Road warrior

This is an endless shooter and runner game. our vehicle is a car fitted with gun above it and has infinite number of bullets to fire on. All the game is based on night scene in a battleground in fences. Initially we we have military vehicles approaching towards us. our car is moving forward with constant speed and we need to destroy military vehicles.
Destroying each enemy vehicle awards us 1 point and as our score passes 10, then along with military vehicles , we have civilian cars approaching towards us but we are not supposed to fire on them. If we did, our game will be over and this level has fog and dim visibility. As score increases fog density increases and now we have mines fitted in the roads also. If we collided with them our car will get destroyed. Collision with any type of vehicle and fence will also lead to destruction of our car and thus game over. We are supposed to use accelerometer to move left/right.
