There are no set rules or objectives to meet but the ones you make yourself, which leads to some of the most creative scenarios one can find. The game provides free-rein over everything you can see, something that's unusual, since most sandbox and open-world games don't go that far. At its core, this is a game where the ability to mess around with objects is the primary feature, not a secondary mode. Though it does feature actual game modes like the popular 'Trouble in Terrorist Town,' what Garry's Mod is truly known for is its sandbox mode.
Valve's Garry's Mod on Steam takes the concept and turns it into one of the most unusual games imaginable. We've seen this concept before, such as in Grand Theft Auto V's 'Director Mode,' which allowed the use of various characters or NPCs to roam around and do as the player wished. They're open-world experiences that give players the freedom to explore or do anything in the game's limits as you please.
