SuperBLT is a fork of the BLT mod-loading hook for PAYDAY 2, with a number of major improvements, such as a cross-platform audio API and the ability to alter any base-game XML file without the hassle of modifying bundle files (greatly alleviating the need for Bundle Modder).


  • Download and install the Microsoft Visual C++ 2017 Redistributable package (x86) (you will only need to do this once, even if you later reinstall SuperBLT)
  • Download the Latest Release DLL, and place it in your PAYDAY 2 folder (alongside payday2_win32_release.exe).
  • Start the game, and SuperBLT will prompt you to download the basemod. Select Yes, and it will notify you when it's done downloading. At this point, SuperBLT has been fully installed.

However, if you've previously used vanilla BLT, you will have to:

  • Delete IPHLPAPI.dll - This is the original BLT DLL, and you can't have both installed at the same time due to conflicts.
  • Delete mods/base - This is another part of the original BLT, and SuperBLT will download its own version. However, you must first delete the old version.

Regarding the IPHLPAPI.dll vs. WSOCK32.dll situation

Some computers, for reasons that are not apparent, refuse to load the IPHLPAPI.dll file as used by vanilla BLT. This seems to primarily affect Windows 10 systems. For this reason, SuperBLT has switched over to hooking WSOCK32.dll instead, which I've yet to see any trouble from.

If, for whatever reason, you require an IPHLPAPI.dll version, you can download the IPHLPAPI Release DLL, and install it like you would with the normal (i.e. WSOCK32.dll) version. Just don't install both at the same time.

Development version

If you want to try the most recent version of the DLL for some reason you can get it from AppVeyor. These versions contain the most recent changes that haven't been published officially yet and may have new features or minor bugfixes. Just note that the ingame download manager will claim there is a new version for the DLL if you use anything other than the release version of it.
