Those are recompiled Damage Metamod Plugin for HLDS to modify the damages, devised by Pierre-Marie Baty from RACC. No major changes apart from being compiled for SteamPipe by including HLSDK 2013 and Metamod v1.21-p source codes. Let me know if those bots fail for HLDS SteamPipe servers!
>> Dropped '_i386' suffix for Linux Build
>> Added support for SteamPipe HLDM, Op4, DMC
>> Linux binary optimised for i686 and using GCC 4.8
>> Both builds recompiled using a newer compiler
Note: This DLL package is not fully tested on all servers, please report to me.
