Epic's spectacular Unreal Engine 3 tech demo free at iTunes App Store

Did you oooh and ahh at the fantastic gaming graphics that accompanied today's Apple keynote? You won't have to wait for next week's iOS 4.1 to get a taste of those textures for yourself. Though the full-on gladiator dueling of Epic's "Project Sword" may be a while off, you can get your hot little hands on "Epic Citadel" right now, a 82.2 megabyte download that explores a beautiful medieval castle town. Oh, and did we mention it's free? Even id Software's mindblowing 60FPS Rage demo must be quaking in its boots right about now.
