An achievement built around a person, not a task
Most game achievements mark something a player can deliberately do: finish a level, make a difficult shot, or explore a hidden corner. Garry’s Mod has one with a different kind of requirement. It unlocks when you join a multiplayer server where Garry Newman, the game’s creator, is playing.
That makes the achievement depend on a meeting rather than a test of skill. You can learn the condition, but you cannot complete it simply by repeating a set of actions. Newman has to be in a server, and you have to enter that same game while he is there.
Chance becomes part of completion
A server is a shared online game session, so the achievement ties a private checklist to a moment involving another player. For completionists—players who aim to earn every achievement—the challenge is not mastering a particular mechanic. It is being in the right place at the right time.
The design turns the creator’s presence into a piece of the game’s social world. A routine act of joining a server can become the final step in a collection, but only if the person at the center of the condition happens to be playing there. That makes the unlock less like a trophy for what you did and more like a record of whom you happened to meet.
