Viral Achievement
CONCEPT
An achievement/trophy that a player can only get by interacting with another player online who has already earned the same achievement/trophy.


Concept

Often these achievements are awarded first to a player who has played with, killed, or been killed by a developer of the game. Then, any other player who performs that same action to the player with the achievement will also earn the achievement. Due to the nature of these achievements, they are often hard to come by when the game first comes out, but become easier to come by the more people play. Eventually, it gets to the point where almost everyone has it, and it becomes nearly impossible to not earn the achievement.
