Namco Bandai has released a free application for iPhone 4 and iPad 2 called iGunCon. This would be fairly dull news if it was a regular free app, but this one seems like a lot of fun - it allows players to use their devices for lightgun shooters Time Crisis 2nd Strike on iPhone, iPad and Mac.
By downloading the application, you can link it with another iOS device running the game, and it will turn your device into a light gun. You'll move one device to aim and fire, while the other device will display the action and the crosshairs.
In addition to Controller Mode, the app has a standalone feature called Toy Mode that allows gamers to recreate the shooting sounds from Time Crises games, which should be a fun way to piss off your friends.. 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.
