Garry's Mod is a physics sandbox. There are no specific goals in comparison with other video games. The creator gives you the tools and leaves you. It's possible to think up new objects and connect them. It depends only on you whether it's a car, a house, or something that doesn't have got name yet.
Graphics and Sound
The game was released in 2006, so it's impossible to say that the graphics there is innovative. Anyway, then it was perfect, and even today it doesn't irritate eyes. If you want to improve quality of the whole picture, you can download special modes from Steam.
If we talk about sound, it's far from ideal. Many voices and various noises can't be called realistic. It's also possible to find a way out, installing modifications that have been created in Steam workshop.
At the very beginning, in the hands of the character appears a physics gun. This is a special type of tool, using which you can edit objects, move them, and perform any other actions. Pressing on the Q button, you'll open an inventory and will have the ability to generate items. To change the buttons, you need to go to the settings in the main menu.
There are no tasks, completing which, you will finish the game. You just have to create anything you can imagine. What is more interesting: you can open the menu which contains a huge number of opportunities to create NPCs, weapons, heroes, and much more. You can customize different weather conditions, as well as the behavior of the characters on the map. This is a whole workshop, and here you are the master.
Garry’s Mod even allows you to insert YouTube videos into game items to give instructions on how to go through certain sections. It all depends on your imagination and how you decide to show it.
As the game has been developing, new game modes were appearing, such as Dog Fight Arcade (battle in the air), PropHunt, Ascension, and others. You can download all of them in addition to the game.
E.g., in the Prop Hunt regime there are two teams of hunters and props. Props are objects, you can become one of them and hide somewhere. And the hunters must find you and destroy. This mode is very similar to hide-and-seek.
Of course, Garry's mod is an exciting project in which you can create and customize various things and personages, including popular characters from the games. You can also spend time in incredible regimes with other players.
Anyway, it can't last long. After several days or weeks, you'll understand that you don't want to do anything there. Probably, it may be caused by the absence of a big goal.
So, Garry’s Mod is a large sandbox where you will have complete freedom of action. Do whatever you want and wherever you desire. Under your influence there's a huge world: create, destroy, and customize!
