We elect to head for the brush.
We go off-road, going onto the forest foliage to get the helicopter away from us. Bill seems to know his stuff, driving carefully along the forest brush and ensuring that none of it snags the car. However, one thing we did not account for: the heat of the bullets. Suddenly, as some of the machine gun bullets hit the forest ground, the light into flame, burning some of the underbrush as we drive quickly away.
The helicopter seems to stop following us in that moment, turning away and allowing us to drive further into the forest. Eventually, we come to a bit of a stop, with Bill taking a few breaths. He looks more stressed than before.
