# [ReHLDS](https://github.com/ReHLDS/ReHLDS) Changelog

**ReHLDS** is a result of reverse engineering of original `HLDS` (build `6152`/`6153`) using `DWARF` debug info embedded into linux version of `HLDS`, `engine_i486.so`.

Along with reverse engineering, a lot of defects and (potential) bugs were found and fixed.
