You have waited months to build your ultimate vertical floating city, pre-loaded the files, and cleared your schedule. You click “Play,” and… nothing. Or worse, a cryptic Unity “Fatal Error” pops up. Launch day issues in complex physics simulators are frustrating, but they are rarely unfixable.

Whether you are facing a black screen, random crashes to desktop (CTD) while building your tower, missing DLL files, or unplayable frame rates during a massive ocean storm, this guide covers the most effective solutions to get you back into the game.

Editor’s View: The “Day One” Curse

“I remember trying to launch All Will Fall on release day. It crashed every time the tinyBuild logo appeared, right before rendering the ocean. I almost refunded it.

Before you give up on your colony, realize that 90% of these crashes are caused by three simple things: corrupted texture downloads, missing C++ libraries, or overlay conflicts messing with Unity’s rendering pipeline. I’ve tested the methods below on my own rig (RTX 4070 / Win 11), and Method 2 was the one that finally solved it for me.”

Check First: All Will Fall System Requirements

Before debugging, ensure your PC can actually run the game. Calculating structural integrity and real-time water physics for a massive floating city is incredibly CPU-intensive. Trying to run All Will Fall on below-minimum specs is the most common cause of “silent crashes” (where the game closes directly to your desktop without an error code).

Method 1: Verify Game Files (Steam/Epic)

Corrupted installation files—especially broken ocean shaders or missing audio banks—are the #1 cause of All Will Fall crashing on startup.

For Steam Users:1Right-click All Will Fall in your Library.

2เลือก Properties > Installed Files.

3คลิก “Verify integrity of game files”.

4Wait for the process to finish (it may re-download some missing structural assets).

For Epic Games Users:1Go to your Library, and click the three dots (…) on the game card.

2เลือก Manage > Verify.

Method 2: Update Drivers & Visual C++ Redistributables

All Will Fall runs on the Unity 6 engine, which strictly requires updated software environments to handle complex water rendering and vertical physics calculations.

✦
GPU Drivers: Update your NVIDIA (Game Ready Driver) or AMD (Adrenalin) drivers to the latest version. Outdated drivers will crash the moment the game tries to render ocean reflections.

✦
Visual C++ รวมทุกอย่างไว้ในหนึ่งเดียว: If you get errors like MSVCP140.dll missing หรือ VCRUNTIME140.dll not found, you need to reinstall the Microsoft Visual C++ Redistributables (install both x86 and x64 versions).

✦
DirectX: Ensure DirectX 12 is fully updated via Windows Update.

Method 3: Fix Black Screen & Overlay Issues

If you hear the ambient audio of ocean waves and creaking metal but see a black screen, or the game closes instantly, it is likely a conflict with background apps trying to hook into the game window.

🔥
Disable Overlays: Turn off the Steam Overlay, Discord Overlay, and NVIDIA ShadowPlay/Overlay completely.

🔥

Fullscreen Optimization:

➤Right-click the game’s .exe file in your installation directory > คุณสมบัติ.
➤ไปที่ ความเข้ากันได้ แท็บ.
➤Check “Disable fullscreen optimizations”.
➤Check “Run this program as an administrator”.

Method 4: Common Error Codes & Fixes (DLL / UnityPlayer)

Here are specific solutions for the most common error messages colony leaders are reporting:

Error 0xc0000005 (Access Violation)

Usually caused by strict antivirus software blocking the engine from accessing your RAM. Whitelist the All Will Fall installation folder in Windows Defender or run the game as Administrator.

“Out of Video Memory” Error

Your GPU VRAM is full. This is common on Intel 13th/14th Gen CPUs when Unity compiles shaders. Try lowering “Ocean Quality” and “Texture Resolution” to Medium before launching, or underclock your CPU slightly using Intel XTU.

UnityPlayer.dll Crash / DX12 Error

Right-click the game in Steam > Properties > Launch Options. Type -force-d3d11 to force the Unity engine into DirectX 11 mode. It disables some advanced water effects but massively improves stability on older hardware.

EXCEPTION_ACCESS_VIOLATION

This is often a RAM instability issue caused by the heavy garbage collection Unity performs when your city grows past 500 building pieces. Disable XMP profiles in your BIOS temporarily or close high-memory background apps like Chrome.

Method 5: Fix Low FPS & Stuttering

Is All Will Fall running like a slideshow when your tower gets too high?

✨
Lower Water Physics / Volumetrics: These settings consume the most CPU and GPU power in colony sims.

✨
Enable DLSS/FSR: Turn on Upscaling in the specific graphics settings to maintain high frame rates while zoomed out.

✨
Set High Priority: Open Task Manager > Details > Right-click AllWillFall.exe > Set Priority > High.

The Workaround: Skip Laggy Events with XMODhub

Sometimes, All Will Fall crashes not because of your PC hardware, but because of unoptimized code during massive dynamic weather events (like tidal waves or hurricanes) that overload the physics engine.

XMODhub offers unique tools to help bypass these technical hurdles:

🚀
Speedhack: Use the trainer to slow down the game (0.5x speed) during high-load storm sequences. This gives your CPU more time to calculate structural physics and prevents fatal spikes and crashes. Alternatively, speed it up to skip boring, laggy resource-gathering phases.

🚀
Save Manager: Automatically backup your save before placing a risky, heavy structure on the edge of your city, so you never lose progress due to a random physics collapse and subsequent game crash.

How to Get Started with XMODhub

Getting the ultimate toolkit for All Will Fall is simple. Just follow these steps:

1
Download & Install: Get the latest version of the XMODhub Client from our Official Site.

2
Auto-Detect: Launch the app. It will automatically scan your PC and locate All Will Fall in seconds.

3

คำถามที่พบบ่อย

Q: Does All Will Fall support Windows 10?

A: Yes, but ensure you are on version 22H2 or newer. Older Windows 10 builds lack the necessary DirectX Agility SDK updates required by modern Unity games.

Q: Will reinstalling fix the crash?

A: Reinstalling should be your absolute last resort. Try Verifying Integrity (Method 1) first, as it does the exact same thing but repairs only the broken files much faster.

Q: Is there an optimization patch coming?

A: The developers at All Parts Connected have acknowledged the late-game lag and multithreading physics issues. Check the XMODhub news section for updates on upcoming performance patches.

สรุป

Launch issues are painful, but they are temporary. By verifying your files, updating your C++ libraries, forcing DX11 mode, and optimizing your drivers, you should be able to fix the All Will Fall crash on startup error and get back to managing your floating settlement.

If the game is still suffering from poor optimization or physics calculation bugs when your city gets massive, XMODhub can help bridge the gap. Use Game Speed adjustments to bypass sluggish storm events and Auto-Backups to secure your progress until the official patch arrives.
