By Onemanshow. NOTE: Only use the patches with the mod it was made for (like installing the SMOD Redux patch into your SMOD: Tactical install). Otherwise you can end up with bugs/problems. To install a patch, extract the archive into the respective mod's folder and MAKE SURE YOU RESTART STEAM BEFORE PLAYING!. Otherwise it will not apply the changes!. DO NOT install these patches into your half-life 2 folder. Only your SMOD, Tactical or Redux folder. As a side note, these patches make SMOD run on the Source SDK Base engine. Make sure you have it installed before playing.
