Trophies
See List of PlayStation 3 games and List of downloadable PlayStation 3 games for a list of titles that support PlayStation 3 Trophies and Achievement (video gaming) for a general description of the concept of achievements/trophies in computer and video gaming.
"Trophies" are an accomplishment tracking system, introduced in the PlayStation 3 system software 2.40 update in July 2008.[29]
The four different types of trophies; bronze, silver, gold and platinum are awarded to players for making specific accomplishments (e.g. Completing a level or defeating a certain number of enemies) or reaching certain milestones in games (e.g. reaching a "pro" rank online). Developers can also choose to make certain trophies hidden so that the trophy's value, title and description is not shown until the user has unlocked it. A gold, silver or bronze trophy is normally awarded based on the difficulty of the accomplishment with each trophy contributing to a 'level' system[30] linked to a player's PlayStation Network profile, with gold trophies contributing more experience level advancement than silver, and silver contributing more experience than bronze. A platinum trophy is automatically awarded to the player once they unlock all other trophies in a game, excluding extra trophies that can only be obtained through downloadable content, and contribute more experience than a gold trophy. However, smaller games such as certain PlayStation Network titles, lack a platinum trophy.[30] Trophies are displayed on a player's PlayStation Network profile screen, which also shows their level.
On November 20, 2008, Sony announced that trophy support would be mandatory for all games submitted to Sony for certification from the beginning of January 2009.[31]
