McGyro is a fun target-shooting game where you tilt your iPhone to aim at targets in an Old West setting. You play as the Sheriff McGyro, and your job is to blow away bad guys that appear as wooden targets.
The storyline is presented in comic book format between each part of the three-part missions. Each mission follows a simple formula: the introduction of a bad guy, traveling to the destination, killing the bad guy's evil henchmen, then killing the bad guy. Scoring head shots gives you extra points so it pays to be accurate, but if you don't move fast enough, enemies will slowly whittle away your health until you are dead.
McGyro's default control system is to use the iPhone's accelerometer to aim, then touch the screen to shoot. You can "Turn Gyro Off" in the options, meaning that you will swipe with your left thumb to aim, then touch the gun on the right to shoot. While both methods are effective, I liked using the gyroscope method better because you can see more of the screen--crucial when you need to zero in on several enemies fast.
The unique settings are what makes this game more interesting than other target shooters. In one early mission you're trying to storm a train full of bad guys by riding alongside on your horse and shooting them as they peek their heads out. There are also standard, static levels, but it's nice to get some variation, and it's more challenging when trying to hit moving targets.
Overall, McGyro is a fun diversion and adds a little something more than just target shooting. If you like target-shooting games, this one has a fun storyline, challenging gameplay, and unique settings that add to the fun.
