SMOD is a single player mod of Valve's first-person shooter Half-Life 2. The new content consists of many new NPCs and weapons, new gamemodes, comprehensive customization and tweaking options, new abilities for the player, and new features to the gameplay, such as level randomization and simple branching in the otherwise linear flow of the main episodes.
The main purpose of this mod is to recreate the original SMOD: Tactical Delta 5.56 on the latest Source SDK Base 2013 Singleplayer branch C++ source code. This mod was compiled using Source SDK Base 2013 Singleplayer branch C++ source code. Which means that you will need to have Half-Life 2 and Source SDK Base 2013 Singleplayer to be installed in Steam to play this mod.
