This objective is exciting for 2 reasons: 1) there is an element of chance to it, and 2) it feels like a plausible objective for the map, because the shipping crates belong there and the narrator ties it in well. Here is an example: KF1-FrightYard has an objective where you unweld shipping crates and look for parts. And it comes down to one simple thing: variety of objectives. Sadly, what we got was a lifeless and pathetic objective mode that is basically universally hated by the KF2 community.
For those of us who played the mode in KF1, we knew what a fun twist objectives put on the gameplay and how much life they added to maps. I think I speak for many in the Killing Floor community when I say that we were excited to hear that objective mode was being added into KF2.
