Sounds like a fun and free way to kill some time.

Players can pick their favorite version, and tap the on-screen buttons to play the sounds of the in-game handgun, machine gun, shotgun and grenade launcher. However, if you purchase/download the current version of the applicationon either a newer iOS device (like your iPhone 6) or using the iTunes desktop software on your Windows or Macthen the older version of the application will be accessible to your older device.

In addition to Controller Mode, the app has a standalone feature called Toy Mode that allows gamers to recreate the shooting sounds from the Time Crisis series, including the three classic types of GunCon usable in Controller Mode as well as international models. Players can line the crosshairs up with enemies and tap the Trigger area to shoot your way through the game as it was originally intended. The device running iGunCon will display a Trigger, Action and Reload areas, while the device running the game will show crosshairs. Players can download iGunCon on their iPhone 4 or iPad 2 for free, then link it with another iPhone, iPod touch, iPad or Mac that is running Time Crisis 2nd Strike and they will sync up, allowing them to play the game the way it was meant to be played.

Namco Bandai have released iGunCon, a free app that lets players use their iPhone 4 or iPad 2 as a controller for shooting titles Time Crisis 2nd Strike for iPhone and iPod touch, Time Crisis 2nd Strike HD for iPad and Time Crisis 2nd Strike on the Mac App Store.
