Majic Jungle Software has Chopper 1 and Chopper 2 (iTunes Link) in the iTunes App Store and Chopper 2 in the Mac App Store Link for 99-cents (regularly $4.99) each for a limited time.

Chopper 1 features 20 levels in each of four difficulties. Tilt to fly, and touch the screen to drop bombs or fire your machine gun.

Chopper 2 features 36 action packed missions over 12 unique and beautiful locations. It features a completely re-written 3D game engine, all new enemies, weapons, graphics, and missions, while still retaining the classic side scrolling game-play.

Escort a convoy of vehicles across the desert, or defend a train from enemies emerging from underground mines. Use your laser sight to line up enemies emerging from stairwells in the city. Chase down lines of enemy tanks and choppers while avoiding heat seeking missiles, gunfire and bird strike. Help your allies defend against advancing armies, and rescue stranded civilians, all while trying to complete your mission as fast as possible for the highest score.

Chopper features OpenFeint leaderboards and achievements. It is universal for iPad and iPhone/iPod touch, with HD graphics on both the iPad and iPhone 4. It uses the gyroscope where it can for increased control, OpenAL for spatial sound effects and even features an original 17 minute long soundtrack.

If you have both an iPad or Retina display device (iPhone 4 or 4th generation iPod touch) and any other iPhone or iPod touch, you can use the fantastic remote control feature to wirelessly control the iPad/Retina display device with an iPhone/iPod touch over bluetooth or wifi. Then plug the iPad/Retina display device into a TV or display through the component cable or VGA adapter and play Chopper 2 on your TV from your couch!

Note: TV output is only supported from an iPad, iPhone 4, or 4th generation iPod Touch and only when using the bluetooth/wifi remote control feature.

Chopper 2 can also be used to control the Mac version.
