Eliminate: GunRange Free (link) is a fun, free way to get acquainted with the iPhone 4′s new gyroscope hardware (free if you don’t mind be spammed with ads, but there’s also a $0.99 ad-free version). GunRange has you taking out cardboard shooting-range targets by moving the iPhone left or right—no tilting, just moving the entire iPhone. We like gyroscope controls better because you can keep the screen flat and not lose any screen visibility like you do with tilt controls.

The game also has some nice high-res graphics that take advantage of the iPhone 4′s Retina Display screen.

Overall, it’s not exactly a revolutionary game, asyou’re just taking out cardboard targets. And there are only three different areas that you play over and over. But you earn credits in game that you can use upgrade your guns. I had fun playing it, although the gyroscope needed constant recalibration and the ads are crazy annoying between every level.

Eliminate: Gunrage Free is a free download from the iTunes App Store.
