Garry's Mod

Garry's Mod, also known as GMod, is a...well, mod of Half-Life 2. You get to mess around with an almost infinite amount of objects in an almost infinite amount of maps. The possibilities are literally endless. There's also a couple game modes, including but not limited to: -Hide and Seek; exactly what it sounds like. -Prop Hunt; A couple players try to blend in with the map by becoming various objects while the others try to find and kill them. -Guess Who: Prop Hunt, but with player models and special abilities. -Trouble in Terrorist Town (TTT): The OG Among Us with guns. Deathrun: One player is "Death." The other players have to dodge various traps triggered by "Death," and try to make it to the end of the map.
