Apple has launched multiplayer gaming service Game Center as part of its 4.1 iOS update.
The social gaming network offers features including achievements, leaderboards, online multiplayer and auto matchmaking. It doesn’t currently work with original iPhones, the 3G or first generation iPod Touches, but supports all newer models. It's also expected to launch for iPad in November.
"Game Centre is all about multiplayer games," Apple CEO Steve Jobs said last week. "It allows you to challenge your friends to games, and they can challenge you. If you don't have any friends it will automatically match you. It will allow you to compare scores, and discover new games."
Touch Arcade forum users have put together a list of games which developers have promised will support Game Center features.
