“Long Way Down” Achievement & Trophy
In Mission 4: Proxy War — Objective: Secure Armory, during the first big enemy encounter, you will see two helicopters flying around. It is recommended to grab the “Kar98K” sniper rifle at the start of this mission (in the first room next to the staircase). Aim the sniper rifle at the pilot –- he will be outlined in red so he is easy to see. Shoot at the pilot to down the helicopter and get the “Long Way Down” achievement. If you do not get the achievement, immediately reload the checkpoint.
