It's an excellent game, very polished, and while it starts out simply, the combat builds up well. It controls about the same as the last game (tilt to fly the chopper, and tap the screen to fire), but the firing controls have been refined. The presentation is probably the most amazing thing, actually -- the 3D world looks terrific, the music is excellent, and the titles on screen are in a kind of 3D as well, so that they seem to actually float in the game's real-world space. All in all, it's a very cool game and some excellent work by Frampton's Majic Jungle Software.
The game is universal for both iPad and the iPhone, and if you install it on both, you can actually play the iPad version with the iPhone or iPod touch as a controller. It's not a huge gamechanger, but it is a fun extra feature that probably required some coding work to get going. If you've been waiting for this one like we have, it's on the App Store ready for you right now.
