Kill all the Reds on the THE CHASE level. [Bronze / 10G]

Location: The Chase
During the "The Chase" chapter you have to kill all enemies. The only tricky part is in the very beginning, before getting on the train. There will be 3 waves of enemies. In the first two waves you have to kill the enemies on the railcars (8 enemies). In the third wave you have to kill 5 enemies on the train (1 on the back of the train, 4 standing at the railing). You might want to use your military rounds instead of the normal ammo. The military rounds do a lot more damage and make this easier. Once you are on the train you need to kill all the remaining enemies. The trophy / achievement will pop when reaching the end of the train.
