I uploaded a demo. Unfortunately I don't have enough spare time working on it. The progress is very very slow, there are no real enemies, no AI, all assets are freely available on internet. You just move and shoot, and you will not die.
I am considering to submit it to Winter 2007 contest.
Enjoy.

Control:
Movement: WASD
Camera: Q - rotate left, E - rotate right, Mouse-wheel - zoom
Hold left mouse button - shooting and lock targets
Release left mouse button - fire missile to locked targets
