-via linkTo highlight Apple’s Game Center coming to iOS 4.1, Apple brought Epic Games on stage at today’s keynote event to showcase a new game scheduled for release in a few months. That game, code-named Project Sword, is staged in a medieval-era world with lush graphics using the Unreal Engine 3 development framework. As pointed out by Touch Arcade, a demo featuring the world of the game is already available in the App Store.
Epic Citadel is a free universal app. Weighing in at a hefty 82.2 MB, you’ll probably want to wait until you get home to download it on your computer. This is just a demo that allows you to walk around and explore the game’s environment, which is positively vibrant on our iPhone 4 and iPad. Note that this demo will only work on the iPad, iPhone 4, iPhone 3GS, and 3rd-generation or later iPod touch.
