keyboards, and mice. Some even removed batteries from wireless devices. These steps failed to resolve the glitch, indicating that the problem isn’t hardware-related.

The game may be misinterpreting phantom inputs or stuck signals from inactive devices. However, even with all peripherals disconnected, the bug persists, pointing to a software-level fault.

Troubleshooting Attempts:

  • Unplugging all input devices
  • Testing with fresh installs
  • Disabling Steam Input

4. Reinstalling and Verifying Game Files Reinstalling Megabonk and verifying game files via Steam were common suggestions. Unfortunately, these steps did not fix the issue. Players confirmed that even clean installs reproduced the same input glitch.

This rules out corrupted files or installation errors. The problem likely lies in the game’s input handling code or Unity engine configuration.

File Management Tips:

  • Verify integrity via Steam
  • Try clean install with no mods
  • Clear local cache and config files

5. Investigating Engine-Level Causes Megabonk is built on Unity, which has known quirks with input handling. If the game’s input manager is misconfigured, it can register phantom inputs or fail to reset axis values between sessions.

Developers may have overlooked default input bindings or failed to implement proper deadzone detection. This could explain the infinite movement and UI scrolling.

Engine Insights:

  • Unity input axis misconfiguration
  • Missing deadzone calibration
  • Persistent input state across sessions

6. Controller Mapping and Steam Input Conflicts Steam Input can override game settings, causing unexpected behavior. Players using Xbox or PlayStation controllers reported worse symptoms, especially when Steam Input was enabled.

Disabling Steam Input per-game and resetting controller bindings helped some users temporarily. However, this workaround is inconsistent and doesn’t fix the core issue.

Controller Tips:

  • Disable Steam Input in game settings
  • Reset controller bindings
  • Avoid using multiple input devices simultaneously

7. UI Behavior and Menu Lockout The glitch affects not just gameplay but also the UI. Menus scroll rapidly, preventing players from selecting options or starting matches. This lockout makes it impossible to adjust settings or remap controls.

Some users managed to click buttons by timing their input during scroll pauses, but this is unreliable. The UI behavior suggests that the game is receiving constant “up” input from an undefined source.

UI Symptoms:

  • Menu scrolls upward continuously
  • Buttons become inaccessible
  • Settings menu cannot be navigated

8. Developer Silence and Lack of Patch Notes As of October 2025, no official patch has addressed the input glitch. The Steam support page offers generic troubleshooting steps but no targeted fix. Players have submitted bug reports, but responses are minimal.

This silence has fueled community frustration. Without transparency or updates, players feel abandoned. A hotfix or even acknowledgment would go a long way in restoring trust.

Developer Status:

  • No official fix released
  • Steam support offers generic advice
  • Community requests remain unanswered

9. Temporary Workarounds and Hacks Some players experimented with third-party input managers like DS4Windows or Joy2Key to override default mappings. Others launched the game in windowed mode or adjusted resolution settings to reduce UI lag.

While these hacks occasionally reduce symptoms, they don’t eliminate the glitch. The most consistent workaround is to unplug all devices and use keyboard-only input, though even this fails for some.

Workaround List:

  • Use third-party input remappers
  • Launch in windowed mode
  • Unplug all peripherals before launch

10. Long-Term Solutions and Recommendations To resolve the issue permanently, developers must audit the input handling system. This includes resetting axis values on launch, implementing deadzone detection, and isolating controller conflicts.

Players should continue submitting bug reports and documenting symptoms. If the issue persists, consider requesting a refund or waiting for future patches. Megabonk has potential—but only if its core systems are stable.

Recommendations:

  • Developers: audit Unity input manager
  • Players: document and report bugs
  • Avoid multiplayer until issue is resolved

Conclusion Megabonk’s input glitch is a severe and persistent issue that renders the game unplayable for many users. Despite community efforts to troubleshoot and isolate the problem, no official fix has been released. The bug likely stems from Unity’s input configuration and controller mapping conflicts. Until developers address the root cause, players must rely on temporary workarounds or avoid the game entirely.
