The Mobile Radar is an Optional Objective found within the cave systems of Terminid Hive Worlds. To complete the Objective, Helldivers must press the button of the Mobile Radar. Once reactivated, it reveals the layout of the cave.

Currently Mobile Radar can only be found on Terminid missions and only on a Hive World. Once reactivated, it reveals key information on the map, such as Terminid Nests, Optional Objectives, and Minor Places of Interest.

The Mobile Radar remains hidden inside caves until it is either spotted (pinged) by a Helldiver or physically discovered by reaching its location. Due to the valuable information it reveals, locating the station early in the mission should be a priority.
