Eliminate: Gun Range is for iPhone 4 Only

Ngmoco isn’t pandering to the 3GS-and-earlier crowd for Eliminate: Gun Range, the first game I’ve seen that’s specifically for iPhone 4, which launches Thursday. The game is a target shootout with 12 high-fidelity weapons and 3 shooting ranges with 144 challenges. According to TouchArcade, Eliminate: Gun Range uses iPhone 4′s gyroscope for more accurate aiming. Real Racing, out already for existing iPhones, also uses the iPhone 4′s gyroscope.

Earlier iPhones don’t have gyroscopes, only accelerometers. While the latter excels at detecting horizontal or vertical movement, they get confused by rotation, and that’s where the gyroscope comes in. Here’s a video on YouTube that explains the difference between accelerometer and gyroscope in detail. iPhone 3GS owners, fear not: Ngmoco says it’s working on Eliminate: Gun Range support for you, too.

We should see lots of other games get the iPhone 4 treatment in the days ahead, but the differences will largely be cosmetic, taking advantage of the phone’s higher-resolution display. I doubt we’ll see many games using iPhone 4-specific features that shut out earlier phones, but some augmented reality with the front-facing camera could be neat. [via TouchArcade, thanks Aqualung!]
