  • Selective Download: Choose to skip 4K videos, language packs, or optional audio.
  • Low-RAM Mode: For users with 2GB or 4GB of RAM, their installers use a unique chunk-based extraction that prevents the system from crashing during decompression.
  • Verify Before Install: A built-in hash checker that ensures your downloaded repack isn’t corrupted before you waste 45 minutes installing it.
  • Sleep Mode Integration: The installer can pause decompression when the computer enters sleep and seamlessly resume.

The centerpiece of Razor12911's work is XTool (often found as xtool.exe), a successor to previous tools like ZTool. XTool is a specialized program designed for pre-compressing game data before it is further compressed by standard archivers like 7-Zip or FreeArc.

Razor12911 has maintained a strong presence on technical forums like FileForums and GitHub, where they provide updates and documentation for other developers.
