ReHLDS 3.15.0.896

Reverse-engineered (and bugfixed) HLDS

What is this?

ReHLDS Enhanced version of the HLDS engine with bug fixes, security patches, and optimizations for stable servers.

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

HLDS is fully compatible with the official pre-anniversary edition of HLDS (engine version <= 8684) downloaded by steamcmd. All you have to do is to download ReHLDS binaries and replace original swds.dll/engine_i486.so
