Payday2 BLT requires the following dependencies, which are all statically linked.

  • OpenSSL
  • cURL
  • zlib
  • Detours


OpenSSL should be compiled as static libraries and the libraries placed in the lib directory, and the headers in the incl directory


cURL should be compiled as static, with the WITH_SSL parameter set to 'static' and the previously compiled OpenSSL libraries in the dependencies directory.


zLib should be compiled as static. I had to add SAFESEH handling to the MASM objects in order for this to be compatible with Payday2-BLT


A compiled version of detours is included, and all terms of the included Microsoft Research Shared Source License Agreement (detours_license.rtf) are applicable.


All documentation can be found via the navigation bar the Payday Mods site, or just go to it directly. It's also available on GitHub (or click the 'Edit on GitHub' button) so that you can contribute stuff if you need to, or need us to fix something.
The documentation is written in markdown with the help of MkDocs and ReadTheDocs.


The Payday 2 BLT was made by James Wilkinson and SirWaddlesworth. We're friendly guys sometimes, so if you need help or want to discuss something you can reach us at any of the contact details we've got listed over here.
We've also had help from a bunch of other people who've tested stuff, reported bugs, suggested changes, and everthing else. So thanks to GREAT BIG BUSHY BEARD, Kail, Dougley, and everybody else!
