You need a better Perk

You need a better Perk is a minor easter egg featured in Wald des Todes. It is only availible on Solo, as it's effect is only useful on Solo. Upon completion, the Quick Revive machine will appear in the starting room. It has three steps. In Co-Op mode, Quick Revive still spawns where it did in Der Riese.

Step 1
At the beginning of the match, the player must hold the "use" button on the panel next to the mainframe. It will spark and set fire to the tree next to it. The player then must survive to Round 3 before they can progress.

Step 2
Upon reaching Round 4, the tree will crack from the fire and crash into the electrical devices near the mainframe. This causes the floor to crack open, and the player must return to the panel and knife it to cause the Quick Revive machine to rise to the ground (this will replace the electrical devices seen in Der Riese permenatly).

Step 3
The Quick Revive machine will be deactivated, and the player must charge it with the blood of the Zombies. To do this, the player must kill a Zombie with a grenade next to the Quick Revive machine, it will then sing it's jingle and become active. It now has 4 charges before disappearing. When all 4 charges are used, it will sink back into the ground. The easter egg cannot be repeated to bring it back.

Trivia

 * You need a better Perk is a play-on of the lyrics "You need a better revive" from Quick Revive's jingle.
