Dead rails

You hear a gunshot, and the outlaws are running towards the flatcar, shouting. They are wearing bandanas over their faces and have guns in their hands. You have to defend yourself.

The outlaws keep running towards you, their guns pointed at you. You have a clear shot, but the outlaws are too close. You don't have time to reload, so you have to make this shot count.

The outlaws fall to the ground, one after the other. They don't move or say anything. You have successfully defended yourself, but the flatcar is still moving. You hear footsteps behind you.
