KF2 Day of the ZED: Netherhold Objectives and Skull Hunt
This page is a translation of a Russian Steam guide made to help players earn the "Forgotten Knowledge" achievement (the Russian client name; roughly the collectibles achievement) and complete the stages of the seasonal event "Day of the ZED" in Killing Floor 2. The event map is Netherhold (called "Halls of Despair" in the Russian client). Note: names of achievements and objectives below are literal translations of the Russian names used by the author, so the English client may word them differently.
Introduction: the five stages
The five Day of the ZED objectives, with rewards listed at the bottom.
There are five stages in total. All of them can realistically be done in one run of Endless on Netherhold.
Collectibles and hidden rooms
The horned skull collectible you need to find.
For the "Forgotten Knowledge" achievement you must collect 10 collectibles shaped like horned skulls on Netherhold. Two of the event stages ("It Comes From the Wall" and "Purple Taint" in the Russian wording) require finding hidden rooms on the map. To combine the achievement with these two stages, the author attached a video showing where the collectibles are, where the hidden rooms are and how to open them.
Stage: Terrifying Manifestations
Kill 15 bosses on any map, on any difficulty, in any mode. This takes the most time, but a few hours of Endless matches are enough.
Stage: Weekly Cult
Play the Weekly mode on Netherhold and survive until the end. At the time of writing the weekly outbreak was "Arachnophobia", which the author found very easy.
The weekly outbreak at that time: Arachnophobia.
Stage: Eternal Torment
Beat wave 15 in Endless on Netherhold at Hard difficulty or higher. You can join a game in progress or start your own and play through 15 waves.
Starting an Endless game from the single-player menu.
