In the episode which you are Ray chasing the train that Billy jumped on, there is a secret weapon to be found. They are called Prime Rangers, and are two powerful and equally beautiful pistols which do not rust or wear during the level. In order to find these weapons, you must search the train cars as you pass them by. If you look carefully, you will find them. There is a chest hidden behind a stack of boxes on one of these cars. If you jump over the stack and open the chest, you will see the two long beautiful pistols underneath you. Pick them up and shoot up all the cattle rustlers and hombres as desired.
