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.
Good
A mod that brings out good old memories and nostalgia, and also a good way to replay Half-Life 2 if you're bored of playing the same game all over of the same way. Unfortunately the mod is broken as hell and needs urgent patching because some maps are unplayable because they bring CTDs on loading screens.
