Steve Jobs just showed off some screenshots and functionality for Game Center, which will be officially releasing with iOS 4.1 next week. The official app will provide social networking features for App Store games, including friends lists, achievements, "auto matching" (the rest of the world calls that matchmaking), challenges and a host of other cross-platform features for gamers on Apple's mobile platform.
Jobs also invited a few gentlemen from Epic Games onstage to show off "Project Sword," a gorgeous title running in the Unreal Engine inside iOS. It's an action RPG title that's coming soon with full Game Center integration, and the demo featured practically instant multiplayer fighting from a third-person perspective, as well as first-person world exploration. Seriously, this thing looked great, but you don't have to take my word for it -- Epic has already uploaded the very same environment shown in the demo as a free app, so go download and check it out now. It does require an iPhone 3GS or better, but man that's a good looking game.
Game Center is finally coming out with iOS 4.1, which Jobs said would be available next week. Looking forward to it!
