What you can customize

Swap or remove assets safely. Everything here is non-cheat and aligned with StyLiS/other game moderation guidelines.

Gun sounds

Replace firing, reload, and foley sounds with your own set.

Hit & kill

Personalize hitmarker and kill confirmation sounds.

UI cues

Subtle UI audio for menus and confirmations.

Skins

Swap weapon skins. Preview instantly.

Textures

Smooth out textures or remove them for performance.

Sleeves

Toggle sleeves; tint follows team colors by design.

Default skyboxes

Auto-enable default skyboxes for played maps.

Custom skyboxes

Best with Bloxstrap — drop files into the folder and go.

Night maps

Note: Custom skyboxes won’t apply to night-time maps.

Can’t run run.bat?

Do this in order. It’s quick, and handles the common causes.

  1. Check your folders. storage must sit next to run.bat in the same directory.
  2. Look for autoupdate.py in storage. If it’s missing, Fleasion will open a link to download it. Put the file into storage.
  3. Run it. Try launching run.bat again.
  4. If it still fails:
    • Uninstall Python, then reinstall the latest from python.org/downloads.
    • During install, ✔ Add to PATH.
    • After reinstall, run run.bat again ^_^
🤓 Nerd yap (why the error appears)
The error shows up whenever:
  • There’s no autoupdate.py in the storage folder
  • The Fleasion code encounters an error (usually because Python is outdated)
  • You can’t call python from terminal (Python not on PATH)

Changes keep disappearing?

On Windows, go to Storage Sense and turn it off. Then re‑apply your Fleasion changes. Storage Sense cleans temporary files — Fleasion edits temporary cache to achieve your results, so they were getting wiped.

Frequently asked questions

Quick answers — built‑in options are allowed by StyLiS developers.

Hiding my arms seems like an advantage. Is this cheating?
No. Fleasion isn’t a cheat and every built‑in customization option is allowed by StyLiS developers.
Is Fleasion a virus?
No. Fleasion is open‑source. No adware or malware.
How do I get custom skyboxes?
We support them with Bloxstrap. Use this shortcut to open the folder:
cmd /c "mkdir "%userprofile%\AppData\Local\Bloxstrap\Modifications\PlatformContent\pc\textures\sky" & explorer "%userprofile%\AppData\Local\Bloxstrap\Modifications\PlatformContent\pc\textures\sky""
My custom skyboxes aren’t working!
On night maps, custom skyboxes don’t work. Use “default skyboxes” after playing a bit to activate on maps you already played.
It says it didn’t find the hash — what now?
Some actions need cache to load. Try: equip the sight; trigger the sound; equip/preview the skin; play maps to load default skyboxes & textures. You may also need to rejoin the Texture Game.
Why are sleeves sometimes red/blue?
Phantom Forces tints sleeves by team color. Not removable.
Can we add something that doesn’t exist in the game yet?
No. Fleasion can only replace or remove, not create.
Can I request a hash / asset?
Yes — request it in our Discord. Some assets might not be possible.
