Keys

Keys are only found in the map Nicht so sicherer Raum.

Overview
Keys are needed to open doors when the power is not on.

The number of keys in a game depends on the number of people playing if there are four players they will be three keys, if there are three people playing there are two keys and if they are two people playing there is only one key. Also in solo there is one key due to the fact the player will need to open doors.
