It is a game that binds all the best aspects of sandbox gaming to one place, and it's completely customizable. Garry’s Mod liberates players with an unprecedented level of control since its release. It still has a big community that engages itself in further developing the game.

Often referred to as GMod, Garry’s Mod is a standalone video game available on Steam. This game enables players to manipulate objects, or props in the game to make creative devices for better gaming.

The players are provided with a Physics Gun and a Tool Gun to manipulate the props and position them wherever they want. Players can also opt to choose multiplayer gaming and communicate with each other via text or voice chat.

Garry’s Mod gives players a sheer amount of freedom. Sure, the game is embedded with maps and characters, but the Steam Workshop takes this game straight to a new level.

A lot of assets from multiple sources allows players to freely reign over the physics, NPCs, vehicles, weapons, objects, and enemies. Players can plan upon the maps from other games, like Left 4 Dead, Portal, and Half-Life 2, and spawn elements from those games as well.



The game comes with two different modes:

  • Sandbox
  • Trouble in Terrorist Town


Sandbox is pretty straight forward. It has maps so that you can mess around with the world. Allows you to spawn NPCs from Half-Life 2, along with ragdolls and props of your choice. Initially, you will be served with two powerful guns, the Physics Gun and the Tool Gun.

With the Physics Gun, you can manipulate any physical object for turning, throwing, drowning, and even naming it. Moreover, the Tool Gun enables us to weld objects together, inflate ragdolls, and many other things that are extremely useful and can’t be described in a paragraph.


On the other hand, Trouble in the Terrorist town has simple and basic rules. You’ll enter the game with a bunch of other players and a couple of them are traitors. The goal of the traitors is to eliminate the other players, and the goal of other players is to eliminate the traitors.

The usable weapons are scattered all over the map, which can be picked by the players. The game doesn’t tell who the traitor is to make it more fun to play.

The game also allows players to play online. You can opt from a lot of different hosts in different modes through which you can play with other players. However, if you’re playing online you might meet players with powerful mods which can be a big disadvantage.
