gMod 9.0.4 is the last version of Garry's Mod to be available for free download, and will not be updated in the future. The NPCs here are called "sitizenami" or city dwellers, and have the same design with a rounded head. gMod 10 (aka Garry's Mod) is available for purchase through Steam, and is the only version being updated.
In addition, the possibility of free online play allows you to adjust the appearance of the protagonist according to the preferences of gamers - picking up clothes and accessories. Network play gives players the same rights, and each player can create, deform and destroy objects, as well as test weapons on them. The same goes for character models - any damage is detailed on the bodies, distorting them according to which projectiles were fired. For example, the recoil from gunshots is now more apparent, and objects deform or fly off when hit by bullets. Due to the fact that it uses a newer engine, the usual actions look much more realistic and believable. This can be office buildings, open spaces, rooms of residential buildings and other places. User can choose a location from the list available from Valve's games, and make any manipulations with objects and characters there.
S Gameplay&Box (Garry's Mod) corresponds to the original Garry's Mod and completely repeats its concepts. This is important, because in the sandbox mode interaction online involves a large number of processes. In addition, the game operates on a new engine, which in turn allows you to avoid some of the bugs that may have occurred in the previous version. Here, all the usual mechanics and opportunities to interact with the surrounding objects have been expanded, making it possible to implement new ideas. S and Box (Garry's Mod) is a semantic extension of the popular project, where in addition to single sessions you can play online with a friend on the pirate.
