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.

New weapons

SMOD adds over 20 weapons to the single player game, as well as custom weapon scripts that can import weapons from other Source engine games such as Counter-Strike, or create new ones from scratch. Most weapons now allow you to look down the sights when a key is pressed while holding them. This can affect other aspects of the game, such as movement speed and accuracy.

Bullet time

Bullet time slows the game environment and makes physics, enemy reactions, and even bullets move at an extremely slow pace. It also produces visual effects that are similar to the ones in F.E.A.R. As with the flashlight and sprinting, the player's auxiliary battery is drained by bullet time, but at a much faster rate.

Gordon's kick

A melee attack possibly inspired by a similar move in the game Duke Nukem 3D. The move is fully integrated into the physics engine so if you kick an object, it can be sent flying. The strength of the kick varies depending on the inertia of the player and the kick_powerscale setting. A quirk of the attack is the ability to create a dark energy orb (like those fired from the AR2) after approximately 10 rapid kicks, after which the orb can be kicked toward hostiles.

New NPCs

These includes the attack drone, rebel Combine troops, houndeyes, fully working stalkers, optically camouflaged troops, and 'super soldiers' with antlion-like jumping capabilities. Combine soldiers can be set to use energy-based riot shields which block bullets and add to game difficulty. They may also randomly appear with specially colored uniforms that allow them to take a huge amount of damage. Human NPCs can use most of the new weapons the mod adds to the game.

Enhanced visual effects

SMOD adds many new tweaks and improvements to the graphics of the Source engine. A few examples of the new effects that can be seen are: motion blur, dynamic muzzle fire lighting, depth of field effects for weapons, and greatly improved particle effects.

New functionality

Many weapons and objects can be used in new ways with SMOD. For example, the crowbar can be thrown at enemies with secondary fire, and similar to Garry's Mod, props in a level can be replicated and manipulated, then used for various purposes.

New events and plot content

Examples include the skippable episode "Where's my Boat?", and the infamous "Pick up the can" officer burning to death because the can has been replaced with a gas tank.


The mod adds several visceral features, such as new blood decals, twitching bodies, spurting blood from fatal wounds that splashes onto nearby objects, and gibbing (with edible gibs that increase health). These options can be switched off to reduce the gore level for a more sensitive audience.


Every aspect of the mod is easy to modify with console commands and CFG files. This makes it simple for modders to use SMOD as a base for their own mods. The SMOD40 readme file includes the following text, so you can freely develop and publish a new SMOD based mod:

"To other MOD authors.

I permit to making your MOD with the SMOD (binary) files.

You don't need to write "Author" or "ìŽÒ" in your MOD credits. You don't need to include "SMOD" in your MOD name.

I don't have obligation(duty?) to maintain your MOD. Therefore I don't maintain SMOD for your MOD. But it is done sometimes at my whim.

Because I want to do it."

Addon files

These allow almost any Source map to be made into a single player level by placing NPCs, items and props at predetermined or random places throughout the map, setting conditions for victory, and so on.

We, Dev.Muffin hereby present you the latest "unofficial" update to SMOD40aq that hopefully become the future of SMOD.

SMOD Standalone is a "updated" version of SMOD client that takes advantages of some Orangebox engine features like LAA flag; it also fixes LUA and introduces a new file structure allowing for smaller 3-rd party SMOD mods.

If you're into SMOD we recommend you to try it out, because this "update" is not made mainly for SMOD devs, but also users that love SMOD but are unable to play it due to Steam and Half-Life 2 updates.

This is one of the best ways to replay Half-Life 2 if you get bored of the old weapons and game mechanics.
