Rotor is described as Crazy Taxi with a helicopter, and a Mirror's Edge aesthetic. It's nearly a fitting description, except that I don't remember Crazy Taxi being this hard. Gaaaaaaaaaah.

With a set amount of time on the clock, you're left to zip around the skies above a cityscape, finding missions and grabbing points. Why do helicopter controls have to be so damn difficult? I spent the first several plays crashing into things and generally not finishing a single mission, but eventually you get the hang of it and BAM, Rotor turns out to be pretty decent fun.

There are multiple play types, and the option to set the colours of the city to anything you want. Whatever colours you choose, it looks ruddy ace. The game is just $1 (80 MS Points) from the Xbox Live Marketplace.
