Airstrike is a 2D dogfighting game being slowly developed by various people around the net. It is not yet playable although there is an old version which may be a bit fun to try.

The source code and the 3D models are released under the GPL licence.

Changes:

Menu works better
You can change controls and save them. If saved, they are automaticllay loaded next time you start.
When game starts, sound is set to 50%.
You can in/de-crease sound with GP2X Vol keys.
