Ambush the Train | Main Missions GUN Guide
Last update: 11 May 2016
Get on the horse and move behind Clay. When you'll reach the tunnel, take the TNT barrel from the cart and place it under the rocky boulder [1]. Do the same with two other barrels and move forward. You should arrive near the train (firefight), so take down all defenders [2], and then take care of gunmen on the horses.
Return with Clay to your trap and place the fourth explosive barrel near the rock. Go up, aim at the TNT [1] and patiently wait, until the detonation sign will appear (the meter on the left side of the screen). The train should stop. Eliminate all guards [2], who will run from the carriages. Mission complete.
