Bootant's Crazy Choppers [App Store] came out a few days ago, and since then has generated a bit of a fan following on our forums. With simple tilt controls, a basic upgrade system, and five different locales to decimate various enemy vehicles, Crazy Choppers is a steal at 99¢.

While flying around, you need to carefully keep an eye on both your health and fuel gauges. After the first few levels, enemies start firing back, forcing you to take evasive maneuvers and multiple attack runs to avoid enemy fire. To refuel and repair, simply check your radar for the nearest green dot indicating a friendly helipad to land on.

When you're getting gassed up and your bullet holes patched, you're also offered an upgrade screen to spend some of the money you've earned by upgrading your offensive and defensive capabilities, as well as increasing the capacity of your fuel tank. Initially, you burn through gas extremely quickly, but after a few upgrades the game becomes far more enjoyable.

Bootant posted a gameplay video on our forums:

The controls are great and can be calibrated at any time during by pausing the game, and while the gameplay is more in depth than Crazy Tanks [App Store], it would be nice to have a greater weapon selection. Still, if you like helicopter games, Crazy Choppers is hard to pass up for 99¢.
